This is an annotated checklist of all recognized and named taxa of freshwater fishes of Iran, documenting recent changes and controversies in nomenclature, and including primary synonyms, updated from the Jouladeh-Roudbar et al. (2015b) checklist. We provide an updated comprehensive listing of taxonomy, diagnostic and meristic characters, names, and conservation status, including detailed distribution maps. We strive to record the most recent justified taxonomic assignment of taxa in a hierarchical framework, providing annotations, including alternative possible arrangements, for some proposed changes. We provide common English and Persian names and detailed distributional data for all taxa, listing occurrence by basins, including indications of native, endemic, and translocated populations. We used the IUCN Red List Categories and Criteria for classifying species at high risk of global extinction. The diversity of freshwater fishes of Iran included in this checklist, consists of 274 recognized species in 100 genera, 33 families, 20 orders and 3 classes. Also, for the first time we report and confirm the presence of seven species Aphanius kruppi, Capoeta kaput, Luciobarbus conocephalus, Oxynoemacheilus veyselorum, O. gyndes, O. hanae and Squalius latus from Iran basins. The confirmed freshwater fishes of Iran comprise 264 species in 97 genera, 33 families, 20 orders and 3 classes. Of the 241 endemic and native fish species listed the conservation statuses are as follows, 1 Extinct in the Wild (EW), 17 Critically Endangered (CR), 12 Endangered (EN), 15 Vulnerable (VU), 9 Near Threatened (NT), 148 Least Concern (LC) and 39 Data Deficient (DD). Forty four fish species (18.3% of 241 species listed) are officially regarded as globally Threatened (Critically Endangered [CR], Endangered [EN], or Vulnerable [VU]). These numbers and percentages of Threatened species have increased since the last checklist.

We have carried out a comparative analysis of the morphological features of Twaite shad Alosa fallax based on our own data (Curonian Lagoon, Baltic Sea (2008 and 2009)) and comparative materials (collections of Russian and foreign natural history museums, including published data). The results of this study allow us to assign the Baltic Sea population of Twaite shad to the taxonomic status of subspecies Alosa fallax
balticus subsp. nov. The Baltic Sea subspecies differs from other subspecies of Atlantic Twaite shad A. fallax by a lower number of gill rakers (mean 36.7) and vertebrae (53.6) and larger pre dorsal distance (46.2% SL or 41.6–42.7% TL). A. fallax balticus is one of the subspecies that have the lowest number of gill rakers on the first gill arch among subspecies of the species Alosa fallax in the northeastern Atlantic and seas of its basins.

Проведен сравнительный анализ морфологических особенностей финты Alosa fallax на основе собственных данных из Куршского залива Балтийского моря (2008 и 2009 гг.) и сравнительных материалов из российских и европейских естественнонаучных музеев с привлечением литературных данных. Результаты позволяют присвоить балтийской популяции финты подвидовой статус Alosa fallax balticus subsp. nov. Балтийский подвид отличается от других подвидов атлантической финты A. fallax меньшим числом жаберных тычинок (в среднем 36.7) и позвонков (53.6), а также бóльшим антедор-сальным расстоянием (46.2% SL, или 41.6-42.7% TL). Для A. fallax balticus характерно одно из самых низких значений числа жаберных тычинок на первой жаберной дуге среди подвидов вида Alosa fallax Северо-восточной Атлантики и морей ее бассейна.
... Here, we test whether these australian biogeographic provinces, but more specifically the Bassian Isthmus, represent significant historical barriers to a globally distributed species complex of round herring (genus Etrumeus), known as " Maray " in australian waters. This is a small inshore pelagic clupeid that exploits the coastline out to the edge of the continental shelf and inhabits tropical to temperate waters (Whitehead 1985; lavoué et al. 2013). In this study, we assess gene flow between regions, determine whether genetic signatures of historical isolation are retained in the mitochondrial genome, and compare potentially diagnostic morphological and meristic traits for individuals sampled across this broad southern australian coastline. ...
... round herrings have a turbulent taxonomic history, most recently classified as a single, circum-global species , Etrumeus teres DeKay 1842 (now Etrumeus sadina Mitchill 1814), along with a sister species (Etrumeus whiteheadi Wongratana 1983) found in sympatry over a limited range in southern africa. Etrumeus is discontinuously distributed across the world's major oceans from 40°n to 40°S (Whitehead 1985). recent genetic appraisals, combined with an evaluation of conspicuous morphological traits (e.g., gill rakers and coloration), revealed isolated species in the northwestern atlantic (Bay of Fundy to the gulf of Mexico), eastern Pacific (California to Baja California), central Pacific (Hawai'i), northwest Pacific (Japan), western Indian Ocean (Durban to northeastern Somalia), and the northern red Sea now into the Mediterranean (randall and DiBattista 2012; DiBattista et al. 2012). ...
... In the last revision of clupeoid fishes (Whitehead 1985), nine geographically isolated populations of E. teres (now E. sadina Mitchill 1814) were defined, including Japan and Taiwan, southern australia, the entire east coast of africa and eastern Mediterranean, north america from the Bay of Fundy to the gulf of Mexico, the northern coast of South america from Colombia to the guianas, California and Baja California, galapagos Islands, Peru, and the Hawaiian Islands. Whitehead (1985) was unable to discriminate between regional populations owing to overlapping morphological characters and meristics; all fish in this genus were therefore synonymized with E. teres. ...
Molecular genetic surveys of marine fishes have revealed that some widely-distributed species are actually a composite of multiple evolutionary lineages. This is apparent in the round herrings (genus Etrumeus), wherein a globally distributed taxon (Etrumeus sadina Mitchill 1814) has proven to contain at least seven valid taxa, with more likely awaiting discovery. Here we survey the evolutionary lineages of the nominal E. sadina (formerly E. teres, a junior synonym) across the southern temperate zone of Australia, a marine region divided into three biogeographic provinces based primarily on the distribution of intertidal faunas. Results from morphological and mitochondrial DNA data reveal two evolutionary lineages corresponding to eastern and southwestern provinces (d = 0.007 for cytochrome c oxidase subunit I and d = 0.017 for cytochrome b), possibly initiated by the Bassian Isthmus between Australia and Tasmania during low sea level stands. The Australian round herring is also genetically distinct from the nearest congeneric forms in the Indian and Pacific Oceans, with a corresponding modal difference in gill-raker counts in most cases. Based on these data we resurrect the title Etrumeus jacksoniensis for the Australian round herring. While the Bassian Isthmus may have initiated the partition of evolutionary lineages within Australia, additional oceanographic and ecological factors must reinforce this separation in order to maintain diagnostic genetic differences along a continuous temperate coastline.
... One such species, Platanichthys platana (Regan, 1917), is the Clupeidae found in Brazil (Menni, 2004;Oliveira, 1997), whose typelocality is the Río de La Plata. This species inhabits coastal, freshwater, and brackish waters in the lagoons, estuaries, and rivers of southeastern South America, specifically from the Brazilian state of Rio de Janeiro to the La Plata region of Argentina, and Uruguay (Di Dario et al., 2011;Fialho et al., 2000;Nanini-Costa et al., 2016;Whitehead, 1985). Initial surveys of P. platana were conducted in the upper Rio Paraná basin in 2007 , but this species was not observed in the upper Rio Paraná floodplain (URPF)the only stretch of the Rio Paraná in Brazil that remains free of dams (Ota et al., 2018)-until 2012. ...
... For instance, a first supramaxilla was very small or absent, and the number of pelvic-fin rays distinguished it from members of the genus Lile, whereas the presence of posterior fontanels set it apart from the Ramnogaster and other species of Lile. Morphologically, P. platana is characterized by the presence of a silvery lateral band (when alive) and posterior frontal fontanel in adults, a clear temporal foramen, the absence of a lateral line, a superior mouth, tiny or absent supramaxilla, and an elongated body (Cione et al., 1988;Campello & Bemvenuti, 2002;Whitehead, 1985). ...
The first records of Platanichthys platana in the upper Rio Paraná floodplain (URPF) date to 2012, but variations in the body length of specimens collected from this basin have since generated uncertainty about their identity and origin of introduction. This study aimed to genetically characterize populations of P. platana in different river basins, assess haplotype diversity, and determine the origin of the introduced population in the URPF. Sequences from the COI region were used to calculate genetic distances, construct gene trees, and identify haplotype networks. Eight haplotypes were found, several of which were exclusive to the coastal basins of Santa Catarina and Rio Grande do Sul, and the Río Negro basin (Río Yí). The Río de La Plata and Mar Chiquita basins, and upper Rio Paraná floodplain shared haplotypes. Based on the results of our analysis, we concluded that the URPF specimens were introduced from populations in Argentina.
... The Japanese grenadier anchovy Coilia nasus, an oceanriver anadromous fish with spawning migration behavior, lives in the Yangtze River, coastal waters of China and Korean peninsula, and also in the Ariake Bay in Japan (Whitehead et al. 1998;Zhu et al. 2014;Du et al. 2014;Shen et al. 2015;Duan et al. 2015;Zhou et al. 2015). At spawning time every spring, mature C. nasus individuals migrate over long distances from ocean to freshwater lakes to spawn (Whitehead et al. 1998;Zhu et al. 2014). ...

To better understand the spawning migration of C. nasus to enable its conservation, it is necessary to study the potential migration genes that govern C. nasus. ...
Olfaction is essential for fish to detect odorant elements in the environment and plays a critical role in navigating, locating food and detecting predators. Olfactory function is produced by the olfactory transduction pathway and is activated by olfactory receptors (ORs) through the binding of odorant elements. Recently, four types of olfactory receptors have been identified in vertebrate olfactory epithelium, including main odorant receptors (MORs), vomeronasal type receptors (VRs), trace-amine associated receptors (TAARs) and formyl peptide receptors (FPRs). It has been hypothesized that migratory fish, which have the ability to perform spawning migration, use olfactory cues to return to natal rivers. Therefore, obtaining OR genes from migratory fish will provide a resource for the study of molecular mechanisms that underlie fish spawning migration behaviors. Previous studies of OR genes have mainly focused on genomic data, however little information has been gained at the transcript level. In this study, we identified the OR genes of an economically important commercial fish Coilia nasus through searching for olfactory epithelium transcriptomes. A total of 142 candidate MOR, 52 V2R/OlfC, 32 TAAR and two FPR putative genes were identified. In addition, through genomic analysis we identified several MOR genes containing introns, which is unusual for vertebrate MOR genes. The transcriptome-scale mining strategy proved to be fruitful in identifying large sets of OR genes from species whose genome information is unavailable. Our findings lay the foundation for further research into the possible molecular mechanisms underlying the spawning migration behavior in C. nasus.

... The Japanese grenadier anchovy Coilia nasus is a famous small-sized commercial fish that is widely distributed in the coastal waters of China, the middle and lower reaches of the Yangtze River, Ariake Bay of Japan, and the western coastal waters of the Korean Peninsula (Whitehead et al. 1998;Zhu et al. 2014;Yuan et al. 1980). Anadromous C. nasus lives in the sea until it reaches sexual maturity and then performs ocean-river migration behavior to the exorheic rivers through long-distance swimming to spawn (Whitehead et al. 1998;Zhu et al. 2014;Yuan et al. 1980). ...

However, the molecular mechanisms of spawning migration of anadromous C. nasus have not been clarified yet. ...
A number of studies have suggested that olfaction plays an important role in fish migration. Fish use several distinct families of olfactory receptors to detect environmental odorants, including MORs (main olfactory receptors), V1Rs (vomeronasal type-1 receptors), V2Rs (vomeronasal type-2 receptors), TAARs (trace amine-associated receptors), and FPRs (formyl peptide receptors). The V1Rs have been reported to detect pheromones, and a pheromone hypothesis for the spawning migration of anadromous fish has been proposed. Examining whether Coilia nasus relies on V1R-mediated olfaction for spawning migration is important for understanding the molecular basis of spawning migration behavior. Here, we explored the V1R gene family in anadromous C. nasus. Six V1R genes previously reported in other teleost fish were successfully identified. Interestingly, we detected the largest V1R repertoire in teleost fish from C. nasus and identified a species-specific expansion event of V1R3 gene that has previously been detected as single-copy genes in other teleost fish. The V1R loci were found to be populated with repetitive sequences, especially in the expanded V1R3 genes. Additionally, the divergence of V1R3 genetic structures in different populations of C. nasus indicates the copy number variation (CNV) in V1R3 gene among individuals of C. nasus. Most of the putative C. nasus V1R genes were expressed primarily in the olfactory epithelium, consistent with the role of the gene products as functional olfactory receptors. Significant differences in the expression levels of V1R genes were detected between the anadromous and non-anadromous C. nasus. This study represents a first step in the elucidation of the olfactory communication system of C. nasus at the molecular level. Our results indicate that some V1R genes may be involved in the spawning migration of C. nasus, and the study provides new insights into the spawning migration and genome evolution of C. nasus.
... based laboratory, all samples were observed at binocular and fish eggs and larvae were sorted from the rest of the plankton. Eggs and larvae of Sardinella aurita were identified (Whitehead, 1988). The number of fish eggs and larvae collected at each station was standardized to the number beneath a unit of sea surface (10 m 2 ) using the equation of Nonaka et 25 al. (2000): 10 m 2 of sea at station i , x i is the number of larvae/eggs taken at station i , v i is the volume of water filtered in m 3 and d i is the maximum depth reached by net. ...
... Eggs and larvae preserved in formaldehyde were used for the determination of the stage of development. In particular, staging of eggs were performed assigning number from 1 (stage after fecundation, with a single cell) to 11 (stage pre-hatching) follow 5 (Gamulin and Hure, 1955;Whitehead, 1988). We considered stage from 1 to 4 "early stage", from 5 to 8 "middle stage" and from 9 to 11 "late stage". ...
Multidisciplinary studies are recently seeking to define diagnostic tools for fishery sustainability by coupling ichthyoplanktonic datasets, physical and bio-geochemical oceanographic measurements, and ocean modelling. The main goal of these efforts is the understanding of those processes that control fate and dispersion of fish larvae and eggs and thus tune the inter-annual variability of biomass of fish species. We here analyzed eggs and larvae distribution and biological features of Sardinella aurita in the northeast sector of the Sicily Channel (Mediterranean Sea) collected during the 2010 and 2011 summer cruises. We make use of satellite sea surface temperature, wind, and chlorophyll data to recognize the main oceanographic patterns that mark eggs and larvae transport processes and we pair these data with Lagrangian runs. To provide a physical explanation of the transport processes that we observe, we hire a potential vorticity (PV) model that takes into account the role of wind stress in generating those cold filaments responsible for the offshore delivery of eggs and larvae. Our results show that the strong offshore transport towards Malta occurring in 2010 is related to a persistent wind forcing along the southern Sicilian coast that generated an observable cold filament. Such a pattern is not found in the 2011 analysis, which indeed shows a more favorable condition for sardinella larvae recruiting with a weak offshore transport. Our results want to add some insights regarding operational oceanography for sustainable fishery.

Background
Coilia nasus (Japanese grenadier anchovy) undergoes spawning migration from the ocean to fresh water inland. Previous studies have suggested that anadromous fish use olfactory cues to perform successful migration to spawn. However, limited genomic information is available for C. nasus. To understand the molecular mechanisms of spawning migration, it is essential to identify the genes and pathways involved in the migratory behavior of C. nasus.
Results
Using de novo transcriptome sequencing and assembly, we constructed two transcriptomes of the olfactory epithelium from wild anadromous and non-anadromous C. nasus. Over 178 million high-quality clean reads were generated using Illumina sequencing technology and assembled into 176,510 unigenes (mean length: 843 bp). About 51% (89,456) of the unigenes were functionally annotated using protein databases. Gene ontology analysis of the transcriptomes indicated gene enrichment not only in signal detection and transduction, but also in regulation and enzymatic activity. The potential genes and pathways involved in the migratory behavior were identified. In addition, simple sequence repeats and single nucleotide polymorphisms were analyzed to identify potential molecular markers.
Conclusion
We, for the first time, obtained high-quality de novo transcriptomes of C. nasus using a high-throughput sequencing approach. Our study lays the foundation for further investigation of C. nasus spawning migration and genome evolution.
... The family Clupeidae (Nelson, 1970) the most specious group within the Clupeiformes (approximately 208 species, Fishbase, September 2008:http://www.fishbase.org/search.php) includes five subfamilies of the marine coastal, some freshwater and anadromous schooling fishes (Grande, 1985;Nelson, 1970;Whitehead, 1985;Whitehead et al., 1988). Several authors have noted that two of these subfamilies, Alosinae and Clupeinae, are certainly not monophyletic (Grande, 1985;Nelson, 1970) but they left unchanged their classification pending clarification from additional studies (Lavoué et al., 2007). ...
In the Southwestern Atlantic Ocean, several described species of Clupeiformes overlap their geographical distribution in the coastal areas from Rio Grande do Sul (Southern Brazil) to Bahía Blanca (Argentina) and the Río de la Plata estuary. Larvae and juveniles of the SW Atlantic menhaden Brevoortia aurea are very difficult to discriminate from those of other clupeids belonging to the genera Platanichthys and Ramnogaster inhabiting the same environments. Here we implemented phylogenetic analyses based on mitochondrial cytochrome b sequences and morphometric and osteological studies to achieve unambiguous species recognition in different ontogenetic stages of six endemic species of Clupeiformes from the Southwestern Atlantic Ocean. All phylogenetic analyses based on the cytochrome b gene yielded a robust support to the existence of highly structured and monophyletic groups conforming clupeiforms taxa. These monophyletic entities were consistent with major groups accessed through the first two principal components (PCs) from morphometric variation among taxa. Both approaches resulted in accurated and complementary tools for the individual assignment in clades and groups within Clupeiformes during different ontogenetic stages in their life cycle. The detection of species-specific spawning and nursery areas through accurated methodological approaches of identification constitute a prerequisite for a sustainable management in pelagic fisheries.
... The species is a pelagic predator that migrates northward to the subtropical convergence zone (Pütz et al., 2007), coinciding with the migration of one of their main prey species, the Argentine anchovy (Engraulis anchoita) (Silva et al., 2015;Yorio et al., 2017;Marques et al., 2018). This anchovy is widely distributed across the continental shelf of South America in the southwestern Atlantic Ocean, from the Cabo de São Tomé, state of Rio de Janeiro in Brazil, to central Patagonia (47 • S) in Argentina (Whitehead et al., 1988). Adult Argentine anchovy inhabit waters at depths of 30-150 m off the coast of the municipality of Rio Grande, Brazil, and along the Uruguayan coast, while juveniles occur along the coast at a depth of 30 m (Castello, 1997;Costa et al., 2020). ...
Food availability and oceanographic conditions drive the distribution and movement of marine vertebrates. Tracking efforts towards seabirds usually focus on their breeding period, tagging adults in colonies. In this study, we tracked four juvenile and one adult Magellanic penguin (Spheniscus magellanicus) with satellite transmitters. These individuals were caught incidentally in gillnets and were tagged at sea, with the exception of the adult that was rehabilitated and released on the beach. The penguins were tracked in their wintering grounds, where behavior and oceanographic characteristics of the area used were determined. All five birds remained along the coast of southern Brazil and Uruguay in neritic waters up to 10 km offshore and 50 m in depth. The four juveniles used a mean area of 1,426 km 2 , travelling on average at 7.4 km/h. The high turning angles observed and mean sinuosity of 2.46 indicated that the penguins were foraging. The adult penguin covered an area of 1,033 km 2 , at a mean speed of 4.6 km/h, and with low sinuosity (0.43), which is suggestive of either travelling movements or an experienced hunter who needs a few turning angles to forage. The adult travelled 538 km in total, reaching a maximal distance of 465 km. Locations were obtained over a period of 7-10 days, and all five penguins remained in waters of the coastal branch of the Malvinas Current, an area characterized by cold sea surface temperatures (SST, mean = 13.4 • C) and high primary productivity. Salinity values (34.06 PSU) were also typical of the Malvinas Current and were influenced by the La Plata River plume, whose waters are low in salinity and nutrient rich. All five penguins remained near the coast probably because these waters are rich in nutrients, and carry the penguins' main prey, the Argentine anchovy (Engraulis anchoita). Regarding conservation concerns involving these penguins, we highlight the current management of the anchovy fisheries and the development of offshore windfarms that could potentially cause major disturbances to the penguins' foraging habitat. The establishment of the Albardão National Park in the nearshore area used by the penguins is highly desirable for the protection of the species and their feeding resources.

... The examined specimens come from the type locality of Mondaino, Italy (Fig. 7). The presence of the postpelvic scutes (Whitehead 1985) and the lack of a second dorsal fin (Whitehead 1988) means that the examined specimens are Clupeiformes and certainly not Myctophiformes. The jaw articulation behind the orbit clearly points to the family Engraulididae (anchovies) (Whitehead 1985). ...
Clupeidae (herring) fishes form a substantial part of the Miocene ichthyofaunas of Europe, but their taxonomy is poorly investigated. Part of the reason is the lack of information on the osteology of extant clupeids, as well as on their inter-and intraspecific variation. Here a study of the meristics, morphology and relative body measurements of selected fossil and extant clupeids is presented. Nine species of extant and 14 fossil species of clupeids were examined. The data were obtained by microscopic observations, radiographs and digital images. Landmark-based measurements were taken on X-rays (extant) or photos of the specimens (fossils). Principal Component Analysis and Cluster Analysis were used to analyze the data. The description or reexamination of nine Miocene clupeid "species" confirmed previous claims that most are in need of revision, especially those from the Central Paratethys. Only two species were in no need of revision; one was reattributed to a different family and the rest were either reassigned to different genera or found to include specimens which were wrongly identified. Some species names might become invalid because of the bad state of preservation of some fossil holotypes. A cluster analysis for the fossil and extant clupeids that was based on seven meristic characters failed to give monospecific groups for the fossils which clustered with each other rather with their extant relatives,. The relative body proportions analysis seemed to fit better than the results of the meristic analysis with previous phylogenetic hypotheses for the extant clupeids, but the fossils still grouped mostly together. Some taxonomically useful branchiocranial characters were also introduced or reexamined and it seems that the extant genera Clupea, Alosa, Clupeonella can be distinguished from each other through a combination of those. The results, unless biased by the taxon sampling, may indicate that some clupeid genera (Clupea, Alosa, Clupeonella) from the Miocene of the Mediterranean/Paratethys Basins were more similar to each other concerning body proportions and meristics than their relatives are today. The identification of fossil clupeid genera can be effectively done in well preserved specimens by traditional methods, but new approaches, such as geometric morphometric analyses, could be useful in identifying some fossil clupeids at the species level.
... Thryssa kammalensis (Bleeker, 1849), a typical pelagic fish, belonging to order Clupeiformes, family Engraulidae, genus Thryssa, is a euryhaline species that is widely distributed in the coastal waters of the Indo-West Pacific (IWP) and is especially common along the coast of China (Whitehead et al. 1988). Thryssa kammalensis prefer to large copepods and ostracods without distinct feeding rhythm (Bleeker 1849). ...
Thryssa kammalensis (Bleeker, 1849) is a common pelagic species in the Chinese Seas and plays an important role in marine ecosystems. In the present study, 196 individuals of T. kammalensis were collected from nine localities along the Chinese coastal waters. The partial control region sequences of them were sequenced for analysis. Variable numbers of tandem repeats (VNTRs) were common in the control regions of all individuals, which led to variation in sequence length, ranging from 772 to 924 bp. All the populations exhibited high haplotype diversity (0.946–1.000) and low nucleotide diversity (0.015–0.031). Two distinct lineages were identified based on the neighbor-joining (NJ) tree, Bayesian inference (BI) trees, and minimum spanning tree (MST). However, the relative frequency of individuals occupying the two major lineages did not differ significantly among sampling locations. In addition, both molecular variance analysis (AMOVA) and pairwise FST analysis strongly supported little genetic differentiation among populations, revealing no significant genetic structure for T. kammalensis. Neutrality tests and analysis of mismatch distribution suggested that recent population expansion occurred in the two lineages. The climatic changes during Pleistocene periods and dispersal strategy leading to the continual gene flow might have played an important role in the geographical pattern of T. kammalensis.
... Engraulidae larvae are related to the SACW in the Cape Frio (Lopes et al., 2006) and it is possible that most individuals of Engraulidae collected were Engraulis anchoita that occurs from Argentina towards Cape of São Tomé (Whitehead, Nelson, & Wongratana, 1988). ...
Many marine organisms spend the early life history stages in neuston domain. Although the importance of ichthyoneuston, few studies were developed in the Southwest Atlantic Ocean. Therefore, this study aimed to improve the knowledge on ichthyoneuston of the Brazilian coast analyzing the vertical stratification and horizontal distribution of these organisms. Neuston samples were collected in daylight between 20°S and 23°S from February to April 2009 (late summer/early autumn; rainy season) and from August to September 2009 (late winter/early spring; dry season). Eggs of six taxa were identified: Anguilliformes, Engraulidae, Clupeidae, Synodontidae, Trichiuridae, and Maurolicus stehmanni (Sternoptychidae). The neustonic larval fish assemblage was composed by 40 families and 63 species. Mullidae and Myctophidae larvae were the most abundant in the rainy period while Mullidae and Mugilidae dominated in the dry season. Seasonal and spatial variation of larval fish assemblages in the neuston were structured by oceanographic features. The larval fish abundance on the outer slope stations may have been favored by the advection of an anticyclone that encompassed most of the study region during the cruise periods. In the rainy season, salinity and local depth structured the larval fish assemblage in a cross‐shelf gradient, while in the dry season the larval assemblage was structured around temperature and north‐south gradient. In the dry season, the cross‐shelf gradient was less pronounced mainly because of the low abundance and frequency of mesopelagic larvae. The low frequency and abundance of some species are probably related to the net avoidance of fish larvae during the day or dial vertical migration, as many species migrate to deeper layers during the day and ascend to neuston only at night. Nevertheless, the present study presented baseline information about the seasonal and spatial variation of the neustonic larval fish assemblage influenced by the oceanographic conditions in the Campos Basin. We recommend to additionally collect night samples to decrease larval escapement rates and to compare night versus day catches to further investigate the influence of daily migration in the neustonic larval fish in the area.

A morphological revision is presented here on the cohort Otomorpha, a clade currently interpreted as the most primitive among the large supercohort Clupeocephala. Otomorpha is a morphologically heterogeneous group represented by clupei forms , alepocephaliforms, and ostariophysans (gonorynchiforms, cypriniforms, characiforms, siluriforms, and gymnoti forms) that inhabit various marine and freshwater environments worldwide. Otomorphs have a long (ca. 145 Ma) and diverse fossil record. They are the largest fish teleostean clade worldwide, as well as the largest of the Neotropical Region. While molecular studies strongly confirm the monophyly of Otomorpha, most potential morphological synapomorphies of the group become homoplastic largely due to the peculiar morphological character states (either losses or transformations) present in alepocephaliforms. The fusion of haemal arches with their respective vertebral centra anterior to preural centrum 2 stands as an unambiguous synapomorphy of the clade. The ankylosis or fusion of the extrascapular and parietal bones, and silvery areas associated with the gas bladder are also interpreted as synapomorphies, although they are homoplastic characters mainly due to secondary losses or further transformations of the morphological features in the alepocephaliforms.
... Sardinella lemuru, belonging to Clupeinae, Clupeidae, Clupeoidei, Clupeiformes (Whitehead 1985;Nelson 2006), is an economically important species (Pedrosa-Gerasmio et al. 2015). It is distributed in the coastal water of China and the shallow sea of the western Pacific (Chen 2015). ...
The complete mitochondrial genome of Sardinella lemuru was sequenced using PCR amplification and primer walking sequence method. The complete mitochondrial genome of S. lemuru was 16,616 bp and contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region (D-loop). The overall base composition was A 25.04%, C 29.36%, G 20.40%, T 25.20%. In this study, the gene arrangement was consistent with other Sardinella mitochondrial genomes. Additionally, the phylogenetic relationships of 23 Clupeoidei species based on the complete genome was analyzed, and the result showed that S. lemuru firstly clustered with other two Sardinella species, S. albella and S. maderensis. These results would be useful for the investigation of phylogenetic relationship, taxonomic classification and phylogeography of the Clupeoidei.
... Among these sardine species is the Sardinella tawilis, also regarded as the only freshwater Sardinella species known worldwide (Whitehead 1985). It is endemic to Taal Lake, the third largest lake in the Philippines. ...
The only freshwater Sardinella, Sardinella tawilis (Herre 1927), endemic to Taal Lake, Philippines, continues to be an important food commodity and serves as a piece of cultural heritage within the country. However, the early life history of this species is unknown. In the present study, identification of the S. tawilis larvae has been finally confirmed through the utilization of the DNA barcode marker cytochrome c oxidase I (CO1) gene and the Kimura 2-parameter (K2P) distance model. Results showed 100% identity of three larvae samples with S. tawilis GenBank reference sequences based on clustering analysis, which was supported by mean genetic distance of 1%, suggesting accurate identification of the larvae samples. Subsequently, the larval developmental stages in pre-flexion, flexion, post-flexion and juvenile stage of S. tawilis were described and illustrated. Morphological analyses revealed that the larvae had elongated and straight gut with budding pectoral fin during pre-flexion stage, disappearance of fin-fold on the flexion stage, growth of fin rays during post-flexion stage and well developed fins in juvenile stage. This study serves as the first report on the identification of S. tawilis larvae as well as its morphological description during larval development.
... In this estuary, the larval fish assemblage was highly dominated by a single species A. lepidentostole. It is an anadromous species with wider distribution (Western Central and South Atlantic) that migrates to the interior of the rivers for spawning (Whitehead et al., 1988). Previous studies verified that its entrance in the river for reproduction depends on climatic factors, especially temperature (Giamas et al., 1983;Paiva-Filho et al., 1986;Souza et al., 1988;Ribeiro et al., 2014). ...

La compréhension de la connectivité entre les nourriceries estuariennes et les habitats marins est fondamentale pour l'étude de la dynamique des peuplements et des populations de poissons et pour la conception de stratégies efficaces de conservation et de gestion des pêches. Le but de ce travail était donc de fournir une première référence faunistique et écologique des poissons des estuaires et du lagon de l'île de Socotra (Nord-Ouest de l'Océan Indien) pour les gestionnaires de la zone côtière, avec un accent particulier sur le fonctionnement des populations d'une espèce sentinelle: Terapon jarbua. Dans cette étude, une approche multidisciplinaire a été développée afin de comprendre le fonctionnement et l'importance des estuaires (TOCE's : Temporarily Open / Closed Estuaries) et du lagon de l'île de Socotra pour les poissons marins. Différents outils de la biologie et de la chimie (taxonomie, écologie, phylogéographie, génétique des populations, microstructure et microchimie des otolithes) ont été utilisés et les principales conclusions de ce travail sont les suivantes: 1) Les estuaires de Socotra sont composés de 64 espèces dans 30 familles, un chiffre élevé par rapport aux normes régionales. La comparaison avec les inventaires faunistiques d'Afrique du Sud et du Yémen suggère que Socotra joue le rôle de tremplin biogéographique, en permettant la connexion d'une grande variété de groupes taxonomiques provenant de différentes unités biogéographiques. De plus 33 des 64 espèces recensées sont considérées comme importantes pour l'économie locale, soulignant l'importance primordiale des estuaires comme sites de fraie et nourriceries, pour le fonctionnement durable des services écosystémiques. 2) La phylogéographie et la structure génétique des populations de T. jarbua ont été analysées considérant des marqueurs de type Cytochrome c Oxydase sous-unité I et microsatellites. Une différenciation génétique élevée et significative a été observée à l'échelle de l'Indo-Ouest Pacifique. Trois groupes de populations ont pu être identifiés, le groupe du Nord-Ouest de l'Océan Indien (Socotra, Yémen et Iran), le groupe de l'Ouest de l'Inde et le groupe de la Mer de Chine. Cependant, les grandes différences nucléotidiques observées soulèvent certaines questions concernant l'identification de l'espèce et suggèrent que T. jarbua pourrait être en réalité un complexe d'espèces, en dépit du fait que la coloration caractéristique de T. jarbua facilite son identification. A l'échelle plus restreinte du Nord-Ouest de l'Océan Indien, une expansion récente de la population de T. jarbua après des extinctions locales au cours des glaciations du Pléistocène pourrait expliquer la faible mais significative différenciation génétique. Le génotypage des marqueurs microsatellites souligne une différenciation génétique relativement élevée et significative entre les estuaires, sur le secteur Socotra-Yémen. Si la distance géographique n'est pas un facteur structurant majeur des populations de T. jarbua dans la région du Golfe d'Aden, le lien étroit entre les juvéniles T. jarbua et les TOCE, ainsi que les phénomènes d'ouverture associés à de possibles goulots d'étranglement démographiques dans ces systèmes côtiers, peuvent expliquer la mise en place d'une différenciation génétique locale significative entre les estuaires. Bien que l'environnement dynamique de la région puisse limiter la différenciation génétique, la courte durée du stade larvaire de cette espèce (25 jours estimés par la lecture des microstructures de l'otolithe) et la possible rétention des larves dans certains secteurs peuvent réduire l'homogénéisation à plus grande échelle géographique. 3) Les analyses de la composition élémentaire des nucleus d'otolithes suggèrent l'existence de plusieurs zones de fraie marines ; ces données confrontées aux résultats des investigations en génétique des populations suggèrent un modèle régional de métapopulation composée de sous-populations ouvertes…

Marking and tagging is a widely used method for studying wild populations. The idea is simply to label a number of objects such as fish. Thus, we can obtain lots of knowledges about population parameters: densities, mortality rates, recruitment, age and growth, movements, migrations and mixing of stocks, behavioral and physiological studies (telemetry) etc. The aim of this review is describe of marking-tagging materials and methods and to introduce of marking objects.

... Thryssa kammalensis, which belongs to order Clupeiformes, family Engraulidae, genus Thryssa is a warm-temperature species. It is mainly distributed along the coasts of Indo-West Pacific Ocean, as well as also common in China (Whitehead et al. 1988). There are few specific genetic research about T. kammalensis, only some phylogenetic studies involved T. kammalensis (Ma et al. 2010;Bloom and Lovejoy 2012). ...
In this study, the complete mitochondrial genome (mitogenome) sequence of Thryssa kammalensis has been determined by long polymerase chain reaction and primer walking methods. The mitogenome is a circular molecule of 16 968 bp in length and contains 37 mitochondrial genes including 13 protein-coding genes, two ribosomal RNA (rRNA), 22 transfer RNA (tRNA) and a control region as other bony fishes. Within the control region, we identified the termination-associated sequence (TAS) domain, the central conserved sequence block domains (CSB-F, CSB-E and CSB-D) and the conserved sequence block domains (CSB-1, CSB-2 and CSB-3). There are eight copies of tandem repeats of 38 bp in the control region, which contain TAS.

Abstract In this study, the complete mitochondrial genome (mitogenome) sequence of Coilia grayii has been determined by long polymerase chain reaction and primer walking methods. The mitogenome is a circular molecule of 16,851 bp in length and contains 37 mitochondrial genes including 13 protein-coding genes, 2 ribosomal RNA (rRNA), 22 transfer RNAs (tRNAs) and a control region as other bony fishes. Within the control region, we identified the termination-associated sequence domain (TAS), the central conserved sequence block domains (CSB-F, CSB-E and CSB-D), and the conserved sequence block domains (CSB-1, CSB-2 and CSB-3).
... There are 5 genera and 12 species of engraulids in the coastal waters of Taiwan are revised (Young et al., 1994). Species of adult engraulids are classified mainly based on the numbers of pre-or post-pelvic scutes (Shen, 1984;Chen and Yu, 1986;Whitehead et al., 1988;Nakabo, 1993;Shen et al., 1993;Young et al., 1994). However, these characters are lacking in larvae and thus not applicable to the larval stage of engraulids. ...
Five species of larval engraulids, Engraulis japonica Schlegel, Encrasicholina punctifer Fowler, E. heteroloba (Ruppell), Stolephorus insularis Hardenberg, and Thryssa dussumieri (Valenciennes), were found in coastal waters off the Tanshui River Estuary, northern Taiwan during the period from May 1992 through November 1993. Their sizes ranged between 8 and 46 mm SL. Comparing the meristics, morphometrics, and pigmentations of the 5 species, we found pigment patterns on the ventral side of the larvae that can be used as a key character to discriminate these species.

In marine fish species, dispersal or migrations are known to be the principal forces responsible in minimizing population structure. Anadromous species show distinct genetical patterns linked to their specific reproductive behaviour. However, little is known about species that are marine spawners but use estuaries and freshwater as nurseries, such as Terapon jarbua, which is thought to be estuarine dependent and to form panmictic populations at a larger geographical scale. Nevertheless, patterns of hyposaline habitat use, larval homing behaviour, and site fidelity are considered to have the potential to separate populations or subpopulations. This study aims to understand the population structure of T. jarbua inhabiting coastal estuaries on Socotra island and the Yemen mainland, and to describe the associated fish communities and their ecology. Several hypotheses will be tested to demonstrate: 1) that T. jarbua is not an obligate user of estuaries but rather an “amphidromous” opportunistic species with regard to its use of coastal hyposaline habitats as nursery; 2) that T. jarbua forms a panmictic population between Socotra Island and South Yemen mainland, and, if this hypothesis is rejected; 3) that T. jarbua forms a panmictic population across the different estuarine habitats of Socotra Island. Inferred from otolith microchemistry, ”strains” that are geographically linked to distinct spawning and nursery habitats, are established to determine patterns and scales of connectivity between subpopulations living in hyposaline and marine habitats at different life stages (migrations, larval and mature stages, and spawning periods). The identity of the strains previously determined is tested by assessing the genetic differentiation between such strains using mitochondrial and microsatellite DNA variability and phenotypic characters.

Understanding connectivity between estuarine nurseries and marine habitats is fundamental to explore fish population dynamics and to the design of effective conservation and fisheries management strategies. The aim of this work was to provide the first faunistic and ecological baseline of Socotra Island (North-Western Indian Ocean) estuaries and lagoon fishes for governmental coastal managers and decision makers, with a particular focus on the population functioning of a sentinel species: Terapon jarbua. In this study, a multidisciplinary approach was developed to understand the functioning and importance of Socotra estuaries (TOCE's: Temporarily Open / Close Estuaries) and lagoons for marine fishes. Several biological and chemical tools (taxonomy, ecology, phylogenetics, population genetics, otolith microstructure, otolith microchemistry) were used and the main findings of this work are as follows: 1) Socotra estuaries are composed of 64 species in 30 families, a high figure by regional standards. The comparison with faunistic records from South Africa and Yemen mainland provides further support to Socotra's function as a biogeographic "stepping stone" for certain species. Moreover 33 out of the 64 recorded species were considered as relevant species for the local economy. This underscores the paramount importance of these coastal water bodies as spawning and nursery sites and for the sustainability of vital provisioning ecosystem services. 2) The phylogeography and the genetic structure of T. jarbua populations were analyzed considering Cytochrome c Oxidase subunit I and microsatellites and underlined two patterns of genetic structure. A high and significant genetic differentiation was observed at the scale of the Indo-West Pacific. Three population clusters could be drawn, the North-Western Indian Ocean cluster (Socotra, Yemen and Iran), the West Indian Shelf cluster and the Chinese Sea cluster. However, the large number of nucleotide differences raised some issues concerning the species identification as T. jarbua might be a species complex, despite the fact that it shows a characteristic color pattern easily identifiable. At the restricted scale of the North-Western Indian Ocean, recent population expansion after local extinctions during the Pleistocene glaciations might explain small but significant genetic differentiation. Considering microsatellites, genotyping highlighted a relatively high and significant genetic differentiation between estuaries, over the Socotra-Yemen region. Geographical distance is not a major structuring factor for T. jarbua populations in the wider Gulf of Aden region. The strict link between juvenile T. jarbua and TOCE's, and the opening/closing associated with possible demographic bottlenecks, could increase the local differentiation among estuaries. Although the dynamic environment of the region driven by the monsoon system could reduce the genetic differentiation between populations, the short larval stage duration (25 days estimated by otolith microstructure readings) and potential larval retention in particular sectors might reduce homogenization over larger geographical scale. 3) The analysis of otolith nucleus elemental composition suggested the existence of several marine spawning grounds, thus confirming the population genetics approach suggesting a regional model of metapopulation composed of open subpopulations (i.e. multiple sources and more or less pronounced mixtures of larval flows displaying a spatio-temporal variability). In addition, transect Sr:Ba ratio analysis along the otolith growth axis showed clear pattern of post larval migrations into estuarine nurseries where individuals remain for two years. Finally, otolith edges elemental fingerprint assignation tests to nurseries were highly accurate and could conduct in the future to the assessment of the contribution level of a particular nursery to the adult population of T. jarbua as well as others ecologically or economically important species.
... The grenadier anchovy Coilia nasus in the family Engraulidae is a coastal, estuarine, and freshwater species. This species is distributed widely throughout the western coastal waters of Korea and the Ariake Sound of southwestern Japan, as well as the middle and lower reaches of the Yangtze River, the East Sea, and the Yellow Sea of China (Whitehead et al., 1988). Within its distribution, C. nasus exhibits remarkable diversity in terms of morphology, ecology, and behavior. ...
Coilia nasus is found in the Yangtze River and the coastal waters of China, Korea, and Japan. Two ecotypes (anadromous and freshwater-resident populations) are distributed throughout the Yangtze River basin based on their ecology and behavior, but relatively little is known about the population structure of this species. Analysis of short interspersed element (SINE) insertions, which vary among individuals, has been acknowledged to provide a unique way to study population divergence. SINEs isolated from C. nasus were characterized, and this enabled analysis of the SINE insertion pattern in six populations distributed throughout the Yangtze River basin. In all populations, four SINE loci displayed individual polymorphism, and two SINE loci showed a stochastic loss in all individuals of two resident populations. The correlation between genetic and geographic populations indicated a degree of genetic isolation in this species. In contrast with Coilia grayii and Coilia mystus, two SINE loci appeared only in C. nasus. Sequencing analysis indicated that the high insertion variability of SINEs was attributed mainly to the tails, which contained various repeat copies. The results in this study will be useful for sustainable management of fishery resources and conservation of this species.
... aceans. Because the ability to detect US has been found only in the Alosinae, and not in the closely related Clupeinae, the question becomes: When did the Alosinae evolve? Based on hypothesized phylogeny for Alosinae it was around the same time as the evolution of the echolocating river dolphins (Hamilton et al., 2001;Lavoué et al., 2007) (Fig. 6).Whitehead et al., 1985). Y ¼ number of species with positive responses to US; N, number of species tested that failed to respond to US It is therefore tempting to envision that US detection arose in the Alosinae in response to predation from echolocating river dolphins.

The frequency range of hearing in fishes and frogs historically has been thought to be confined to relatively low frequencies in comparison to that of mammals. However, within the last 20 years, the audiograms of several fish and frog species have been shown to encompass ultrasonic (US) frequencies. Moreover, these animals have been shown to respond behaviorally to US playbacks. Although the evolution of US detection in these species is still an ongoing topic of study, both fishes and frogs have faced the challenge of producing very high-frequency responses from systems that evolved with low-frequency sensitivity. A short history of the behavioral responses and the electrophysiological mechanisms (when known) underlying the production and reception of US in fishes and frogs is presented, with a focus on the unique experimental approaches that have yielded this surprising upward extension of the hearing ranges of several specialized fishes and frogs.
This study examines the price volatility transmission of fresh anchovies (Engraulis encrasicolus) among different markets along the value chain in Spain. For this purpose, the prices in the first-hand sale, wholesale, and retail markets are considered. A vector autoregressive (VAR) model and an asymmetric multivariate generalised autoregressive conditional heteroskedasticity (MGARCH) model are used to analyse the relationship of price volatility among the markets in the value chain. The results indicate that the retail market has the lowest volatility. Therefore, volatility in the first-hand sale and wholesale markets is only minimally transmitted to consumers. Finally, asymmetric effects are observed in the price volatility transmission along the fresh anchovy value chain.
Coilia brachygnathus is the only one freshwater fish of the genus Coilia in China. In this study, we determined the complete mitochondrial genome of Coilia brachygnathus from Chaohu Lake. It is 16,896 bp in length and consists of 13 protein-coding genes, 2 rRNA genes, 22 transfer RNA genes as well as a control region (CR). Over base composition of the mitogenome is A(31.2%), C(27.0%), T(26.3%), and G(15.5%), respectively. Phylogenetic analysis confirmed the evolutionary relatedness of C. brachygnathus to other fishes of genus Coilia and also revealed the phylogenetic relationship of this genus within Engraulidae at molecular levels.
In this study, the complete mitochondrial genome (mitogenome) sequence of Thryssa dussumieri was determined by long polymerase chain reaction and primer walking methods. The mitogenome was a circular molecule of 16,883 base pairs (bp) in length and contained 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA), 22 transfer RNA (tRNA), and a control region similar to those found in other bony fishes. The overall nucleotide composition was estimated to be 32.1% A, 26.1% C, 23.7% T, and 18.1% G. The neighbor-joining tree was reconstructed based on the 13 PCGs sequences of T. dussumieri and other 10 Engraulidae species. The mitogenome data will provide useful information for further studies on the phylogenetic analysis and population genetics.
This book describes you the taxonomical identification of Clupeiformes fishes of
Southeast coast of India. Nagapattinam, Puducherry fishing harbors and Parangipettai
fish landing centre, was the places mainly concentrated for the sample collcetion. A total
of 56 species of Clupeiformes fishes belonging to 19 genera and 4 families were
identified during January 2008 to December 2009. The order Clupeiformes comprised
four families namely Clupeidae, Engraulidae, Pristigasteridae and Chirocentridae. The
family Clupeidae was represented by 30 species belonging to twelve genera. The family
Engraulidae was represented by 17 species belonging to four genera. The family
Pristigasteridae was represented by 7 species belonging to two genera. The family
Chirocentridae was poorly represented at all the three stations by only 2 species
belonging to single genera.
A clear detailed study on the description of the order Clupeiformes and family
chirocentridae, key characters clupeoid families and clupeoid genera were given for
trouble-free identification.
Vivid pictographic representation with Classification, distribution and statistical
analysis (mean, median, mode, standard deviation, and standard error) were described
and demonstrated on the basis of adequate samples and morphometric and meristic
characters of all the 56 species were explained using the key of Whitehead (1985).
The habitat use and life history characteristics of the estuarine tapertail anchovy, Coilia nasus from Qiantang River were studied by examining the environmental signatures of Sr and Ca in otoliths using otolith microchemical analysis. The results indicate the C. nasus in the present study could be briefly divided into three types: Types 1/Type 2 of riverine origin and initial relative long-term/short-term freshwater residence, and Types 3 of estuarine origin and initial brackish early life history. The availability and fluctuation of certain levels of Sr:Ca ratios (i.e., Sr:Ca×1000) between salinity scale of 3.00 and 7.00 reveal that the C. nasus analyzed in this study spent much more time in brackish habitat of the river's estuary. This study has established that the C. nasus of Qiantang River Estuary has a diverse and complex pattern of life history and habitat use which makes their life history and migration pattern vary from those of the Yangtze River.
The Coilia nasus is an important fish species, which is of commercial values in China. In order to manage the fisheries resources and the development of sustainable fishing strategies to protect this species, 11 microsatellite loci polymorphisms and mtDNA COI sequences were used to examine the genetic diversity of C. nasus in Japan and China. In total, the 40 COI haplotypes and 93 microsatellite alleles were detected. The mtDNA phylogeny did not support population grouping, but the distribution patterns of mtDNA haplotypes and the results of STRUCTURE analysis based on microsatellite indicated a degree of genetic isolation in this species. Our study suggested that the lack of a population genetic structure might result in its amphidromous life cycle, and the geographical distance and habitat fragments might cause isolated populations. Thus, the sampling populations of C. nasus in Japan and China could be divided as four geographical/ecological populations.
Detecting and estimating the degree of genetic differentiation among populations of highly mobile marine fish having pelagic larval stages is challenging because their effective population sizes can be large, and thus, little genetic drift and differentiation is expected in neutral genomic sites. However, genomic sites subject to directional selection stemming from variation in local environmental conditions can still show substantial genetic differentiation, yet these signatures can be hard to detect with low-throughput approaches. Using a pooled RAD-seq approach we investigated genome-wide patterns of genetic variability and differentiation within and among 20 populations of Atlantic herring in the Baltic Sea (and adjacent Atlantic sites), where previous low-throughput studies and/or studies based on few populations have found limited evidence for genetic differentiation. Stringent quality control was applied in the filtering of 1 791 254 SNPs, resulting in a final dataset of 68 182 polymorphic loci. Clear differentiation was identified between Atlantic and Baltic populations in many genomic sites, while differentiation within the Baltic Sea area was weaker and geographically less structured. However, outlier analyses - whether including all populations or only those within the Baltic Sea - uncovered hundreds of directionally selected loci in which variability was associated with either salinity, temperature, or both. Hence, our results support the view that although the degree of genetic differentiation among Baltic Sea herring populations is low, there are many genomic regions showing elevated divergence, apparently as a response to temperature- and salinity-related natural selection. As such, the results add to the increasing evidence of local adaptation in highly mobile marine organisms, and those in the young Baltic Sea in particular. This article is protected by copyright.

The gizzard shad, Konosirus punctatus, is one of the most important fish species in Korea, China, Japan and Taiwan, and therefore the implementation of an appropriate population structure analysis is both necessary and fitting. In order to clarify the current distribution range for the two lineages of the Korean gizzard shad (Myoung and Kim 2014), we conducted a multivariate morphometric analysis by locality and lineage. We analyzed 17 morphometric and 5 meristic characters of 173 individuals, which were sampled from eight localities in the East Sea, the Yellow Sea and the Korean Strait. Unlike population genetics studies, the canonical discriminant analysis (CDA) results showed that the two morphotypes were clearly segregated by the center value “0” of CAN1, of which morphotype A occurred from the Yellow Sea to the western Korean Strait with negative values, and morphotype B occurred from the East Sea to the eastern Korean Strait with positive values even though there exists an admixture zone in the eastern Korean Strait. Further studies using more sensitive markers such as microsatellite DNA are required in order to define the true relationship between the two lineages.
Este livro foi concebido com o objetivo de apresentar de forma sumária a fauna de peixes e camarões encontrados mais freqüentemente no sistema estuarino-fluvial do rio Caeté, no litoral do estado do Pará.
O trabalho de campo e a compilação de dados foram realizados com o apoio do Programa MADAM-Manejo e Dinâmica de Áreas de Manguezais, que é uma iniciativa de cooperação científica entre a Universidade Federal do Pará, pelo Brasil, e o Centro de Ecologia Marinha Tropical de Bremen, pela Alemanha, sendo apoiado pelo CNPq-Conselho Nacional de Desenvolvimento Científico e Tecnológico e pelo BMBF-Ministério Alemão de Educação e Pesquisa.
Este é o primeiro manual do gênero para a região, e visa servir como guia para futuros trabalhos científicos e, ao mesmo tempo, como um instrumento de divulgação da diversidade biológica da fauna aquática junto aos moradores da região, pescadores, estudantes, gestores e outros interessados.
Stable isotopes are increasingly used to investigate seasonal migrations of aquatic organisms. This study employed stable isotopes (δ13C and δ15N) for Coilia nasus from the lower Yangtze River and the adjacent East China Sea to distinguish different ecotypic groups, ascertain trophic nutrition positions, and reflect environmental influences on C. nasus. δ13C signatures of C. nasus sampled from Zhoushan (ZS), Chongming (CM), and Jingjiang (JJ) waters were significantly higher than those from the Poyang Lake (PYL) (P < 0.05). By contrast, δ15N signatures of C. nasus in ZS, CM, and JJ groups were significantly lower than those in PYL group (P < 0.05). Basing on δ13C and δ15N signatures, we could distinguish anadromous (ZS, CM, and JJ) and non-anadromous (PYL) groups. The trophic level (TL) of anadromous C. nasus ranged from 2.90 to 3.04, whereas that of non-anadromous C. nasus was 4.38. C. nasus occupied the middle and top nutrition positions in the marine and Poyang Lake food webs, respectively. C. nasus in Poyang Lake were significantly more enriched in δ15N but depleted in δ13C, suggesting that anthropogenic nutrient inputs and terrigenous organic carbon are important to the Poyang Lake food web. This study is the first to apply δ15N and δ13C to population assignment studies of C. nasus in the Yangtze River and its affiliated waters. Analysis of stable isotopes (δ15N and δ13C) is shown to be a useful tool for discriminating anadromous and non-anadromous C. nasus. © 2015, Science Press, Ocean University of China and Springer-Verlag Berlin Heidelberg.
Small pelagic fish species present complex dynamics that challenge population biologists and prevent effective management. Huge fluctuations in abundance have been traditionally associated with external environmental forcing on recruitment, exempting other processes from contributing to fisheries collapse. On the other hand, theory predicts that density dependence and overexploitation can increase the likelihood of population oscillations. Here, we combined nonlinear population modeling with Bayesian analysis to examine the importance of different regulatory mechanisms on the collapse of European anchovy (Engraulis encrasicolus) in the Bay of Biscay. The approach relied on detailed population data and in a careful characterization of changes in the environment experienced by anchovy early stages based mainly on satellite remote sensing. Alternative hypotheses about external forcing on recruitment determined prediction skill and provided alternative interpretations of the causes behind the collapse. Density dependence was weak and unable to generate huge oscillations. Instead, models considering changes in phytoplankton phenology or in larval drift presented the best prediction skill. Nevertheless, an extensive surrogate analysis showed that environmental fluctuations alone barely explain anchovy collapse without considering the impact of fishing. Our results highlight the effectiveness of a Bayesian approach to analyze the dynamics and collapse of managed populations.

Efficiency of the identification of eggs of Engraulis anchoita can be greatly improved by a method developed from egg measurements, using photography and the ImageJ programme, analysed by discriminant analysis using R software.
Abstract In this study, the complete mitochondrial genome (mitogenome) sequence of Coilia nasus has been determined by long polymerase chain reaction and primer walking methods. The mitogenome is a circular molecule of 16,896 bp in length and contains 37 mitochondrial genes including 13 protein-coding genes, 2 ribosomal RNA (rRNA), 22 transfer RNA (tRNA) and a control region as other bony fishes. Within the control region, we identified the termination-associated sequence domain (TAS), the central conserved sequence block domains (CSB-F, CSB-E and CSB-D), and the conserved sequence block domains (CSB-1, CSB-2 and CSB-3).
