Assessment Information
Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2021
Date Assessed: November 13, 2019
Justification:
This species is widespread and relatively common throughout the Indo-West Pacific. It is utilized
commercially and is a common component of demersal fishery by-catch in some parts of its range. It is
also utilized in aquaculture. There are no known major threats. There is a stock recovery plan for this
species initiated by the Ministry of Ocean and Fisheries of Korea, but there are no reports on its
effectiveness. There are several marine protected areas that overlap with its distribution. Therefore,
Muraenesox cinereus is listed as Least Concern.
Geographic Range
Range Description:
This species is widespread in the Indo-West Pacific, from East Africa, Madagascar, and the Red Sea east
to Tuvalu and Fiji north to China, Japan, and Republic of Korea and south to the Arafura Sea and
northern Australia, including the Persian Gulf, India, the Mariana Islands, the Philippines, Malaysia, the
Gulf of Thailand, and throughout the East Indian region (Motomura et al. 2017, Golani and Fricke 2018,
Fricke et al. 2018, Eagderi et al. 2019; Accessed through the Fishnet2 Portal, www.fishnet2.org). It has
invaded the Mediterranean from the Red Sea via the Suez Canal (Golani and Ben-Tuvia 1982, Eagderi et
al. 2019). It occurs at depths of 300-800 metres (Goldshmidt et al. 1996).

Population
This species is described as "common" and "moderately abundant" in many parts of its range
(Motomura et al. 2017). Globally, landings of this species have increased substantially. In 1950, 21,000
tonnes were reportedly landed, but by 2017, over 340,000 tonnes were reported landed, over 90% of
which were landed in China (FishStatJ database accessed 10 July 2019). In Republic of Korea, catches
have declined in recent years, from 3,760 metric tonnes in 1993 to 1,650 tonnes in 2009 and 862 tonnes
in 2013; however, Japan has increased its landings of this species to record highs of 812 tonnes (Watari
et al. 2013, Ji et al. 2015). It is unknown how the population of this species is affected by this use, and
the global population status of this species is unknown.
Current Population Trend:ÊÊUnknown
Habitat and Ecology (see Appendix for additional information)
This demersal, oceanodromous species occurs in brackish waters and marine waters in tropical to
subtropical shallow-water, benthic habitats over soft bottoms in estuaries, lagoons and shallow, coastal
inlets (Fricke et al. 2018, Psomadakis et al. 2020). It also inhabits coral reefs (Nguyen and Nguyen 2006).
It feeds on small, benthic fishes and crustaceans (Ji et al. 2015). Spawning season for this species occurs
between June and August, with a peak in July (Kobayashi et al. 2015). The maximum recorded total
length for this species is 220 cm, but it is more often encountered at 80.0 cm (Masuda et al. 1984). The
maximum reported age for this species is 15 years (Altman and Dittmer 1962).
Systems:ÊÊFreshwater (=Inland waters), Marine
Use and Trade
This species is an important commercial demersal stock in many parts of its range, including Myanmar,
China, Republic of Korea and Japan; it is mainly taken with long-lines at night, as well as bag nets. It is
marketed fresh or used as bait for shark fishing (Bianchi 1985, Smith 1999, Ji et al. 2015, Psomadakis et
al. 2020). It is also considered medicinal in China (Tang 1987). In Japan this species is also farmed,
although the quantity is unknown (Masuda et al. 1984).
Threats (see Appendix for additional information)
This species is often included in the discarded bycatch from the Kuwait Shrimp Fishery with >1 kg
relative abundance during the shrimp season from September 2010 to January 2011 (Chen et al. 2013).
It has also been recorded as a component of the Shrimp Trawl Fisheries in Bushehr coastal waters in the
northern Persian Gulf. This species contributed 43.494 kg total weight, 0.263% of total catch in 2001,
with a 0.418 kg/h catch per unit effort (CPUE). It contributed 42.876 kg total weight, 0.325% of total
catch in 2002, with a 0.275 CPUE in kg/h (Paighambari and Daliri 2012). Additionally, this species is a
component of the bycatch in the Persian Gulf Cutlassfish Trawl Fishery where it represents 20% of the
occurrences in Hormozgan and 17% of the occurrences in Bushehr; it only represented a small weight
percent of total by-catch (<0.5) in both locations (Hosseini et al. 2012).
Conservation Actions (see Appendix for additional information)
There are no species-specific conservation measures for this species, although there are a number of
marine protected areas within its geographic range, such as the Palau National Marine Sanctuary.

... If established in the northern Gulf of Mexico in high densities, then the highly predatory feeding behavior, including prey naiveté of Scorpaenidae (sensu Anton et al. 2014), may lead to declines in native reef fishes and forage species like that seen in the lionfish invasion. Muraenesox cinereus was the only very high-risk fish species that is not within the Scorpaenidae, but it is known to exploit resources by opportunistic predation on a wide variety of small-bodied fishes and crustaceans (McCosker et al. 2021). ...

Prevention of non-native species introductions and establishment is essential to avoid adverse impacts of invasive species in marine environments. To identify potential new invasive species and inform non-native species management options for the northern Gulf of Mexico (Alabama, Mississippi, Louisiana, Texas), 138 marine species were risk screened for current and future climate conditions using the Aquatic Species Invasiveness Screening Kit. Species were risk-ranked as low, medium, high, and very high risk based on separate (calibrated) thresholds for fishes, tunicates, and invertebrates. In the basic screening, 15 fishes, two tunicates, and 26 invertebrates were classified as high or very high risk under current climate conditions. Whereas, under future climate conditions, 16 fishes, three tunicates, and 33 invertebrates were classified as high or very high risk. Very high risk species included: California scorpionfish Scorpaena guttata, red scorpionfish Scorpaena scrofa, purple whelk Rapana venosa, and Santo Domingo false mussel Mytilopsis sallei under both current and future climates, with weedy scorpionfish Rhinopias frondosa, Papuan scorpionfish Scorpaenopsis papuensis, daggertooth pike conger Muraenesox cinereus, yellowfin scorpionfish Scorpaenopsis neglecta, tassled scorpionfish Scorpaenopsis oxycephalus, brush-clawed shore crab Hemigrapsus takanoi, honeycomb oyster Hyotissa hyotis, carinate rock shell Indothais lacera, and Asian green mussel Perna viridis under climate change conditions only. This study provides evidence to inform trans-boundary management plans across the five Gulf of Mexico states to prevent, detect, and respond rapidly to new species arrivals.
... In a previous study, no captive-reared larvae of pike conger were found to strike at foods such as Chlorella, rotifers, Protozoa, fertilized eggs of sea urchin and phytoplankton [53]. However, pike conger of larger size is an active predator feeding on the bathypelagic-pelagic, demersal and small bottom living organisms including fishes, crustaceans and cephalopods [54][55][56]. The stomach content of pike congers collected from Porto-Novo, West Africa, was found to be predominantly composed of mackerel, Clupeids, Caranx species, squids and flying fish [57]. ...

Background The genus Huffmanela Moravec, 1987 (Nematoda, Trichosomoididae, Huffmanelinae), represents a group of nematodes that infect both marine and freshwater fish, and the main gross feature of infection with different species of the genus is the presence of noticeable dark spots or tracks within the parasitized tissues. The purpose of this study was to describe morphologically and morphometrically the eggs of a new marine species of Huffmanela (Huffmanela persica sp. nov.), which was found in the form of black spots in the ovary and the tunica serosa of the stomach of the daggertooth pike conger (Muraenesox cinereus). The new species differs from Huffmanela hamo, another species reported from musculature of this host in Japan, in egg metrics, eggshell features and targeted organ. Molecular identification and pathological examination of the lesions caused by the new species are also reported. Methods Nematode eggs with varying degrees of development were separated from the infected tissues (ovary and tunica serosa of stomach) and investigated using light and scanning electron microscopy. Different species-specific markers (small subunit ribosomal DNA, 18S; large subunit ribosomal DNA, 28S; internal transcribed spacer, ITS) were used for molecular identification and phylogenetic study of the new species. Infected tissues were fixed in buffered formalin for pathological investigations. Results The fully developed eggs of H. persica sp. nov. are distinguished from those previously described from this host on the basis of their measurements (size, 54–68 × 31–43 µm; polar plugs, 6.4–9.7 × 8.4–12 µm; shell thickness, 3.5–6.1 µm) and a delicate but ornate uterine layer (UL) covering the entire eggshell including the polar plugs. Histopathological examination revealed a fibro-granulomatous inflammation in the ovary and the serosal layer of the stomach of infected fish. Maximum-likelihood (ML) phylogenetic analysis recovered a sister relationship between the new species of marine origin and Huffmanela species previously collected from freshwater hosts. Conclusions The present study is the first to report the molecular characterization and phylogenetic position of a teleost-associated marine species of the genus Huffmanela. A comprehensive list of nominal and innominate populations of Huffmanela is also provided. Graphical abstract
... For IUCN to consider a species as endangered must fulfill some prerequisites to classify the taxa facing a very high risk of extinction in near future. The critically high endangered species are known to be nearly 538; however, 1702 species (28% of total evaluated) were considered as data deficient with minimum available information to full assessment and for determining their conservation status [102]. However, IUCN noted them as with the same degree of attention as threatened taxa till their status can be assessed. ...

There are lot of reasons and causes of insect decline. The main causes of insect decline is attributed to habitat destruction, land use changes, deforestation, intensive agriculture, urbanization, pollution, climate change, introduction of invasive insect species, application of pesticides, mass trapping of insects using pheromones and light traps, pathological problems on various insects, and introduction of exotic honey bees in new areas that compete with the native bees for resource portioning and other management techniques for pest management, and even not leaving any pest residue for predators and parasitoids for their survival. The use of chemical insecticides against target or non-target organisms is major cause for insect decline. The diseases and decline of the important pollinators is still a mistry for colony collapse disorder. To overcome the cause of insect decline, various conservation techniques to be adopted and augmentation of artificial nesting and feeding structures, use of green pesticides, maintaining the proper pest defender ratio (P:D), policies and reaching to political audience at global level and other factors already discussed in the chapter may be helpful for mitigating the insect decline and especially for the pollinators, a key insect for life.

Whereas, under future climate conditions, 16 fishes, three tunicates, and 33 invertebrates were classified as high or very high risk. Very high risk species included: California scorpionfish Scorpaena guttata, red scorpionfish Scorpaena scrofa, purple whelk Rapana venosa, and Santo Domingo false mussel Mytilopsis sallie under both current and future climates, with weedy scorpionfish Rhinopias frondosa, Papuan scorpionfish Scorpaenopsis papuensis, daggertooth pike conger Muraenesox cinereus, yellowfin scorpionfish Scorpaenopsis neglecta, tassled scorpionfish Scorpaenopsis oxycephalus, brush-clawed shore crab Hemigrapsus takanoi, honeycomb oyster Hyotissa hyotis, carinate rock shell Indothais lacera, and Asian green mussel Perna viridis under climate change conditions only. This study provides evidence to inform trans-boundary management plans across the five Gulf of Mexico states to prevent, detect, and respond rapidly to new species arrivals.

This checklist aims to reviews and summarize the results of the systematic researches on the Persian Gulf ichthyofauna that has been carried out for more than 200 years. Since the work of C. Niebuhr, a Danish biologist in the 18th century, the number of valid species has increased significantly and the systematic status of many of the species has changed, and reorganization and updating of the published information has become essential. Here we take the opportunity to provide a new and updated checklist of fishes of Persian Gulf based on literature and taxon occurrence data obtained from natural history and new fish collections. The total confirmed fish species of Persian Gulf comprise 744 species, 131 families, 445 genera and 27 orders. In the class Chondrichthyes, the most diverse family is Charcharhinidae with 23 species (41.89%), followed by Dasyatidae with 15 species (31.08%). Within the class Actinopterygii, Gobiidae with 65 species (9.70%), Carangidae with 45 species (6.27%), Serranidae with 25 species (3.73%), Apogonidae with 25 species (3.73%), Lutjanidae with 23 species (3.43%) and Blenniidae with 23 species (3.43%) are the most diverse families in the Persian Gulf.

An annotated checklist of the fish species of the Madagascar EEZ (southwestern Indian Ocean) comprises a total of 1,798 species in 247 families. 158 species are recorded from Madagascar for the first time. The majority of the species is autochthonous; 28 species have been introduced, mainly in freshwater habitats. The fish fauna is mostly marine (95.4% of the total number of native fish species), with the Gobiidae, Labridae, Serranidae, Pomacentridae and Apogonidae being the families with most representatives; among the 90 native freshwater fish species (adults mainly occurring in freshwater), the Cichlidae are the dominating family, but there are also two endemic families, the Bedotiidae (16 species) and Anchariidae (6 species). The fish fauna at Madagascar is typical for offshore, high islands in the southwestern Indian Ocean. Zoogeographically, the main element of the marine fish fauna of Madagascar consists of widespread tropical Indo-Pacific species (978 species, 58.3% of the total native marine species). A total of 13 species (3.3%) are found worldwide, either circumtropical or circumtropical including warm temperate zones. A total of 215 species (12.8%) are widespread in the Indo-West Pacific. An additional 453 species (27.0%) are Indian Ocean endemics, including 233 western Indian Ocean endemics (13.9%), 73 southwestern Indian Ocean endemics (4.4%), 16 species endemic to Madagascar and Mascarenes (1.0%), 4 species endemic to Madagascar and Comoros (0.2%), 3 species endemic to Madagascar and Madagascar Ridge (0.2%), and 37 marine species endemic to Madagascar (2.2%). Most of the autochthonous freshwater fishes are endemic to Madagascar (87 species, 96.7% of the native freshwater species).

The quantity and species compositions of both retained and discarded bycatch of the Kuwait’s shrimp fishery was investigated for the first time directly through onboard observation and sampling of a fishing vessel. The observations were conducted on a 131 tonne double-rigged shrimp trawler twice a month during the shrimp season from September 2010 through January 2011. The shrimp catch rate declined sharply from 19.6 to 1.1 kg/h as the season progressing, while bycatch rate remained in a high and relatively stable between 106 and 81.5 kg/h, and resulted in a large variation (5.4-73.6) of byatch-to-shrimp ratio from the season’s start to the season end. The retained bycatch was always low (11.6-15.9% of the total bycatch) throughout the season. The total species recorded in the bycatch was 112, with 55 retained and 93 discarded at sea. Thirty-nine species occurred both in retained and discarded bycatches. Saurida tumbil, Nematalosa nasus, Sphyraena flavicauda, Acanthopagrus latus and Otolithes ruber were the most dominant fish species in the retained bycatch. Discards dominated both by undersized commercially valuable species including Ilisha melastoma, Pomadasys stridens, Nematalosa nasus, Saurida tumbil and Upeneus doriae, and by non-commercial species such as catfishes, sharks and rays. Based on monthly bycatch-to-shrimp ratio, the percentage of the retained bycatch and the recorded shrimp landings, the total bycatch of Kuwait’s shrimp fishery was estimated to be 15,704 t for the 2010/11 season. Of the total bycatch, only 2192 t (14%) was retained, while the majority 13, 512 t (86%) was discarded at sea. Of the 93 discarded species, 55 are commercially valuable species, representing 61% (8242 t) of the total discarded bycatch.

The current checklist provides for each species of the Red Sea its records in the Gulf of Suez, Gulf of Aqaba, Red Sea main basin and its general distribution.This new checklist of Red Sea fishes enumerates 1207 species, representing 164 families. Of these, 797 species were recorded from the Gulf of Aqaba and 339 from the Gulf of Suez. The number of species from the Gulf of Suez is evidently lower than the actual number not including 27 Lessepsian (Red Sea) migrants to the Mediterranean that most likely occur in the Gulf. The current list includes 73 species that were newly described for science since the last checklist of 2010. The most specious Osteichthyes families are: Gobiidae (134 species), Labridae (66), Apogonidae (59), Serranidae (including Anthiadinae) (44), Blenniidae (42), Carangidae (38), Muraenidae (36), Pomacentridae (35), Syngnathidae (34), Scorpaenidae (24) and Lutjanidae (23). Among the families of Chondrichthyes, the most specious families are the Carcharhinidae (18 species) and Dasyatidae (11). The total number of endemic species in the Red Sea is 174 species, of these, 34 species are endemic to the Gulf of Aqaba and 8 to the Gulf of Suez.

The spatial and temporal variations of finfish bycatch assemblage cutlassfish trawl were compared in two fishing areas (Hormozgan and Bushehr). Data were collected on board of commercial vessels in the fishing grounds of Trichiurus lepturus in Bushehr and Hormozgan marine waters between early May 2010 to late November, 2010. There was a significant difference in the bycatch assemblages between Bushehr and Hormozgan fishing grounds. SIMPER showed that six species contributed as much as 65% of the biomass of the bycatch assemblages between two fishing areas as follows: Nemipterus japonicus (30.5%), Ilisha melastoma (12.5%), Saurida tumbil (8.5%), Argyrops spinifer (6%), Dasyatis bennetti (4.5%) and Arius thalassinus (4%). Differences appeared for the temporal structures of bycatch assemblage in fishing grounds of Bushehr. SIMPER also showed eight species contributed to as much as 69.3% of the dissimilarity of the biomass of the bycatch assemblages between fishing seasons. These species were S. tumbil (17.3%), I. melastoma (16.3%), N. japonicus (13.3%), Carangoides malabaricus (17.2%), Rachycentron canadun (6.3%), Upeneus sundaicus (3.5%) D. bennetti (3.5%) and Epinephelus coioides (3.2%).
