We documented the nearshore ray-finned fishes in Puerto Morelos Reef National Park (PMRNP) by sampling 57 localities, including rocky intertidal pools, sandy bottoms, Thalassia beds, coral reefs, artificial reefs, karstic-slab bottoms, demersal-pelagic areas, and sessile-Sargassum patches. We recorded seven species new to Caribbean Mexican waters and one hundred and six species new to the PMRNP, most of which are small cryptobenthic reef fish. The resultant checklist includes 349 species, and specimens of 285 of which (81.7%) have been deposited in an ichthyological museum collection. These include both voucher organisms and with tissue samples for genetic analysis. A comparison with inventories at other localities of the Greater Caribbean indicates that more targeted sampling for cryptobenthic and deep-reef fishes is needed to provide a complete inventory. We also comment on the local use of some species as fishery resources.

Vázquez J.A. 2016. Spatio-temporal variation in the diet composition of red lionfi sh, Pterois volitans (Actinopterygii: Scorpaeniformes: Scorpaenidae), in the Mexican Caribbean: Insights into the ecological effect of the alien invasion. Acta Ichthyol. Piscat. 46 (3): 185–200. Background. The observed expansion of the red lionfi sh, Pterois volitans (Linnaeus, 1758), in the Caribbean represents one of the most rapid marine fi sh invasions in the history. The invasion rate of this top predator has resulted in a marked negative effect on local fi sh populations in the Caribbean by impacting local biodiversity. The main aim of this work was to conduct the morphological identifi cation of prey items from the lionfi sh diet, and to determine the spatio-temporal variation of the lionfi sh diet composition in different sites of the Mexican Caribbean, to have a better knowledge of how this invasive species is impacting local species of commercial or ecological importance in the region. Materials and methods. The Mexican Caribbean study area was divided in three zones; North (one locality Isla Contoy), Central (three locations Xpu-Ha, Akumal and X'Cacel), and South (two locations Banco Chinchorro and Xcalak). The fi sh were collected, from different habitats, using SCUBA diving and Hawaiian harpoon. Collected fi sh were taxonomically identifi ed, measured for total length (TL) and standard length (SL), and weighed to the nearest gram. Prey items were identifi ed using a dissection microscope. After identifi cation, prey items were separated, counted, and weighted individually. Finally, statistical analyses were made for all the samples using this study database, containing predators and prey items. Results. A total of 76 prey species were identifi ed in 962 lionfi sh stomachs; 47 of them represented fi shes and 29— crustaceans. Fishes of families Pomacentridae, Labridae, and Scaridae were the most abundant diet components of lionfi sh. Rhynchocinetidae, Penaeidae, and Solenoceridae were the most representative Crustaceans families among the prey items. Molluscs were present as diet components only as incidental food. Conclusion. Red lionfi sh, known for its high competitive capacity, preyed more intensively on fi shes than on crustaceans. Therefore, it is evident that the lionfi sh presence in the Mexican Caribbean may affect mainly the local population of reef fi shes. The presently reported results contribute to a better understanding of the red lionfi sh invasion in the Caribbean.

This study is the first to complete an intensive and comprehensive list of the ichthyofauna of nearly all ecosystems of the Michoacán coast, Mexico. The resulting systematic checklist, supplemented with information from the literature and scientific collections, comprises 440 species belonging to two classes, 31 orders, 104 families, and 264 genera. The families with the highest number of species were Sciaenidae (30 spp.), Carangidae (26), Haemulidae (24), Serranidae (21), Paralichthyidae, and Gobiidae (13). Of the total species list, 134 represent first records for the Michoacán State, and one is a first record for Mexico. The results expand the number of known fish species of the Michoacán coast by almost one third and will help to develop conservation and management plans for this coastal zone.

Length–weight (LWR) and standard length–total length (L–L) relations are presented for 14 fish species caught in four estuaries from the southeastern coast of Michoacán, México (Central Pacific): Lile nigrofasciata (Günther, 1862). Values of b ranged from 2.912 to 3.432. The results revealed that length–weight relations for all species were highly correlated; likewise, length–length relations for all fishes also showed high correlation. This study presents for the first time, length–weight parameters for two species and length–length relations for six species.

Se analizó la estructura de la comunidad de peces y se determinaron algunos parámetros fisicoquímicos durante 4 colectas nocturnas en la desembocadura de los estuarios de barra de Nexpa, Teolán, Mexcalhuacán y barra de Pichi, Michoacán, México. Se capturaron un total de 2 014 individuos con un peso de 10 393.42 g, pertenecientes a 31 especies y 20 familias. Barra de Nexpa registró la mayor riqueza con S= 21 y el mayor porcentaje de especies raras con 22.6%. La especies con mayor abundancia fueron Agonostomus monticola y Mugil curema, mientras que Dormitator latifrons y Lutjanus novemfasciatus registraron la mayor biomasa. La salinidad, temperatura, oxígeno disuelto y transparencia mostraron diferencias significativas por temporadas, influidas por la variación estacional de la precipitación. La composición y especies dominantes fueron distintas en cada sitio y en cada temporada, mientras que la abundancia, biomasa y riqueza no mostraron variación significativa. La comunidad de peces estuvo compuesta por especies marinas y dulceacuícolas que utilizan los estuarios como zonas de crianza, especies marinas que se integran al estuario de manera ocasional y especies estuarinas que forman parte de estos ecosistemas durante la mayor parte de su ciclo de vida.

... In the marine environment, the lionfish (Pterois volitans) represents the species with the greatest presence, since it is found in all the protected areas of the northern Yucatan Peninsula and the Mexican Caribbean. Pterois volitans is a threat to the marine ecosystems, mainly for coral reefs [74][75][76][77][78][79] because individuals reproduce fast [74,78], reach high population densities [74,76], consume a wide range of native fish and invertebrate species [75][76][77]79], and can potentially compete for shelter with native species [79]. In addition, the lionfish has economic risks because its diet habits not only include juveniles of commercially important species, such as lobsters, but because it also competes with snappers (Lutjanidae) and groupers (Serranidae) for food and habitat [76]. ...

... They are readily differentiated, however, by their dorsal fi ns – short (seven rays) in armadillo del rio (Figure 1) and longer (10-14 rays) in the sailfi n catfi shes (Figure 2). At least three unknown but " morphologically distinct " species of armadillo del rio and four species of sailfi n catfi shes are established in the United States and Mexico (Page and Burr 1991; Guzmán and Barragán 1997; Nico 1999a Nico , 1999b Nico , 2000a Nico , 2000b; Nico and Fuller 1999; Nico and Martin 2001; Ramirez-Soberon et al. 2004; Wakida-Kusonaki et al. 2007; Sandoval-Huerta et al. 2012).

... En contraste, la captura incidental en este arte au-mentó cuando la temperatura fue menor [característica del área externa de la bahía], lo cual coincide con lo mencionado en otros estudios (Carruthers et al., 2011). Aunque la deposición de nutrientes en el área estuarina o interna es alta, generalmente se utiliza como área de desove; por ello es posible que estos recursos ya hayan presentado eventos reproductivos [LT> 15 cm], lo cual les permite emigrar a zonas marinas y es lo que, quizá, haya posibilitado sus capturas (Sandoval et al., 2014). ...
