Composición taxonómica y aspectos zoogeográficos de peces de profundidad (90-540m) del Golfo de California, México.

Abstract

Taxonomic composition and zoogeographical aspects of deep sea fishes (90-540m) from the Gulf of California, Mexico. The Gulf of California has a high variety of ecosystems that allow different services and the fishery resources play a prominent role in its ecology, evolution and economics. Fish coastal species have been previously reported for most coastal areas, especially those species that are subject to fishing, however, little is known on the species from deep sea zones, due to sampling difficulties. We studied the deep sea fishes collected with trawl nets during three research surveys in the Gulf of California, Mexico in 2004-2005. We provide a systematic checklist and some notes on biogeographical aspects. For this, 74 fishing hauls were done, and a total of 9 898 fishes were captured, belonging to two classes, 15 orders, 35 families, 53 genera and 70 species. The best represented families in number of species were: Paralichthyidae (eight), Serranidae (six), and Scorpaenidae and Triglidae with five species each one. The typical families from deep waters were: Ophidiidae, Moridae, Lophiidae, Scorpaenidae, Triglidae, Paralichthydae, Pleuronectidae and Cynoglossidae. Size range varied from 13cm for the Splinose searobin (Bellator xenisma) to 234cm in the Pacific Cutlassfish (Trichiurus nitens). The biogeographical affinity showed that species with affinity to the East Tropical Pacific (ETP) dominated, followed by species from San Diego-Panamic, San Diego-Panamic-Peruvian-Chilean and Oregonian-Cortes provinces, respectively. A biogeographic overlap was found in the fauna, which reflects the Gulf of California's geographical position, with distribution limits of species from temperate, tropical and warm-temperature transition affinities, divisions that characterize the Gulf of California. Taxonomic status of fish with a focus on composition, location, characterization and zoogeography are fundamental to any subject of biodiversity and fisheries management actions. Rev. Biol.

Bathymetric range extension of the Peruvian flounder Etropus peruvianus Hildebrand, 1946 in the Gulf of California, Mexico

“…Sex distribution showed greater proportion of females in a depth range from 170 to 230 m and of males from 230 to 270 m. The majority of the females were from maturity stage III to V (82%); 98% of the males were from stages I to III. (López-Martínez et al, 2012;Rábago-Quiroz et al, 2015). The greater abundances could be related to migratory habits from deeper to shallower waters for reproductive purposes (Rábago-Quiroz et al, 2015), which explains the greater proportion of mature females and at greater depths than males.…”

“…The Peruvian flounder Etropus peruvianus (Paralichthyidae) occurs in the East Pacific, from Baja California to Perú, including the Gulf of California ( Van der Heiden, 2010;López-Martínez et al, 2012;Del MoralFlores et al, 2013), where it is identified as a component of the Sinuscalifornian, Mexican, and Panamic provinces. The Peruvian flounder ranges at depths of 46 to 125 m in benthic habitats close to sandy and muddy bottoms, including rubble, its maximum size is 100 mm in total length (Hensley, 1995).…”

“…The Peruvian flounder ranges at depths of 46 to 125 m in benthic habitats close to sandy and muddy bottoms, including rubble, its maximum size is 100 mm in total length (Hensley, 1995). This species is listed as Least Concern (LC) in the International Union for the Conservation of Nature ( Van der Heiden, 2010), it has been reported in the list of shrimp bycatch fauna in the Gulf of California (Rábago-Quiroz et al, 2008;Acevedo-Cervantes et al, 2009;López-Martínez et al, 2010;López-Martínez et al, 2012;Rábago-Quiroz et al, 2015).…”
