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

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