Pelagic shrimps collected during the TALUD I-VII cruises aboard the R/V “El Puma” in the SE Gulf of California, Mexico

Abstract

A total of 15 species of pelagic shrimps were collected during the TALUD cruises I-VII (R/V “El Puma”, UNAM) in 1990 and in 2000-2001 in the southeastern Gulf of California, including seven species of Dendrobranchiata (Hymenopenaeus doris, Sergia phorca, S. filicta, Parasergestes halia, Eusergestes similis, Gennadas incertus, and G. sordidus) and eight species of Caridea (Pasiphaea americana, P. emarginata, Hymenodora glacialis, Acanthephyra brevicarinata, A. cf. brevirostris, Plesionika trispinus and Maryprocessa pippinae). Most frequently collected species were G. sordidus (56% of samples), S. phorca (40%), P. emarginata (32%), P. americana and H. doris (both 28%). Most abundant species in the samples were G. sordidus, S. phorca, S. similis and P. trispinus. Sampling was performed between the surface to more than 2000 m. This explains the presence of P. emarginata, a deep-water species rarely reported from the area and not found in much shallower samples taken by the R/V “El Puma” in 1981-1985.
