Fish larvae in the biosphere reserve of the upper Gulf of California (June 2008, June 2010)

Sylvia Patricia Adelheid Jiménez Rosenberg, Laura Sánchez Velasco y F.E. Ordóñez-Guillén

The Upper Gulf of California is an important Biosphere Reserve which, despite of its extreme environmental conditions, houses high fish species richness. Two intensive prospections of fish larvae were made during June 2008 and June 2010 as part of multidisciplinary project PANGAS-III. From 54 and 75 zooplankton sampling stations, respectively, a total of 47,939 fish larvae were collected. Fish larvae of 141 taxa were identified, 42 families were represented being Engraulidae (3 taxa) and Clupeidae (6 taxa) the most abundant (46% and 29% of total larval abundance), while families Serranidae (16 taxa), Scianidae (13 taxa) and Gobiidae (11 taxa) were the most diverse. Larvae of Opisthonema libertate (Clupeidae), Anchoa spp (Engraulidae), Serranus sp 1 (Serranidae), Sciaenidae type 1, Gobulus crescentalis (Gobiidae) and Etropus crossotus (Paralichtyidae) were dominant in both years. The number of taxa registered confirms the high fish species richness, compared to adjacent marine regions were fish larvae of about 50 taxa have been registered during summer.
