Hyperiid amphipods from the Gulf of Ulloa and offshore region, Baja California: Intermittent use of the coastal shelf

Hyperiid amphipod species from the Gulf of Ulloa, Baja California, and the adjacent region (from shelf break to 200 km offshore) were analyzed in order to evaluate diversity and abundances in this productive area that supports small-scale commercial fisheries such as barred sand bass (Paralabrax nebulifer), California spiny lobster (Panulirus interruptus), abalones, clams, and others. Strong coastal upwelling events were observed during summer seasons of the period 2002- 2008 between Punta Eugenia and Punta Abreojos. The upwelling plumes at Punta Abreojos are projected southward in slope waters bordering the coastal shelf of the Gulf of Ulloa, contributing to the separation of coastal and oceanic regions, and explain differences in amphipod diversity and abundances. In the offshore region, the most abundant species were Vibilia armata, Lestrigonus schizogeneios, Primno brevidens, and Eupronoe minuta, similar to previous findings in northern regions of Baja California and southern California. However, their abundances were lower (between 10 and 30 individuals/1000 m3), only reaching 20-50% of abundance levels reported off northern Baja California. In the coastal shelf of the Gulf of Ulloa, amphipods were virtually absent during ...Continue Reading
