Descending devices allow rockfishes that are not being retained, such as the Tiger Rockfish Sebastes nigrocinctus pictured here, to be released near depth of capture, minimizing complications related surface release floating, barotrauma injuries, and predation. Rockfishes (Sebastes spp.) a diverse group fish in order Scorpaeniformes distributed globally but concentrated North Pacific. Recogniza...

We examined genetic relationships among Sebastes rockfishes to evaluate the subgeneric relationships within Sebastes. We analyzed restriction site variation (12S and 16S rRNA and NADH dehydrogenase-3 and -4 genes) by using parsimony and distance analyses. Seventy-one Sebastes species representing 16 subgenera were included. Thirteen subgenera were represented by more than one species, and three...

A requisite for reliable food web models and ecosystem-based management in regions such as the California Current is the availability of diet information on key predators. In upwelling ecosystems, much of the lower trophic level energy may be transferred through a relatively small set of very abundant pelagic forage fish taxa, such as anchovies, sardines, smelts, and herring. In addition the pe...
