Abstract

Between April 1 and June 30, 1978, Departmental personnel sampled catches during 148 trips aboard commercial passenger fishing vessels operating in southern California. A total of 29,374 fishes representing 97 species were identified and measured. Otoliths for age determination studies were removed from 72 rockfish carcasses representing 11 species. In addition, nine long-range trips originating in San Diego and fishing in Mexican waters were sampled. A total of 1,190 fishes comprising 21 species was identified and measured at dockside from these vessels. The 10 most commonly taken species during the quarter accounted for 76.9% of the southern California catch. The most frequently sampled species were kelp bass, Paralabrax clathratus (21.1%); bocaccio, Sebastes paucispinis (15.5%); Pacific mackerel, Scomber japonicus (13.1%); white croaker, Genyonemus lineatus (6.0%); chilipepper, Sebastes goodei (4.8%); California barracuda, Sphyraena argentea (4.5%); kelp rockfish, Sebastes atrovirens (3.6%); barred sand bass, P. nebulifer (3.2%); halfmoon, Medialuna californiensis (2.6%); and blue rockfish, S. mystinus (2.6%). Data gathered from long-range vessels fishing off Baja California showed the top five species accounted for 94.0% of the fish sampled. The most frequently sampled species were yellowfin tuna, Thunnus albacares (34.4%); yellowtail, Seriola dorsalis (28.7%); wahoo, Acanthocybium solanderi (22.9%); snowy grouper, Epinephelus niveatus (5.9%); and leather bass, E. dermatolepis (2.0%).
