Abstract

From October through December 1976, Department personnel made 160 sampling trips aboard southern California partyboats. A total of 25,574 fishes from 80 species was identified and measured. Also, otoliths were removed from 722 rockfish carcasses representing 28 species for use in age determination studies. The 10 most common species sampled were bocaccio, Sebastes paucispinis (33.3%); chilipepper, S. goodei (16.0%); olive rockfish, S. serranoides (6.1%); kelp bass, Paralabrax clathratus (4.6%); blue rockfish, S. mystinus (4.5%); Pacific mackerel, Scomber japonicus (4.4%); widow rockfish, S. entomelas (2.4%); vermilion rockfish, S. miniatus (2.0%); ocean whitefish, Caulolatilus princeps (1.9%); and greenstriped rockfish, S. elongatus (1.9%). The sampled quarter represented a transitional period in the partyboat fishery during which effort shifted from "surface" fishing to deep water "rockcod" fishing. (23pp.)
