Abstract

From l July through 30 September, 1976, Department personnel made 138 sampling trips aboard southern California partyboats. A total of 15,827 fishes from 75 species was identified and measured. Otoliths were removed from 290 rockfish carcasses representing 23 species for use in age determination studies. The 10 most common species sampled during this quarter were kelp bass, Paralabrax clathratus (22.9%); barred sand bass, P. nebulifer (13.7%); olive rockfish, Sebastes serranoides (12.0%); bocaccio, S. paucispinis (1l.6%); Pacific bonito, Sarda chiliensis (6.6%); California barracuda, Sphyraena argentea (5.9%); white croaker, Genyonemus lineatus (4.5%); blue rockfish, S. mystinus (2.9%); brown rockfish, S. auriculatus (2.8%); and ocean whitefish, Caulolatilus princeps (2.8%). Preliminary results from California partyboat logs indicate landings of Pacific bonito, California barracuda, kelp bass, and barred sand bass were significantly larger than those of 1975, while the low catch rates of yellowtail and white seabass remained approximately equal to those of the previous season.
