Abstract

Partyboats were sampled during the months of May through October 1972-1974 to collect length frequency data for California barracuda, Sphyraena argentea; Pacific bonito, Sarda chiliensis; white seabass, Cynoscion nobilis; and yellowtail, Seriola dorsalis. Age-length keys were applied to the data to estimate the age composition of each species and an analysis of variance was performed on the results. Ratio estimates were also computed to examine the variation due to month and port complex. The project provided background data for current stock assessments of these species.
