Southern California marine sport fishing from privately owned boats: catch and effort for July-September 1982
1983
Ono, David S.
The catch landed and effort expended by private-boat sportfishermen were studied in southern California between Julyand September 1982, to determine the impact of that segmentof the sport fishery on local marine resources. Fishermenreturning from fishing trips were interviewed at launch ramps, hoists, and boat-rental facilities. This report contains quantitative data and statistical estimates of total effort, total catch, catch of preferred species, and length frequencies for those species whose catches are regulated by minimum size limits.An estimated 287,000 organisms were landed by 132,200 anglers and 5,800 divers. The two major components of the catch were Pacific mackerel, Scomber japonicus (98 000 landed), and white croaker, Genyonemus lineatus (46 000 landed). Together these two species made up over half of the estimated 270 000 fish-angler catch. Basses, Paralabrax spp., and rockfishes, Sebastes spp., made up 15% and 12% respectively, of the angler catch. Abalone, Haliotis spp., and rock scallop, Hinnites multirugosus, combined to form over half the diver catch of 16 700 organisms.Angler compliance with size limits varied greatly depending on the species in question. Compliance was particularly poor for white seabass, Atractoscion nobilis; California halibut,Paralichthys californicus; California barracuda, Sphyraneaargentea; and Pacific bonito, Sarda chiliensis. The compliance rate for the above group ranged from a high of 70% for California halibut down to 4% for Pacific bonito. The diver size-limit compliance rate for abalone, Haliotis spp., was 97%, almost 5% higher than last year's July-September compliance rate. (35pp.)
