Description:
The catch landed and effort expended by private-boatsport fishermen were studied in southern Californiabetween April and June 1981, in order to determine theimpact of one segment of the sport fishery on local marineresources. Fishermen returning from fishing trips wereinterviewed at launch ramps, hoists, and boat-rentalfacilities. This report contains quantitative data andstatistical estimates of total effort, total catch, catchof preferred species, and length frequencies for thosespecies whose catches are regulated by minimum size limits.An estimated 310,000 organisms were landed by 106,000anglers and 4,000 divers (more than twice the catch andeffort estimated for the previous 3-month period). Themajor components of the catch were Pacific mackerel, Scomberjaponicus, 63,000 landed; bass, Paralabrax spp., 61,000landed; white croaker, Genyonemus lineatus, 52,000 landed,and Pacific bonito, Sarda chiliensis, 35,000 landed. Thesespecies contributed 70% of the total catch.Anglers' compliance with size limit regulations was variable. Approximately 89% of all measured bass were legal size. The proportion of legal size California halibut, Paralichthys californicus, rose from 60% last quarter to 79% this quarter. However, the percent of legal size California barracuda, Sphyraena argentea, was very low, 58%. Divers' compliance with minimum size limits dropped slightly: abalone, Haliotis spp., averaged 89% legal. (Document has 31 pages)
