Abstract

Commercial Passenger Fishing Vessel (CPFV) logs were analyzed to determine the degree of sea lion interactions in the CPFV fishery. From 1994 to 1996, sea lions depredated over 152,000 fish representing more than 40 different species. Although the depredation total seems high, it is still less than 10% of the fish caught by anglers. In southern California, sea lions primarily depredated California barracuda and mackerels, while in central and northern California, they depredated salmonids. Depredations in central and northern California were seasonal with most occurring during March and April. Southern California depredations occurred year-round with a majority from May through September. Sea lions directly affect CPFV fishing by consuming bait and chum and depredating hooked fish that are being reeled in. As sea lion populations continue to increase we would expect to see an increase in the number and degree of CPFV interactions and depredations. (23pp.)
