Hook-and-Line Fishing Study at Cordell Bank, California, 1986-1991

摘要

Hook-and-line landings at the marine bank, Cordell Bank, California, wereidentified and quantified from 1986-1991. A total of 45 charter cruises were conducted in which an average 11.5 anglers expended 3.9 hours fishing. The mean vessel catch per trip was 162 fish landed, resulting in a total catch of 7,439 fish during the entire study. No annual pattern to the catch-per-unit effort was apparent, while interannual differences were found. Twenty-eight different fish species were identified during the study; a mean of 15.3 species per trip was observed. Rockfishes (genus Sebastes) dominated the catches, comprising over 80% of all landings. Yellowtail rockfish (S. flavidus), the target species of the research effort, made up 47.9% of the total catch. In comparison with coastwide landings, Cordell Bank was found to be a consistently productive fish habitat that supported a diverse fish community.
