Albacore Trolling and Longline Exploration in Eastern North Pacific Waters during Mid-Winter 1981

摘要

Three chartered commercial fishing vessels using modified halibut longlining gear conducted an exploratory albacore longlining operation 700 to 900 N. miles west of San Diego during January-February 1981. Each vessel fished approximately 300 hooks per longline set in and about the thermocline at depths of 300 to 450 feet. Daily catches, standardized to 300 hooks/day, ranged from 0 to 37. The report recommends a more exploratory effort: to substantiate these findings, to expand the authors knowledge of albacore distribution in time and space, to understand further the relation of ocean features to albacore distribution, and to improve gear and fishing operations.
