Use of pop-up satellite archival tags to demonstrate survival of blue marlin (Makaira nigricans) released from pelagic longline gear

摘要

Blue marlin (Makaira nigricans) support commeicial and recreational fisheries throughout the tropical and subtropical waters of the Atlantic Ocean. The species is taken in directed recreational and artisanal fisheries in several areas and constitutes an incidental catch of the widespread commeicial pelagic longline fishery. Although blue mailin comprise only a small fraction of the catch of the pelagic longline fishery that targets tunas and swordfish, this fishery accounts for the majority of fishing mortality on Atlantic blue marlin (ICCAT, 1997; 2001).
