ICCAT Working Paper for Shark Stock Assessment Meeting 2008 Commercial Bycatch Rates of Shortfin Mako (Isurus oxyrinchus) from Longline Fisheries in the Canadian Atlantic
Shortfin makos (Isurus oxyrinchus) are a high-value bycatch of pelagic longline fisheries off the eastern coast of Canada. Annual catches in Canadian waters average 60-80 mt per year. Therefore, Canadian catches represent but a small part of that for the North Atlantic population as a whole. A stand...

Summary: | Shortfin makos (Isurus oxyrinchus) are a high-value bycatch of pelagic longline fisheries off the eastern coast of Canada. Annual catches in Canadian waters average 60-80 mt per year. Therefore, Canadian catches represent but a small part of that for the North Atlantic population as a whole. A standardized catch rate series was developed based on observed foreign tuna fleets fishing within Canadian waters and the Canadian swordfish fleet. There was no consistent trend in abundance since 1996 based on the standardized catch rate analysis. SCRS/2008/148 |
