Major Threats
This species is caught by long-lining, live-bait fishing, purse seining, and trolling. In the Eastern Pacific it is also a bycatch of swordfish fisheries. Albacore Tuna are caught by long-line gear in most of the North and South Pacific (but not often between about 10°N and 5°S), by trolling gear in the eastern and central North and South Pacific, and by pole-and-line gear in the western North Pacific. In the North Pacific about 60% of the fish are taken in pole-and-line and troll fisheries that catch smaller, younger Albacore Tuna, whereas about 90% of the albacore caught in the South Pacific are taken by long-line (IATTC 2008).
Catches of northern Atlantic Albacore Tuna are primarily made by pole-and-line (35%), trolling (28%), trawlers (17%) and longline (17%). The main fisheries are Spain, France, and Chinese Taipei. Surface fisheries concentrate mainly in the Bay of Biscay and the Azores and Canary Islands during summer and fall, taking young fish while longline vessels operate throughout the Atlantic year-round and target larger fish (ISSF 2010). For the south Atlantic stock, the main fisheries are longliners from Chinese Taipei (56%), pole-and-line from South Africa (18%) and from Namibia (13%). Surface fisheries operate mainly between October and May capturing juvenile and subadult fish (ISSF 2010).
