longliners
Hook-and-line vessels
Longliners are commercial fishing vessels that use longlines—main lines extending for miles with thousands of baited hooks attached at intervals.
The method targets tuna, swordfish, halibut, and other deep-water species.
Longliners are controversial for bycatch problems, inadvertently hooking sea turtles, sharks, and seabirds: Environmental groups have pushed for stricter regulations on longliners.
