Longline
A main fishing line, sometimes tens of kilometres long, with thousands of baited hooks on short side lines.
Also: longlining
A longline is a main line set from a boat and left to fish, with branch lines and baited hooks hanging from it. Pelagic longlines drift near the surface for tuna, swordfish and sharks; bottom longlines target cod, halibut, toothfish and groupers. One line may carry thousands of hooks. Longlining can catch high-quality fish, but it also hooks sharks, turtles and seabirds such as albatrosses. Weighted lines, setting at night, bird-scaring streamers and circle hooks reduce this bycatch.
