Long line fishing is a method by which a main line is set out with multiple baited "branches" or "snoods". This commercial fishing technique is prone to cause the 'incidental' deaths of sea birds, turtles, and sharks.
Releasing one line near the surface or on the sea bed with hundreds of baited hooks is used worldwide to target Swordfish, Tuna, Halibut, and Sablefish.
Fisheries in some areas are using thousands of hand baited hooks to draw in maximum catches. In the North-Pacific some fishing fleets are known to use 2,500 hooks on a single line extending many miles!!
As multiple sea animals are attracted to the bait on long lines, they become entangled in the line to often drown. Long line fishing is responsible for multiple ocean species becoming endangered due to the excessive by-catch ratio of this fishing method.
