Typical Longline Setup For Tuna

The commercial fishing technique that uses hundreds of baited hooks hanging from a single line. Longlines are set to hang near the surface to catch fish such as tuna and swordfish or along the sea floor for groundfish such as halibut.

Compared to other fishing techniques such as bottom trawling, longline fishing results in relatively little destructive impact on bottom habitats. It generally has good species selectivity and low fuel consumption.
