Description
Longline tuna fishing is a commercial fishing technique that involves using a long line with baited hooks to catch tuna. A longline fishing vessel trails a long main line behind it, with baited hooks attached at regular intervals. The line may also have branch lines attached. Longlines can be used to target a variety of tuna species, including albacore, bigeye, yellowfin, and bluefin. Longline vessels are typically 15 to 60 meters long and have a fish hold capacity of 20 to 500 metric tons.
