Longline fishing
Definition:
Longline fishing is a commercial fishing technique that involves setting out a long mainline with multiple baited hooks attached at intervals along its length. This method is commonly used to target deep-sea fish species such as tuna and swordfish.
The Practice of Longline Fishing
Longline fishing is a commercial fishing technique that uses a long line with baited hooks attached at intervals. This method is commonly used to catch fish such as tuna, swordfish, and halibut in deep waters.
How Does Longline Fishing Work?
Ships equipped for longline fishing deploy a main fishing line that can stretch for miles, with secondary lines branching off the main line at regular intervals. Each secondary line has multiple hooks baited with squid, fish, or artificial lures to attract the target species. The lines are left in the water for a period of time before being hauled back on board.
The Environmental Impact of Longline Fishing
While longline fishing can be an effective way to catch large quantities of fish, it can also have detrimental effects on marine ecosystems. Bycatch, which refers to the unintentional capture of non-target species such as sea turtles, seabirds, and sharks, is a major concern associated with longline fishing.
Conclusion: Longline fishing remains a controversial practice in the fishing industry due to its impact on non-target species and the marine environment. Efforts are being made to mitigate these negative effects through the development of new technologies and regulations to promote sustainable fishing practices.
