Which is the most common cause of bycatch in fishing?
Causes. Longlines, trawling and the use of gillnets are the fishing methods that most commonly result in bycatch. Longlining is a commercial fishing method commonly targeting swordfish, tuna and halibut, where hundreds or thousands of baited hooks hang at intervals along a single fishing line.
How are gill nets used to catch bycatch?
Although gill nets are intended to catch certain species of fish, this fishing practice can result in a large quantity of bycatch. Thousands of hooks all fish at once when a long-liner rolls out the gear. The central fishing line can be fifty miles long and strung with many smaller lines holding baited hooks.
Which is the most effective way to prevent bycatch?
The single easiest and most effective way to prevent bycatch, is for more people to stop eating fish. If demand for fish reduces, it will be less economically viable for the fishing industry to continue with fishing practices that cause bycatch. Furthermore, do not trust sustainability labelling.
How is bycatch harmful to the marine environment?
Not only does it cause avoidable deaths and injuries, but the fishing methods can be harmful to the marine environments where they are employed. WWF aims to reduce bycatch by working with fisheries and helping develop and promote new technologies and gear for more efficient operations.
