Longlining | Sustain Long line fishing is commonly associated with excessive land fishing for fish as well as arrabass. Environmental impacts of trawling and longline fishing, 40% of the global fisheries catch is bycatch, kill somewhere between 160,000 320,000 seabirds annually, Climate change and the collapse of fisheries, Top predators are essential to ecosystems: wolves revisited, Scariest part of climate change isnt what we know, but what we dont, Top predators are essential to the oceans. Disadvantages: Long line fishing can have serious environmental impacts due to the amount of gear used and the size of some fish that are caught. Trawlers, unlike other towed net bags, have a wide mouth and are closed with a special knot. Demersal longlines are also effective for catching bottom-dwelling fish such as cod and halibut. The risks to marine mammals from dredging are similar to the risks frombottom trawling. There is no definitive answer to this question as it depends on local laws and regulations.

Longline fishing is a technique where long fishing lines, up to 10 km long, and containing thousands of baited fishing hooks, are floated along the surface of the ocean to catch pelagic fish species such as tuna or marlin. Furthermore, baited hooks and nets can be extremely destructive in indiscriminately killing a wide range of marine life, including both commercial and subsistence species.
