How does sustainable fishing work?

Sustainable fishing means fishing in a responsible way that prevents overfishing, minimises bycatch and maintains marine biodiversity.

What are some disadvantages of longline fishing?

Leaders, called gangions or snoods, with baited hooks are attached to the mainline. A longline set can have up to a thousand baited hooks and once deployed can soak anywhere from hours to days.

What is bycatch and why is it harmful to the environment?

For NOAA Fisheries, bycatch refers to“discarded catch of marine species and unobserved mortality due to a direct encounter with fishing vessels and gear.” These unintentionally caught animals often suffer injuries or die. NOAA Fisheries is committed to continuing to reduce and minimize bycatch now and into the future.

What is demersal longlining?

Demersal long line is used to target the bottom feeding fish in particular cod, haddock, ling and some flatfish. It can be very size selective by variation in hook size and the species can be regulated by the skippers experience in where he shoots his gear, what depth of water and what bait is used.

What type of fishing has the most bycatch?
