Bycatch - the capture of non-target species in fisheries - can amount to far greater quantities than the commercial stocks they are targeting. Around 20 million tons of bycatch are discarded annually by the world’s fisheries – a massive waste of marine life at a time when our oceans are under unprecedented fishing and other pressures. Bycatch occurs in many fisheries; EJF is currently focusing upon two fishing methods that pose a significant threat to marine biodiversity and local communities that are dependent on coastal resources:
Bottom Trawlers
Used to fish for shrimp (and other species) commercially. It is a "catch-all" technique that involves dragging large, fine-mesh nets along the seabed or through deepwaters. Shrimp trawlers, particularly those in the tropics, can catch over 400 marine species in their nets. Tropical shrimp fisheries typically take 10 kilos of bycatch for every 1 kilo of shrimp. Currently, tens of millions of tonnes of bycatch are taken by shrimp trawl fisheries worldwide each year, most of which is discarded. Shrimp fisheries alone are responsible for 27.3% of the world's discarded catch, despite producing less than 2% of global seafood.
