Opaque mesh netting placed strategically on gillnets decreased bycatch of rhinoceros auklet (Cerorhinca monocerata) and common mure (Uria aalge) seabirds but also decreased catch of target salmon species in the Puget Sound, USA.

Bottom trawls and bycatch UK proposes to extend trawling ban Support for reducing finning and bycatch of sharks Why we do what we do Who better than the incomparable David Attenborough to explain why our Conssortium exists?

Dyed bait, streamer lines, and weighted bait used in Hawaii longlines each resulted in reduced contact between seabirds (Black-footed (Phobastria nigripes) and Laysan (Phoebastria immutabilis) albatrosses) and bait.

How Serious is Bycatch?   Some would argue that bycatch is an acceptable consequence of supplying the world with wild-caught seafood. However, too often the scale of mortality is so high that it threatens the very survival of species and their environments. Every year, at least 7.3 million tons of marine life are caught incidentally. In […]

Modified trap openings were developed to reduce juvenile rockfish bycatch in British Columbia spot prawn traps. Smaller trap openings had no impact on rockfish or other non-target species bycatch. A novel bent tunnel opening resulted in no rockfish bycatch and the exclusion of other fish species. However, all trap modifications resulted in reductions in prawn […]

The small population of North Atlantic right whales is in danger of extinction. These whales were hunted nearly to extinction by commercial whalers by the end of the 1700s, but today are at risk from entanglement in fishing gear and boat strikes.    At least 82% of the North Atlantic right whale population has been entangled […]

Low profile gillnets with a panel height of six feet and no tie downs or additional floats had significantly fewer interactions with sea turtles and caught significantly less bycatch than standard gillnets. Catches of the target species (flounder) were also reduced in the low profile gillnets.

An acoustic device designed to deter false killer whales from approaching longlines by reducing the whales’ echolocation performance capabilities was tested on a trained false killer whale. The device, Longline Saver, produced a series of complex, broadband signals (1-250 kHz) at high intensity levels (up to 182 dB). The whale was asked to detect a […]

Codends modified with rectangular mesh panels (one oriented length-wise in the cod end and one oriented width-wise, each measuring 7 x 11 bars) reduced the weight of discarded bycatch by 46% and 38% respectively but did not significantly reduce the catch of targeted prawns. A haulback delay of 10-15 seconds allowed juvenile red spot to escape […]

Acoustic pingers placed in the rear of a pair trawl net in the United Kingdom bass pair trawl fishery did not reduce bycatch of common dolphins (Delphinus delphis). Multi-monofilament net, placed in the North Sea and West of Scotland gillnet fisheries, had no significant impact on harbour porpoise (Phocoena phocoena) bycatch when compared to traditional […]

This study investigated the impact of rope polymer type, breaking strength and diameter in relation to the injury severity of entangled baleen whales, primarily North Atlantic Right whales (Eubalaena glacialis). Fishing gear removed from live and dead entangled whales from the US East Coast and Canadian Maritimes region between 1994 and 2010 were included in […]

18/0 circle hooks when compared with J hooks significantly reduce loggerhead (Caretta caretta) and leatherback (Dermocheles coriacea) sea turtle bycatch in Atlantic longline fisheries for pelagic swordfish. Circle hooks also reduced the rate of hook ingestion by loggerhead sea turtles. The combination of circle hooks and mackerel bait was the most effective in reducing sea […]

Metal oxide nets containing barium sulphate (that increased their acoustic reflectivity and probably also their stiffness) reduced the bycatch of harbor porpoise (Phocoena phocoena) in an eastern Canada demersal gillnet fishery. No difference in catch of commercial fish species, including cod, pollock, haddock, and spiny dogfish, was observed between the nylon and barium sulphate nets. […]
