To reduce turtle interactions, regulations for the Hawaii-based longline swordfish fishery required vessels to switch from using a J-shaped hook with squid bait to a wider circle-shaped hook with fish bait. Analyses of observer data showed that, following the introduction of the regulations, significant and large reductions in sea turtle and shark capture rates occurred […]

The composite square-mesh panel: a modification to codends for reducing unwanted bycatch and increasing catches of prawns throughout the New South Wales oceanic prawn-trawl fishery | Consortium for Wildlife Bycatch Reduction
Composite-panel codend netting decreased catch of non-target species, including commercially important whiting, while increasing catches of prawns in the NSW, Australia oceanic prawn-trawl fishery. Increases in retained octopus and red mullet and discarded eastern blue spot flathead (probably due to their large size) were observed.
Deterring harbour porpoise from gillnets: observed reactions to passive reflectors and pingers | Consortium for Wildlife Bycatch Reduction
Three different device types were mounted on floatline to test their potential for reducing harbor porpoise bycatch. The devices were two passive reflectors (target strength ranging from -38 dB to -24 dB) and a 2.9 kHz pinger. Behavioral responses of 355 harbor porpoise groups were monitored. 92.4% of the groups avoided the pinger equipped floatline, […]

Overcoming Development, Regulatory and Funding Challenges for Rope-less Fishing in the U.S. and Canada The objectives of the workshop are to (1) discuss the need for and approaches to implementing rope-less fishing to reduce entanglements of large whales in trap/pot fisheries, (2) discuss and develop regulatory pathways to make rope-less fishing legal in the United States and Canada, and (3) discuss strategies […]
Field investigation of rare-earth metal as a deterrent to spiny dogfish in the Pacific halibut fishery | Consortium for Wildlife Bycatch Reduction
Rare earth metals (made of cerium mischmetal) were compared with control treatments of standard circle hooks and inert steel above circle hooks on longline fishing gear to determine if bycatch reduction of spiny dogfish could be achieved. Results indicated a slight reduction in dogfish bycatch and a greater reduction in catch of longnose skate on […]
New funding is available under the Global Fund for Marine Mammal Bycatch Solutions | Consortium for Wildlife Bycatch Reduction
Ocean Associates, Inc., in collaboration with the Consortium for Wildlife Bycatch Reduction and with funding from the National Marine Fisheries Service Office of International Affairs and Seafood Inspection, is pleased to announce the availability of grants to support capacity building for reducing marine mammal bycatch. The kinds of projects eligible for support can include: 1) Evaluation of […]
Effects of adding sounds to cod traps on the probability of collisions by humpback whales | Consortium for Wildlife Bycatch Reduction
Cod traps equipped with pingers resulted in a reduction in collisions with humpback whales (Megaptera novaeangliae) in Newfoundland, Canada. Traps with alarms caught more fish than traps without alarms.
Tests of artificial light for bycatch reduction in an ocean shrimp (Pandalus jordani) trawl: Strong but opposite effects at the footrope and near the bycatch reduction device | Consortium for Wildlife Bycatch Reduction
Artificial lights were attached to each the rigid-grate BRD and fishing lines in trawls for ocean shrimp (Pandalus jordani) off Oregon. Bycatch of eulachon (Thaleichthys pacificus), a threatened anadromous smelt species, was reduced on trawls with lights on the fishing lines as it was for slender sole (Lyopsetta exilis) and darkblotched rockfish (Sebastes crameri), without […]
Study on the catch, bycatch and discard of Chinese pelagic longline fisheries in the Atlantic Ocean | Consortium for Wildlife Bycatch Reduction
This study analyzed Chinese pelagic tuna longline observer data from 2010 to 2018 to determine catch composition of Atlantic targeting bigeye tuna (Thunnus obesus) and bluefin tuna (Thunnus thynnus), as well as the status and discard rate common bycatch species. A total of 55 species were observed as bycatch, and the most common was shark […]
Do pingers reduce interactions between bottlenose dolphins and nets around the Balearic Islands? | Consortium for Wildlife Bycatch Reduction
A large scale pinger trial was conducted and results showed a 49% decrease dolphin depredation rates when pingers were active. However the different pinger brands tried were not equally effective in reducing depredation. The AQUAmark 210 pingers had significant results, while Dukane Netmark 1000 and SaveWave Dolphinsaver High-impact did not have significant results. Profit per […]

North Atlantic Right Whale Consortium 2019 Annual Meeting | Consortium for Wildlife Bycatch Reduction
The North Atlantic Right Whale Consortium’s 2019 annual meeting is November 14-15, 2019. At this meeting, various stakeholders convene to discuss and share research, new techniques, management strategies, and other facets of right whale conservation. This is the only opportunity for this gathering and sharing of information and so is invaluable to the conservation of […]
Development and Evaluation of Reduced Breaking Strength Rope to Reduce Large Whale Entanglement Severity | Consortium for Wildlife Bycatch Reduction
1,700 lbf prototypes were developed and tested both in a lab and at sea to determine their fishing practicality. Use of these ropes have been documented as a strategy for reducing the incidence and severity of large whale entanglements in lobster pot buoy lines. Additionally, modeling work was carried out to assess the tensions placed […]
Preliminary report of side-setting experiments in a large sized longline vessel | Consortium for Wildlife Bycatch Reduction
Side-setting of longline fishing gear in the western North Pacific deterred seabirds– Black-footed albatross (Phoebastria nigripes) and Laysan albatross Phoebastria immutabilis)?from taking bait and improved the sinking rate of baited hooks.
