Experiments in the Western Atlantic Northeast Distant Waters to Evaluate Sea Turtle Mitigation Measures in the Pelagic Longline Fishery. Report on Experiments Conducted in 2001 | Consortium for Wildlife Bycatch Reduction
Watson, J., D. Foster, S. Epperly, and A. Shah US National Marine Fisheries Service Blue-dyed bait does not significantly reduce loggerhead (Caretta caretta) and leatherback (Dermocheles coriacea)sea turtle captures in the western Atlantic longline fishery. http://www.sefsc.noaa.gov/PDFdocs/UPR_Watson1_2002.pdf

Field Study 345 | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on December 27, 2010 – 15:04 In experiment 2, where a trawler was placed in front of the mouth of the net, the selection range of school prawns was incrementally smaller from the 1-m square-mesh codend to the 3-m square mesh codend compared to the diamond mesh codend and school praw
Extension trial of an acoustic deterrent system to minimize dolphin and porpoise bycatch in gill and tangle net fisheries | Consortium for Wildlife Bycatch Reduction
Kingston, A. and Northridge, S. Fisheries observers and skippers tested the effectiveness of the Dolphin Dissuasive Device (DDD) as a bycatch mitigation tool for porpoises and dolphins. This study was conducted aboard fishing vessels in the Cornish over-12m static net sector fishery in the waters of Southwest England. DDD’s were placed at the end nets. […]
Effects of chemicals from longline baits on the biting behaviour of loggerhead sea turtles | Consortium for Wildlife Bycatch Reduction
Piovano, S., A. Farcomeni, and C. Giacoma African Journal of Marine Science [email protected] The biting behaviour of the loggerhead sea turtle, Caretta caretta, a high bycatch species by longling fishing gear, was studied on 30 wild specimens held temporarily at rescue centers. Chemicals from squid baits elicited significantly more biting behaviour than those from mackerel […]

Glossary of Bycatch Reduction Techniques | Consortium for Wildlife Bycatch Reduction
Underwater sound-emitting devices (maximum level of intensity equivalent to approximately 175 dB re 1 µPa @ 1m) attached to fishing gear, principally gillnets. ADD’s such as acoustic pingers are now mandated for use in some fisheries in the U.S. Northwest Atlantic, California driftnet, and in Europe. The sound of these devices is believed to alert […]
International Marine Mammal – Longline Bycatch Mitigation Workshop | Consortium for Wildlife Bycatch Reduction
Tuesday, October 22, 2013 to Friday, October 25, 2013 Mortality from longline bycatch threatens marine mammal species and populations such as the false killer whale (Pseudorca crassidens) in the insular Hawaiian Islands, and Risso’s dolphin (Grampus griseus) and pilot whales (Globicephala spp.) in the Northwest Atlantic. Fishermen also lose valuable target catch due to marine […]

Reducing longline bycatch: the larger the hook, the fewer the stingrays | Consortium for Wildlife Bycatch Reduction
Piovano, S., S. Clo, and C. Giacoma Pelagic stingrays (Pteroplatytrygon violacea) are a common bycatch species in the Mediterranean pelagic longline swordfish fishery. Experimental trials took place in the central Mediterranean Sea from 2005 to 2007 to investigate the importance of bait size, presence and type of light attractors, and hook size and shape on […]
