Fratto, Z.W., Barko, V.A., Pitts, P.R., Sheriff, S.L., Briggler, J.T., Sullivan, K.P., McKeage, B.L. and Johnson, T.R. The Journal of Wildlife Management Three modified hoop-net designs were tested in the Gasconade and Osage Rivers of Missouri to determine their ability to reduce turtle bycatch without reducing the capture of targeted catfish. The three designs included […]

Trial setting of deep longline techniques to reduce bycatch and increase targeting of deep-swimming tunas | Consortium for Wildlife Bycatch Reduction
Beverly, S., Robinson, E., Itano, D. Pelagic longlines were weighted with lead weights, enabling them to fish deeper in the water column than traditional pelagic longlines. Weighted longlines caught 31 target species with a slightly higher catch per unit effort (CPUE) of 1.3 fish/100 hooks (49 kg/100 hooks) compared to traditional gear (38 target species […]
Mitigating bycatch of freshwater turtles in passively fished fyke nets through the use of exclusion and escape modifications | Consortium for Wildlife Bycatch Reduction
Larocque, S.M., Cooke, S.J. and Blouin-Demers, G. Two types of excluder devices, one with exclusion bars and one with exclusion rings, were fitted at the entrance to fyke nets to determine their efficiency in reducing turtle bycatch. In addition, the efficacy of an escape chimney, compared to a net with a large hole, was tested. […]
Spatiotemporal patterns of overlap between short-finned pilot whales and the U.S. pelagic longline fishery in the Mid-Atlantic Bight: an assessment to inform the management of fisheries bycatch | Consortium for Wildlife Bycatch Reduction
Stepanuk, J.E.F., Read, A.J., Baird, R.W., Webster, D.L. and Thorne, L.H. School of Marine and Atmospheric Sciences, Stony Brook University, Stony Brook, NY, 11794-5000, USA This research examined the spatial and temporal characteristics of pilot whale habitat use and longline fishing effort. The information was used to assess the potential for a spatial management approach […]
Field Study 321 | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on August 21, 2010 – 16:11 Reduced the proportion of soft and damaged prawns by 63.2% and reduced catches of tiger prawns by 6.3% Downward facing TEDs reduced sea turtle catches by 100%
Field Study | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on July 13, 2010 – 13:30 Increased the total catch rate by 25.7%, the catch rate of sublegal crabs by 14.5% and of legal crabs by 32.9% No diamondback terrapins were caught during the study
Field Study 361 | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on January 21, 2011 – 17:25 There were no differences in the mean length at capture, but signficantly more swordfish were caught on the monofilament gangions. Signficant differences in catch rates for blue sharks and pelagic stingrays between the two gangions, with more animals being caught on the monofilament gangions. No significant […]
Interactions between the Indian River Lagoon blue crab fishery and the bottlenose dolphin, Tursiops truncatus | Consortium for Wildlife Bycatch Reduction
Noke, W.D., and D.K. Odell Trap guards, made of bungee cords, reduced interactions between bottlenose dolphin (Tursiops truncatus) and the Indian River Lagoon blue crab (Callinectes sapidus) pot fishery.
Acoustic harassment devices reduce seal interaction in the Baltic salmon-trap, net fishery | Consortium for Wildlife Bycatch Reduction
Submitted by AMackay on February 3, 2009 – 11:47 Increased target catch and reduced seal damage to the catch Reduced depredation of salmon traps by grey seals (Halichoerus grypus) Acoustic deterrent devices
Could green artificial light reduce bycatch during Barents Sea deep-water shrimp trawling? | Consortium for Wildlife Bycatch Reduction
Larsen, R.B., Herrmann, B., Sistiaga, M., Brcic, J., Brinkhof, J. and Tatone, I. The Arctic University of Norway, UiT, Breivika, N-9037 Tromsø, Norway Light-emitting diodes (LEDs) were mounted on the lower part of a Nordmore grid to determine if they would encourage fish to move up towards the escape outlet prior to contacting the grid. […]
A comparison of catches of swordfish, Xiphias gladius, and other pelagic species from Canadian longline gear configured with alternating monofilament and multifilament nylon gangions | Consortium for Wildlife Bycatch Reduction
Heath H. Stone Biological Station Fisheries and Oceans Canada 531 Brandy Cove Road St. Andrews, New Brunswick, Canada [email protected] Tests were conducted aboard Canadian longline vessels targeting swordfish to determine if there were differences in the catch rates and size composition of swordfish and bycatch species caught by monofilament and multifilament nylon gangions. No significant […]
Effects of eliminating shallow hooks from tuna longline sets on target and non-target species in the Hawaii-based pelagic tuna fishery | Consortium for Wildlife Bycatch Reduction
Submitted by ezollett on January 7, 2009 – 11:40 Decreased catch of wahoo, dolphinfish, blue and striped marlin, and shortbill species, increased catch of sickle pomfret and opah, and did not affect catch of sharks and pelagic sting rays No differences in catches between experimental and control sets
Field Study 363 | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on January 21, 2011 – 17:29 There were no differences in the mean length at capture, but signficantly more swordfish were caught on the monofilament gangions. No signficant difference in catch rates between gangions for loggerhead sea turtles. Caretta caretta (Loggerhead turtle) Alternative leader design
