Soffker, M., Trathan, P., Clark, J., Collins, M.A., Belchier, M. and Scott, R. [email protected] Depredation by antarctic fur seals (Arctocephalus gazella), sperm whales (Physeter macrocephalus) and orcas (Orcinus orca) were studied in a Patagonian toothfish (Dissostichus eleginoides) fishery operating around South Georgia. While sperm whales come in contact with about one third of longlines (averaged […]

Release efficiency and selectivity of four different square mesh panel configurations in the Basque mixed bottom trawl fishery | Consortium for Wildlife Bycatch Reduction
Submitted by lweiss on February 13, 2020 – 12:32 hake (Merluccius merluccius), megrim (Lepidorhombus, spp.), and anglerfish (Lophius spp.) Placing the square mesh panel lower in. the trawl net panel increased escape of undersized hake Increasing panel size increased escapes of blue whiting Excluder devices Visual deterrents
The efficacy of illumination to reduce bycatch of eulachon and groundfishes before trawl capture in the eastern North Pacific ocean shrimp fishery | Consortium for Wildlife Bycatch Reduction
Lomeli, M. J., Groth, S. D., Blume, M. T., Herrmann, B., and W.W. Wakefield Canadian Journal of Fisheries and Aquatic Sciences Mark J.M. Lomeli 1-541-867-0544 [email protected] This study examined the extent that eulachon (Thaleichthys pacificus) and groundfishes escape trawls in response to artificial illumination. Using a double-rigged trawler, catch efficiencies were compared for ocean shrimp, […]
Field Study 340 | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on December 10, 2010 – 16:53 Catch rates of yellowfin tuna caught in the fall were higher on circle hooks. Yellowfin tuna were caught four times as often in the mouth when circle hooks were used in the fall. Pelagic stingrays had higher catch rates on J-style hooks and survival rates of […]
Experimental fishing with an “umbrella-and-stones” system to reduce interactions of sperm whales (Physeter macrocephalus) and seabirds with bottom-set longlines for Patagonian toothfish (Dissostichus eleginoides) in the Southwest Atlantic | Consortium for Wildlife Bycatch Reduction
Goetz, S., Laporta, M., Portela, J.M., Santos, M.B., Pierce, G.J. ICES Journal of Marine Science Sabine Goetz: [email protected] The Patagonian toothfish longline fishery in the Southwest Atlantic suffers from depredation of fish by sperm whales and high bycatch rates of seabirds. This study assessed depredation and seabird bycatch using a modified longline with an “umbrella” […]
Field Study 804 | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on June 13, 2013 – 09:25 Performance of pulse trawling compared to conventional beam trawling Significantly fewer plaice and sole Significantly fewer invertebrates; no difference in undersized plaice; significantly fewer undersized sole Modified ground gear (mobile)

Shorter trawls improve size selection of northern shrimp | Consortium for Wildlife Bycatch Reduction
Submitted by lweiss on February 13, 2020 – 12:45 Shorter trawls improve size selection of northern shrimp Northern shrimp (Pandalus borealis) The trawls fished shrimp above 19 mm carapace length equally, while catch rates of shrimp below 15.5–16 mm carapace length in the shorter trawl were more than halved. Bycatch of Norway pout was slightly […]
ant | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on May 9, 2010 – 14:41 Low-profile gillnet testing in the deep water region of Pamlico Sound, NC. Reduced catches of flounders Reduced incidental capture of sea turtles and bycatch species Sub-surface sets (gillnets)
Effects of circle hooks on pelagic catches in the Hawaii-based tuna longline fishery | Consortium for Wildlife Bycatch Reduction
Curran, D. and Bigelow, K. Tests were conducted aboard deep-set Hawaii tuna longline vessels to determine differences in catches, fish size selectivity and survival on 18/0 circle hooks vs. Japanese style tuna hooks size 3.6 sun and vs. 9/0 “J” hooks. There were no significant differences in catch, catch rate or mean length between hook […]

Experiment to Evaluate Gear Modification on Rates of Sea Turtle Bycatch in the Swordfish Longline Fishery in the Azores Phase 2 | Consortium for Wildlife Bycatch Reduction
Bolton, A. and K. Bjorndal Final Project Report submitted to the U.S. National Marine Fisheries Service. Archie Carr Center for Sea Turtle Research, University of Florida, Gainesville Circle hooks (non-offset 16/0 and 18/0) did not significantly reduce the number of loggerhead sea turtles (Caretta caretta) caught in the Azores longline swordfish and blue shark fishery […]

Reducing seabird bycatch in longline fisheries by means of bird-scaring lines and underwater setting | Consortium for Wildlife Bycatch Reduction
In Edward F. Melvin and Julia K. Parrish, eds. Seabid Bycatch: Trends, Roadblocks and Solutions. Bird-scaring lines and an underwater setting funnel reduced seabird bycatch in longlines off the coast of Norway. Catch of haddock (Melanogrammus aeglefinus), torsk (Brosme brosme), and ling (Molva molva) increased with use of the underwater setting funnel. http://nsgl.gso.uri.edu/aku/akuw99002.pdf
