Submitted by morgaac on August 24, 2015 – 15:47 Equatorial Atlantic Ocean Bigeye and yellowfin tuna had higher survival rates when circle hooks were used Sailfish, pelagic stingrays, and leatherback sea turtles, had higher catch rates on J-style hooks Bony Fishes Skates/Rays Demochelys coriacea (Leatherback sea turtle)

Yokota, K., Minami, H. and Kiyota, M. Western and Central Pacific Fisheries Commission National Research Institute of Far Seas Fisheries, Fisheries Research Agency, Japan Two types of tori-lines (tori-line and tori-line light streamer) were tested aboard commercial and research longline vessels in the western North Pacific to determine their effectiveness for seabird avoidance.  The tori-line […]

Submitted by morgaac on August 30, 2012 – 17:24 One incidentally caught harbor porpoise; significant reduction in the number of porpoise clicks at nets with pingers. Pinger effects stronger at quiet sites; no habituation observed, exclusion of porpoises following pinger use for as much as 7 hrs Acoustic deterrent devices

Submitted by morgaac on November 20, 2012 – 16:39 There was a significant difference in the number of porpoise clicks between nets with and without pingers, but the extent of displacement could not be determined. No evidence of habituation to the pingers. Acoustic deterrent devices

Gearin, P.J., Gosho, M.E., Laake, J.L., Cooke, L., Delong, R.L. & Hughes, K.M. Journal of Cetacean Research and Management Pingers do not reduce bycatch of harbor seals (Phoca vitulina) in the salmon and sturgeon gillnet fisheries in northern Washington state but do reduce bycatch of harbor porpoise (Phocoena phocoena). Pingers did not affect catch of […]

Submitted by morgaac on August 30, 2011 – 15:51 The mean total attack rate was similar for each design but diving birds attacked further astern in response to both tori line types compared to surface foraging birds. The “hybrid” line did not allow attacks by divers within 50 m but the “light” line al

Submitted by lweiss on February 26, 2020 – 11:27 Large bait decreased haddock catch and caught more large species except ling. Larger hooks lowered catch efficiency but had minimal effect in size selectivity Large bait increased catch of large fish of all target species except for ling, and reduce catch of haddock. Increasing hook size […]

Fjälling, A., Wahlbergb, M. and Westerber, H. ICES Journal of Marine Science AHDs with a source level of 179 dB re 1 µPa rms at 1 m were deployed during three consecutive fishing seasons. Fish catches in traps with AHDs were significantly higher than in the controls, while catch damage in the traps with AHDs […]

Submitted by morgaac on August 25, 2015 – 10:13 Central Mediterranean Sea Reducing longline bycatch: the larger the hook, the fewer the stingrays Bait size did not have a significant effect on stingray catch rates

Ochi, D., Minami, H. and Sato, N. Western and Central Pacific Fisheries Commission Ecologically Related Species Group, Tuna and Skipjack Resources Division, National Research Institute of Far Seas Fisheries, Fisheries Research Agency. The use of blue-dyed bait (both squid and fish) as a means to reduce seabird interactions with pelagic longline fishing gear was tested […]

Sullivan, B.J., P. Brickle, T.A. Reid, D.G. Bone, and D.A.J. Middleton Three seabird bycatch mitigation measures, tori lines, warp scarer, and Brady baffler, were tested on trawlers and compared with a control treatment of no mitigation measure. Each mitigation measure reduced seabird mortalities; however, the tori lines, followed by the warp scarer, were much more […]

Robertson, G., Candy, S., and Wienecke, B. Western and Central Pacific Fisheries Commission Australian Antarctic Division, 203 Channel Highway, Kingston Tasmania, 7050 Australia Differences in sink rates of baited hooks attached to mainelines and set under varying degrees of tension, were tested aboard pelagic longlines off eastern Australia.  Three mainline configurations were tested 1. surface […]

Submitted by morgaac on January 30, 2011 – 17:41 Blue-dyed squid bait reduced subsurface interactions with seabirds by 68%. Seabirds struck only 3-8% of surface blue-dyed squid bait compared with 75-98% of non-dyed squid bait. Birds struck 48% of blue-dyed fish bait at the surface during the first tw
