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

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

Submitted by morgaac on August 28, 2010 – 09:13 Crab catch rates were 9% higher when the 4.5X10 excluder design was used and crabs were of similar sizes in the two traps (modified and unmodified) Modified traps with a 4.5X10 cm frame caught no terrapins compared to the 22 caught in the unmodified traps Trap […]

Dealteris Associates Inc. to NMFS NEFSC Leaders in offshore, deep water pound nets in the Virginia portion of Chesapeake Bay incidentally take protected sea turtles. To reduce this take, federal resource managers restricted the use of traditional leaders during periods of peak sea turtle strandings. In response to these restrictions, a modified leader was developed. […]

Lomeli, M.J.M., Wakefield, W.W. Pacific States Marine Fisheries Commission (PSMFC), 2032 SE OSU Drive, Newport, OR 97365, USA, [email protected] The Pacific hake (Merluccius productus) midwater trawl fishery is the largest groundfish fishery off the U.S. West Coast by volume. However, bycatch of Chinook salmon can be an issue as Endangered Species Act (ESA)-listed Evolutionarily Significant […]

Submitted by morgaac on July 11, 2011 – 14:43 Reduced the proportion of soft and damaged prawns by 35.8% and reduced catches of tiger prawns by 6.3% Upward facing TED’s reduced sea turtle bycatch by 99%

Sullivan, B.J., Kibel, P., Robertson, G., Kibel, B., Goren, M., Candy, S.G. and Wienecke, B. At-sea and on-shore trials were conducted to test the safety and effectiveness of an alternative line weight called the Safe Lead.  This new line weight is designed to reduce danger to the crew in the event of a bite-off by […]

Richards, R.J., Raoult, V., Powter, D.M. and Gaston, T.F. School of Environmental and Life Sciences, University of Newcastle, NSW, Australia The potential benefits of permanent magnets on ocean fish traps targeting snapper (Pagrus auratus) and their abiliy to reduce elasmobranch bycatch. The study deployed over 1000 traps in a fishery-dependent survey in New South Whales, […]

Gilman, E., Chaloupka, M., Wiedoff, B., Willson, J. e84499. doi:10.1371/journal.pone.0084499 The Hawaii longline swordfish fishery reduced seabird captures through mitigating bycatch during setting. Now, 75% of bycatch occurs during hauling. Observer data was fit to a generalized additive regression model and found that density of albatrosses during hauling, leader length, and year had the largest […]

Submitted by morgaac on February 12, 2011 – 08:12 Weighted longlines had a slightly higher overall CPUE (1.3 fish/100 hooks) compared to traditional longlines (1.08 fish/100 hooks) and caught more bigeye (0.95 fish/ 100 hooks) than traditional longlines (0.56 fish/100 hooks). Catch rates were not very

Beverly, S., Curran, D., Musyl, M. and Molony, B. Tests were conducted in the Hawaii-based tuna longline fishery to determine if removing the shallowest hooks from pelagic longline sets would maximize the catches of target species while minimizing the incidental catch of non-target species.  Catch rates of bigeye tuna were not significantly different between the […]
