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 […]

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 […]

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 […]

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

Submitted by morgaac on May 13, 2016 – 09:16 Acoustic investigation of bycatch mitigation pingers The current net/pinger configuration is adequate for humpback whales, dugongs and dolphins swimming at normal travelling speeds. The current pinger spacing is insufficient for dolphins swimming straight at the net at high speeds. Acoustic deterrent devices

Bolten, 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) caught significantly more blue sharks than J hooks in the Azores longline swordfish and blue shark fisheries.

Submitted by morgaac on February 8, 2011 – 14:29 Efficiency of the circle hook in comparison with J-hook in longline fishery Target species catch rates were higher on circle hooks (2.2 individuals/1,000 hooks) compared to J-hooks (1.9 individuals/1,000 hooks). Swordfish caught by J-hooks were slightly larger than those caught on circle hooks. J-hooks caught a […]
