Submitted by admin on November 1, 2007 – 12:00 There was no significant difference in the number of blue sharks caught on non-offset 16/0 and 18/0 circle hooks . Non-offset 16/0 and 18/0 circle hooks caught fewer turtles than Japanese tuna hook. Non-offset 18/0 circle hooks caught fewer turtles than non-offset 16/0 Caretta caretta (Loggerhead […]

Peckham, S.H., Lucero-Romero, J., Maldonado-Diaz, D., Rodriguez-Sanchez, A., Senko, J., Wojakowski, M. and A. Gaos S. Hoyt Peckham, Center for Ocean Solutions, Stanford University, Pacific Grove, CA, USA. E-mail: [email protected] Loggerhead sea turtles have a high-density foraging hot spot in Baja California Sur, Mexico. This spot coincides with intense bottom-set net fisheries. Controlled studies were […]

Submitted by morgaac on May 23, 2011 – 09:58 There were no significant differences in catch, catch rate or mean length for bigeye tunas. Survival was significantly higher for bigeye tuna caught on circle vs. Japanese style hooks. Catch rates on circle hooks were significantly lower than on Japanese style and “J” hooks for 16 […]

Submitted by Kate McClellan on January 17, 2012 – 15:39 Completion Report for Sturgeon Gillnet Study (number EA 133F-10-RQ-1160) Removing tie-downs decreased monkfish landings No effect on Atlantic sturgeon; increased common dolphin bycatch

Submitted by lweiss on February 13, 2020 – 12:55 giant mud crabs (Scylla serrata), blue swimmer crabs (Portunus armatus) 91-mm traps retained significantly fewer (by 42%) undersized P. armatus and A. australis. In the second experiment, fewer undersized S. serrata, P. armatus, and A. australis were retained in all larger meshed traps, and in all […]

Melvin EF, Guy TJ, Read, LB Seabird bycatch in the tuna and billfish longline fishery in South African waters has had one of the highest seabird bycatch rates in the world. Research was carried out aboard two Japanese longline vessels in the South African EEZ in 2010. Half of the branch lines on each vessel […]

Gilman, E., N. Brothers, and D. Kobayashi Final Report. U.S. Western Pacific Regional Fishery Management Council, Honolulu Underwater setting chutes, blue-dyed bait, and side-sets each reduced the bycatch of seabirds (Laysan and black-footed albatross and short-tailed shearwater) in the Hawaiian longline tuna and swordfish fisheries. Side-sets showed the most promise for a bycatch mitigation technique […]

Gamblin, C., Pascal, B. and Lucas, V. Indian Ocean Tuna Commission SFA Box 449 Victoria, Mahe Seychelles Two types of longline sets, night and day, were evaluated for differences in catch composition in Seychelles waters.  Night sets were set at dusk and retrieved at dawn and used shallow baskets targeting swordfish, while day sets were […]

Soto, A.B., Cagnazzi, D., Everingham, Y., Parra, G.J., Noad, M. and Marsh, H. Endangered Species Research Fumunda acoustic alarms were tested in the absence of nets to determine their ability to modify the behavior of Australian snubfin and humpback dolphins, with possible applications to gillnet fisheries. The alarms emitted a regular interval pulse of 300 […]

Dapp, D., Arauz, R., Spotila, J.R., and O’Connor, M.P. Journal of Experimental Marine Biology and Ecology J.R. Spotila: [email protected] An observer program assessed the impact of the Costa Rican longline fishery on bycatch species from 1999 to 2010. Observers recorded species, sex, reproductive state, and dimensions of all animals captured. They also recorded information about […]

The Consortium for Wildlife Bycatch Reduction has been working collaboratively with the Maine Lobstermen’s Association (MLA) to identify innovative fishing gears and methods that are practical for fishermen but also reduce the frequency and severity of large whale entanglements from vertical lines (ropes that extend from the ocean surface to the trap on the ocean […]

The worldwide decline in leatherback turtles has been caused, in part, by bycatch in fisheries. Leatherback turtles most often entangled or hooked externally in pelagic longline fisheries (Garrison 2003), but are capable of swimming to the surface to breathe (Witzell and Cramer 1995).  Although not all incidental captures lead to mortality, the number of leatherbacks […]
