Ocean Associates, Inc., in collaboration with the Consortium for Wildlife Bycatch Reductionand with funding from the National Marine Fisheries Service Office of International Affairs andSeafood Inspection, is pleased to announce the availability of grants to support capacity buildingfor reducing marine mammal bycatch.The kinds of projects eligible for support can include:1) Evaluation of potential marine mammal […]

Bycatch is one of the greatest and best-documented threats to cetaceans globally (Reeves et al., 2005). In the Indian Ocean, cetacean bycatch is known to be high, yet there are huge gaps in our existing knowledge on the extent to which bycatch poses a threat to cetaceans in this region (Kiszka et al., 2009; Anderson […]

Clarke, T.M., Espinoza, M., Ahrens, R. and I.S. Wehrtmann The elasmobranch assemblage associated with the shrimp trawl fishery operating along the Pacific coast of Costa Rica was assessed. Trawl hauls were conducted between August 2008 and August 2012, resulting in the sampling of 4,564 elasmobranchs from 25 species and 13 families. The most commonly caught […]

GIlman, E., Chaloupka, M., Swimmer, Y. and S. Piovano A literature review of 30 studies was conducted to determine the  effectiveness of various bycatch reduction devices for elasmobranchs. The risk of capture was 1.2 times higher on circle hooks but haulbaulk mortality as well as deep hooking was reduced. Wire leaders had higher shark catch […]

Australian Fisheries Management Authority PO Box 7051 Canberra BC ACT 2610 Tests were conducted to determine if twin trawl nets containing a Turtle Excluder Device (TED) and a Popeye Fishbox caught less bycatch then nets fitted only with a TED. Nets that had the Popeye Fishbox located 70 meshes from the codend draw strings had […]

The National Marine Fisheries Service (NMFS) determined that the scalloped hammerhead shark (Sphyrna lewini), an Atlantic highly migratory species (HMS), is overfished (NOAA 04/28/2011).  This finding is based on a stock assessment of the population in US Atlantic waters published by Hayes et al (2009) in the North American Journal of Fisheries Management.  His study, completed […]

[email protected] Alaska Fisheries Science Center National Marine Fisheries Service Groundfish trawl nets were fitted with a rigid grate in an effort to exclude Pacific halibut while retaining the target species.  The grate was placed in front of the trawl codend, which allowed the target species to pass through while Pacific halibut escape.  Escape rates of […]

Bycatch mitigation is a central focus of the New England Aquarium’s sustainable fishing initiative. In 2005, the Aquarium helped found the Consortium to reduce bycatch in threatened non-target animals. The Consortium supports collaborative research between scientists and the fishing industry to develop practical techniques that reduce or eliminate bycatch of endangered or threatened species. Boston, Massachusetts […]

Field project report – New England Aquarium Short term behavioral responses of Chilean dolphins (Cephalorhynchus eutropia) to acoustic alarms, or pingers, were tested using exposure-control experiments (pinger on/off treatments). Field trials were conducted in the south-eastern Chiloe Archipelago  between February and April of 2013. BananaBP154 pingers (FishTek Marine) were used for the tests. Static passive […]
