Sub-surface sets | Consortium for Wildlife Bycatch Reduction
Methods that reduce bycatch by eliminating gear sets at the ocean surface. These include devices such as setting chutes that place sets below the ocean surface in longline operations where they are less prone to seabird predation, and setting gillnets below the sea surface to reduce entanglement rates of small cetaceans Submitted by Jose Alio […]
Fish escape windows/separator devices | Consortium for Wildlife Bycatch Reduction
These devices are incorporated into trawl nets and are designed to give finfish openings for escape while retaining target shrimp species in the rear (codend) of the net. Examples include “skylights” which consist of a mesh opening located at the top of the codend. ”Skylights” can be combined with guiding funnels that create visual and […]
Flexible sorting grid | Consortium for Wildlife Bycatch Reduction
Submitted by morgaac on September 25, 2015 – 13:48 83.7% (weight) and 74.3% (number) of Pacific halibut were able to escape 93.3% of arrowtooth flounder, 99% of Dove sole, 96.9% of petrale sole, 96.9% of shortspine thronyhead and 90% of sablefish were retained Submitted by morgaac on September 25, 2015 – 13:21 Submitted by morgaac […]
Fishing Gear Modifications | Consortium for Wildlife Bycatch Reduction
Research and development of bycatch reduction devices. See global map of acoustic deterrent studies Incidental capture of franciscana The Consortium is testing whether ropes that have greater stiffness or fish under greater tension may be effective for reducing entanglements. The stiffness or tension would reduce the ability of the rope to bend, allowing animals to […]
Fishery Animal Interactions | Consortium for Wildlife Bycatch Reduction
Understanding interactions between non-target species and fishing operations Understanding interactions between non-target species and fishing operations Entanglement in commercial fishing ropes threatens the recovery of the North Atlantic right whale (Eubalaena glacialis), a species largely restricted waters off of eastern North America. In recent years, serious entanglements have been increasing, and mortality from conflicts with […]
