The small population of North Atlantic right whales is in danger of extinction. These whales were hunted nearly to extinction by commercial whalers by the end of the 1700s, but today are at risk from entanglement in fishing gear and boat strikes. At least 82% of the North Atlantic right whale population has been entangled […]

Sinking/weighted lines/baits | Consortium for Wildlife Bycatch Reduction
Changing the property of fishing lines so that they are less likely to catch or ensnare animals feeding at the surface or in the mid-water column. They include low profile line, a kind of rope linking lobster pots that might be suspended deep enough to avoid whale entanglements but with enough floatation to lie above […]
Pyrotechnics | Consortium for Wildlife Bycatch Reduction
The use of loud explosive devices, including gunshots, to scare non-target species such as sea lions away from a fishing operation. Deterrence may result from noise or tactile annoyance. Anecdotal evidence from some fishermen suggests this practice is widespread though its efficacy is not backed up by a number of studies, and it obviously threatens […]
Animal predation sounds | Consortium for Wildlife Bycatch Reduction
Audio recordings of an animal in distress, or of its predator, played to deter individuals of that species from entering into a fishing area. Jefferson and Curry (1996) concluded that this technique was largely ineffective for reducing marine mammal interactions with fishing activity based on their review of multiple studies. Submitted by admin on November […]
Sea exclusion devices in cod pots prevent seal bycatch and affect their catchability of cod | Consortium for Wildlife Bycatch Reduction
Konigson, S., Lovgren, J., Hjelm, J., Ovegard, M., Ljunghager, F., Lunneryd, S. [email protected], [email protected] Experiments were conducted along the Swedish coast to investigate the impact of seal exclusion devices (SEDs) on seal bycatch. Pot entrances were fitted with SEDs of different shapes and sizes. The pots were a two-chambered single entrance floating cod pot. Pots […]

Reducing bycatch with better technology in the Gulf of California shrimp fishery; Final technical and financial report to the Walton Family Foundation, submitted by World Wildlife Fund | Consortium for Wildlife Bycatch Reduction
Aguilar-Ramirez, D. and Rodriguez-Valencia, J.A. Bycatch reduction device prototypes (“RS_INP”) (industrial and artisanal versions) were tested on vessels targeting shrimp in the Gulf of California to compare bycatch-to-shrimp ratios, catch efficiency, drag resistence indicators, fuel consumption rate and selectivity with traditional versions. The industrial version of the prototype reduced bycatch-to-shrimp ratios from 20-50% and shrimp […]
