Bycatch reduction device : ウィキペディア英語版
Bycatch reduction device
In the fishery business, a bycatch reduction device is a tool designed to minimize unintended capture (or bycatch) of marine animals, thus reducing the adverse effects of fishing on the ecosystem.
== Development ==
To minimize accidental capture of marine animals, National Oceanic and Atmospheric Administration (NOAA) fisheries developed and tested bycatch reduction devices (BRDs). These devices are openings in shrimp trawl nets that allow finfish or other unwanted aquatic animals to escape, while the target species, such as shrimp, is directed towards the tail bag or cod end of the net. The placement and design have been developed in conjunction with normal bottom trawling practices, using trawl nets outfitted with a turtle excluder device. BRDs are required in shrimp trawl nets working in the federal waters of the Gulf of Mexico and South Atlantic regions.
