BRD

April 27, 2018 by abby

BRD is an acronym for bycatch reduction device.  Bycatch is non-target catch within any fishery. For certain fisheries, these modifications to the gear (i.e., BRDs) can help lower the amount of bycatch.  For example, a turtle excluder device (TED) is a specific type of BRD designed to help turtles escape trawl nets.  Especially in cases where fisheries have bycatch … [Read more…]

Turtle Excluder Devices (TEDs) are a specific type of bycatch reduction device (BRD) that are a modification to a trawl net to keep turtles, which are not targets of the fishery, from being caught in the net.  TEDs are generally composed of a set of bars over the trawl net.  While small target animals, such … [Read more…]

Bycatch is non-target catch within any fishery.  Bycatch can be either different species from the target of the fishery or individuals from the target species, generally juveniles, which are not of a marketable size.  Most bycatch is tossed back because it is illegal to possess or it has no commercial value.  In certain fisheries, however, … [Read more…]
