April 5, 2016 — Bycatch is a huge problem for the US shrimp industry, which is under pressure to reduce the unintended entrapment of marine species. Devices that deflect turtles and help fish avoid or escape the nets have been necessary for years, and federal law requires nets to be fitted with devices that reduce bycatch by 30 per cent but despite this, the amount of bycatch is still about three times that of the targeted shrimp (North Carolina Wildlife Federation).
A report released by the North Carolina Wildlife Federation described the amount of bycatch in the state as being unsustainably high and unacceptable at about three times that of the targeted shrimp.
But North Carolina’s shrimp industry is huge — fishermen harvested 14.1 million US dollars worth of shrimp in 2014, and nearly 200 commercial fishermen currently work in the industry.
In light of the bycatch, North Carolina is now taking steps to find a solution. In 2015 the North Carolina Marine Fisheries Commission established a group of fishermen, net makers, researchers, fish dealers and other stakeholders who gather and evaluate information on the effectiveness of various bycatch reduction devices or BRDs.
Among those tested are the composite panel with spooker cones (a cylindrical shaped device used to spook or scare fish to seek escape), additional escape openings called fisheyes and tailbags, also known as codends, the portion of the net that holds the shrimp catch.
