Net-mounted LED lights help reduce bycatch in Pacific hake fishery

LED lights can help reduce bycatch by aiding the escape of Chinook salmon from Pacific hake trawl nets, according to a study done by researchers at the Pacific States Marine Fisheries Commission and the Northwest Fisheries Science Center. The lights influence where salmon exit bycatch-reducing windows in the hake nets, and could increase the total number of salmon that escape, the researchers say. In a series of tests in 2015, the lights seemed to attract the Chinook salmon. During the tests, 86 percent of the salmon that escaped used the openings framed by LED lights. click here to read the story 15:48
