MacArtney Lobster Monitoring Tech for SLU
In 2009, MacArtney supplied SLU with a camera and light system that utilised direct telemetry and standard cabling for the original Lobster Sledge. A decade later MacArtney is still collaborating with SLU and has completed the co-design of the Lobster Sledge upgrade that incorporates an HD camera, LED lights, fibre optic multiplexer and interfaces. The system, designed to be towed along the seabed, collects data on the current lobster population. The data collected monitors the lobster population and informs fishing quotas for the southern coast of Norway and the Swedish coast. >click to read<08:44
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
