Effect of light-emitting diodes (LEDs) on snow crab catch rates in the Barents Sea pot fishery
Abstract Snow crab (Chionoecetes opilio) has become an important species for the Norwegian seafood industry since its first commercial harvest in 2012. However, periodically catch rates can be low, causing a financial strain on the fishery. Thus, improving the catch rate of existing pot designs has...
