Application of Luminescent Netting in Traps to Improve the Catchability of the Snow Crab Chionoecetes opilio
Abstract In this study, we investigated luminescent netting as a means to improve the catch rates of snow crabs Chionoecetes opilio . A laboratory experiment was conducted to investigate the intensity and duration of luminescence using time‐lapse photography. We exposed experimental traps to five di...
