Ghost fishing efficiency by lost, abandoned or discarded pots in snow crab ( Chionoecetes opilio ) fishery
Marine pollution by lost, abandoned or otherwise discarded fishing gear (ALDFG) often has negative impact on the ecosystem through plastic pollution and continuous capture of marine animals, so-called “ghost fishing”. ALDFG in pot fisheries is associated with high ghost fishing risk. The snow crab (...
