Increasing sustainability in food production by using alternative bait in snow crab (Chionoecetes opilio) fishery in the barents sea
The use of food grade wild-captured species as bait for other fisheries questions the sustainability of food production. In pot fisheries, bait is an important factor determining the effectiveness of the gear. In snow crab (Chionoecetes opilio) fishery, the pots are normally baited with squid (Illex...
