Understanding and predicting the effect of entrance cone diameters on the catch efficiency of snow crabs ( Chionoecetes opilio ) in conical pots
Conical pots with a plastic entrance cone on the top are a type of fishing gear used to harvest snow crabs ( Chionoecetes opilio ) in Arctic regions. In this study, we assessed the effect of pot entrance diameter on the catch efficiency of snow crabs. We used catch data collected during sea trials o...
