Abundance and Distribution of Elasmobranchs in NAFO Regulatory Area (Divisions 3MNO) (Elasmobranch Fisheries – Oral)
Recently, the importance of elasmobranch fisheries has increased in the NAFO area due to the collapse of some important stocks like cod or American plaice; species like thorny skate are now one of the main resources in the NAFO Regulatory Area, especially in the Grand Bank. Nevertheless, in Flemish...
