Prawn / Scallop Dredging
A key issue for COAST is the detrimental impact of scallop dredging and prawn trawling to the seabed. Unlike water column fisheries these fishing techniques involve the raking of the seabed to dislodge and collect scallops and prawns. This is a destructive process that damages the complex marine habitats which are essential nursery grounds for juvenile fish. In contrast, traditional methods using lobster and prawn pots (creels) have far less impact on the seabed. Modern methods of collecting scallops by hand diving are also far less destructive, though, of course, all methods of fishing do require controls and management measures to ensure long term stocks.
