Implications of defining fisheries closed areas based on predicted habitats in Shetland: A proactive and precautionary approach
During 2010 a set of 22 voluntary closed areas, distributed around Shetland, were proposed by local industry in order to help protect and conserve threatened habitats from potential physical disturbance from scallop dredging. Initially, closed areas were implemented on a precautionary basis over pre...
