Population structure and connectivity in the genus Molva in the Northeast Atlantic
Abstract In fisheries, operational management units and biological data often do not coincide. In many cases, this is not even known due to the lack of information about a species’ population structure or behaviour. This study focuses on two such species, the common ling Molva molva and the blue lin...
