Macroalgae—Technical support for new principles of management in mussel fishery (39090)

Project Details


The main purpose of the study was to provide knowledge on key ecosystem components, with special emphasis on macroalgae in Natura 2000 areas in Limfjorden in order to improve the scientific basis for management of shellfish fisheries. In addition, effects of closing areas for shellfish fisheries on benthic vegetation were studied by comparing coverage of macroalgae and eelgrass in two adjacent areas, one of them having been protected from fisheries for the last 20 years.

Primary method was monitoring through video surveys to create a description of seabed composition, existing habitats and coverage of macroalgae and eelgrass. Approximately 800 recordings were performed covering 5 broads in Limfjorden.

This project was coordinated by DTU Aqua and funded by the Danish Ministry of Food, Agriculture and Fisheries and the European Fisheries Fund
