Mussel production and water framework directive targets in the Limfjord, Denmark: an integrated assessment for use in system-based management. Ecology and Society 16(4): 26. https://doi.org/10.5751/ES-04259-160426
Highlights
Coastal systems throughout the world suffer from rapidly increasing anthropogenic pressures, and integrated management solutions are required to ensure sustainable use of resources (Moksness et al 2009)
This study focuses on the usefulness of a System Approach Framework (SAF) implementation for stakeholder understanding of complex systems and development of sustainable management
Simulation of mussel fishery closures resulted in a tenfold increase in the hitherto fishable mussel biomass and a similar decrease in the biomass of shallow-water mussels and medium-sized ones in deep water
Summary
Coastal systems throughout the world suffer from rapidly increasing anthropogenic pressures, and integrated management solutions are required to ensure sustainable use of resources (Moksness et al 2009). In European coastal waters, eutrophication caused by nutrient leaching from arable and urban areas threatens both ecosystem health and opportunities for important economic development. The concurrent increase in blue mussel (Mytilus edulis) biomass supported a thriving mussel fishery, which became the largest harvest yield from the fjord (Hoffmann 1994, 2005). In recent years mussel biomass and harvest have decreased with a decrease in nutrient loadings. With national implementation of the European Union’s Water Framework Directive (WFD), further reductions in nutrient loadings are required, giving rise to more concern from mussel producers who anticipate continued diminishing resources. With further decreases in nutrient loading, there is concern for the future of this industry as well as for increasing conflicts between mussel fishers and mussel farmers
