Abstract Eutrophication of coastal waters is a serious environmental problem with high costs for society globally. In eastern Skagerrak, reductions in eutrophication are planned through reduction of nitrogen inputs, but it is unclear how this can be achieved. One possible method is the cultivation of filter-feeding organisms, such as blue mussels, which remove nitrogen while generating seafood, fodder and agricultural fertilizer, thus recycling nutrients from sea to land. The expected effect of…

Mussel production as a nutrient mitigation tool for improving marine water quality
: Longline mussel farming has been proposed as a tool to remove nutrients and counteract the negative effects of eutrophication in coastal waters. In this study, we use coupled 3D hydrodynamic and
Mussel farming as a nutrient reduction measure – a case study in Limfjorden , Denmark
  • Environmental Science

This study aims to understand the economic and bio-physical conditions under which mussel farming is a cost-effective mitigation measure for improving water quality related to excess nitrogen in
The use of shellfish for eutrophication control
Effects of excess loading of nutrients to the marine environment can be mitigated by mussel cultures, basically through nutrient removal from the marine environment when shellfish are harvested.
Blue Oceans with Blue Mussels - Management and planning of mussel farming in coastal ecosystems
Eutrophication is one of the largest and most serious global threats to the marine environment. The effect of eutrophication has become increasingly clear during recent time, and major economic and

It was showed that the value of mussel farming depends on the cost at the farm, and the impact on the mean and variability of nutrient removal in relation to other abatement measures, with it found to be lower for countries equipped with highly productive mussel farms and long coastlines.
Role of Shellfish Aquaculture in the Reduction of Eutrophication in an Urban Estuary.
Oyster "bioextraction" of nutrients and how oyster aquaculture might complement existing management measures in urban estuaries was examined in Long Island Sound, Connecticut, finding that this up-scaled local-scale method could be useful in bodies of water without circulation models.


Recycling of macronutrients from sea to land using mussel cultivation
The presence of diarrheic shellfish toxins (DST) has been the main obstacle to mussel cultivation in Sweden. Monitoring of DST concentrations in mussels by HPLC for 12 years has shown great
Controlled Eutrophication—Increasing Food Production From the Sea by Recycling Human Wastes
Eutrophic systems, on the other hand, rarely achieve the status of a stable, climax community. The continuous supply of nutrients to these environments sustain high levels of photosynthetic
European mussel cultivation along the Atlantic coast: production status, problems and perspectives
Development of sustainable mussel culture in Europe has different requirements for traditional and for new areas, and in new areas the main problems are harmful blooms, local productivity and development of markets.

The principle factors affecting the contamination of shellfisheries were season, high/low tidal cycle and rainfall, and the effects varied between harvesting areas and between individual sampling points within harvesting areas.
A multidisciplinary approach to evaluating impacts of shellfish aquaculture on benthic communities
The impact of suspended mussel culture on the benthos of a small Nova Scotia cove was assessed using meehods involving both benthic metabolism and community structure, and there is a shift toward anaerobic metabolism at the mussel lines, the impact of mussels falling to the sediments was more noticeable in benthics community structure than was any impact due to organic sedimentation or hypoxia.
