The levels of nitrogen and phosphorus in the Baltic Sea have to decrease in order to limit eutrophication. In a marine context nitrogen fixation and harvesting of mussels is often discussed as a method to reduce nutrient levels. But commercial fisheries also have the potential to reduce eutrophication in the Baltic Sea by catching fish that contains nutrients.
The project aims to estimate the economic value of removing nutrients from the Baltic Sea by fishing. Different fisheries in Denmark, Sweden and Finland are analysed to investigate how an economic compensation would affect the economic performance of the fisheries. A bio-economic model will be used where the effect of a compensation will be analysed under different scenarios.
