Socio-economic importance of nitrogen nutrient load in the environment

image of Nordic fisheries and aquaculture

This report contributes to the understanding of how the the socio-economic contribution of Nordic fisheries/aquaculture are affected by the environment and environmental management, with focus on nitrogen. The report contains two case studies of how the socio-economic contribution of Danish/Swedish cod fishery in the Western Baltic Sea are affected by the nitrogen in the sea, and on how salmon growth rates in aquaculture in the Bokna Fiord are affected by nitrogen concentration. A Nordic workshop was held with the title: Fisheries, aquaculture and the marine environment: Environmental challenges and regulation, with focus on nitrogen. The finding of the case studies was presented at the workshop, together with presentations made by invited speakers on the role of nutrients and their management for Nordic fisheries/aquaculture. The discussion at the workshop is summarized in this report.

Conclusions

In this report, the Socio-economic importance of nitrogen nutrient load in the environment for Nordic fisheries and aquaculture was analyzed and discussed. The management perspectives of the interactions between fisheries and aquaculture on the one hand, and the environment on the other, were also discussed. It was found that nitrogen and nitrogen management is important in the Baltic Sea, but no indications of substantial problems were identified elsewhere in the Nordic area. The interaction between fisheries and aquaculture on the one hand, and nitrogen management on the other, appear mainly of importance in the East Nordic area in Denmark, Finland and Sweden. The report further points towards the option to develop cleaning actions in the form of removal of nutrients in fish caught and by breeding mussels and seaweed.
