This paper focuses on the availability of economic indicators and metrics to assess effects of marine aquaculture production in the North Atlantic area (the EU, Nor-way, Canada and USA), including also social and environmental effects. We con-sider how aquaculture planning and management is organised in the different countries and the usefulness of economic information to address different aqua-culture-related policies. We find that the most relevant economic data for aqua-culture management should be at the local and regional levels rather than nationally. The availability of such economic data is mapped for national, regional and local level. The focus is on data that are publicly available from authorities or research institutions. The availability of data is generally fairly good for national and regional data on the direct economic effects of aquaculture. Data on how aquaculture-related products or input markets are affected are however poorly available, as are economic data on external effects from aquaculture. Countries with a larger aquaculture sector tend to have better availability of aquaculture-re-lated economic data than those with a smaller sector. An index is developed and calculated to show more specifically where the countries have relatively good or poor data availability compared to their needs. While it will not always be cost-ef-fective or meaningful to collect economic data on the effects of aquaculture, our study indicates that several countries could benefit from expanding such data col-lection. It can make trade-off decisions more consistent and easier to perform, and aquaculture policies and measures can be better tailored to specific contexts.
