The structure of fish assemblages and fish stocks is studied using standard multimesh gillnets in the annual monitoring program in different parts of the Baltic Sea. Other contributing partners are Sweden, Estonia, Latvia and Lithuania and HELCOM. The monitoring areas in Finland are Brunskär (Archipelago Sea) since 1992, Helsinki and Espoo sea area and Tvärminne since 2005 (Gulf of Finland). Goals Long-term changes in the fish assemblages that reflect the state of the coastal waters are monitored in collaboration with other Baltic Sea countries and HELCOM. Impact of research The monitoring program produces information on those fish stocks that are not targeted by commercial or recreational fishing. The program is useful in the development of indicators describing the state of the Baltic Sea e.g. in connection with the Marine Strategy Directive.
