Trends in coastal fish stocks of the Baltic Sea
Coastal fish monitoring with multi-mesh gill nets and gill net series is carried out in eleven areas around the Baltic Sea. The purpose of the monitoring is to reveal population status and elucidate long-term trends of fish population and community development. Time series cover 9–20 years of annual...
