Tracking the migratory success of stocked European eels Anguilla anguilla in the Baltic Sea
To investigate the extent to which European silver eels Anguilla anguilla , originating from stocking programmes in the Baltic Sea tributaries, effectively contribute to the spawning stock, two hundred and seventy‐four formerly stocked A. anguilla. emigrating from the Schwentine River near Kiel, Ger...
