Stocking

Stocking refers to releases of translocated or captively raised individuals. In the Baltic Sea stocking is performed to increase commercial or sport catches of salmon, trout, whitefish, grayling, pike, pikeperch, eel, and perch.

Stocking can result in adverse genetic change to wild populations. The population genetic structure can be changed (purple box) and variation within individual populations can be changed and/or reduced which can result in loss of genetic adaptations to the local environment (red boxes).
