Stocking refers to the release of translocated, or captively raised individuals. In the Baltic Sea stocking is used to increase commercial or sport catches of e.g. salmon, trout and whitefish. Stocking can reduce or alter the genetic diversity of the wild populations, which in turn will affect their potential to adapt to environmental change and their long term survival.

General recommendations

  • Avoid stocking. Instead consider proper management of the wild populations to maximize their productivity.
  • Stocking should only be used for conservation purposes to replace a lost population or to support a weak one. Only use individuals from closely related populations.
