Mink Impact on Salmon Welfare | Animal Welfare Hub

American mink in British rivers prey on Atlantic salmon parr, adding another pressure to already declining populations with welfare implications for individual fish.

Key Facts

Mink escaped from fur farms have colonised most British waterways since the 1970s
Salmon parr (juvenile fish) are vulnerable to mink predation in shallow river sections
Mink predation effects are difficult to separate from other salmon population pressures
Mink control in river catchments is part of integrated salmon and water vole conservation
Mink are particularly active at dawn and dusk when parr are most vulnerable

Welfare Considerations

Mink predation on salmon parr represents both an ecological and welfare harm: individual parr killed by mink experience the acute welfare harm of predation; the population-level effect adds to the multiple stressors already threatening wild Atlantic salmon. In fragmented, already-depleted salmon populations, mink predation may tip population dynamics toward local extinction. Mink control as part of integrated river management protects both salmon welfare and population viability, with the same caveat that control methods must be humane.
