Mink farming has been banned in over a dozen countries on welfare grounds, with scientific evidence showing that the welfare needs of semi-aquatic mustelids cannot be met in commercial farming systems.
The welfare science underpinning mink farming bans is robust. Studies across multiple countries consistently document high prevalence of stereotypic behaviour - particularly repetitive swimming motions and head-weaving - as indicators of thwarted natural behaviour. Mink are solitary territorial hunters that in the wild range over several kilometres; in cages of around 0.25 square metres they cannot express fundamental species-typical behaviours. Water access for swimming is rarely provided. The scientific consensus is that no economically viable mink farming system can meet the welfare needs of this species, leading welfare scientists to support complete bans.
