Mink farming for fur production has been banned in a growing number of countries following welfare assessments that conclude minks' semi-aquatic, ranging needs cannot be met in caged systems.
Mink farming presents a case study in species-specific welfare failure. Unlike domesticated species that have adapted to confinement over centuries, farmed mink retain their wild behavioral repertoire - including the need to swim, hunt, and range. The impossibility of meeting these needs in a commercial cage environment is reflected in the consistently high prevalence of stereotypic behaviors, which represent chronic behavioral frustration. Welfare assessments in multiple countries have concluded that meaningful welfare cannot be achieved within a commercial fur farming model - a conclusion that has driven legislative bans. The animals' experience in these systems constitutes chronic deprivation of fundamental behavioral needs.
