Diet of the American mink (Mustela vison) in the Czech Republic (Carnivora: Mustelidae) [Potrava norka amerického (Mustela vison) v České republice (Carnivora: Mustelidae)]
Michaela Nováková, Petr Koubek
An analysis of 29 full stomachs of the American mink (Mustela vison Schreber, 1777), collected in the Křivoklátsko Protected Landscape Area and in the Horažďovice region (Czech Republic) during autumn and winter time in 2001–2006, showed a great diversity of the mink diet. Fish (Cyprinidae, Percidae, and Esocidae) were the dominant component of their diet (51.7% of occurrence, 41.0% of volume), followed by mammals (Rodentia, Insectivora) (48.7% of occurrence, 31.1% of volume) and birds (20.7% of occurrence, 13.2% of volume). Amphibians, insects, carrions and plants served only as supplementary food. Mink was found to be a typical generalist predator. Mink diet is, most probably, influenced by prey availability, prey behaviour, season, prey abundance and habitat type.
