Abstract

American mink (Neovison vison) originate from North America and are semi-aquatic carnivorous animals that have been bred in captivity for their fur for almost a century. In Denmark, mink is listed as an invasive species, and it is legal to hunt mink all year around.

Over the years, mink have escaped from farms, both by accident and intentionally by being let out by animal rights activists. Feral mink are widely distributed across the Danish territory. The number of mink escapes from Danish farms is currently unknown. To prevent escapes, it became mandatory to put up a fence around mink farms in 1999 and later also mandatory placing of traps and other precautions to prevent mink from escaping were introduced. The requirements have been revised latest in 2015. It has been debated whether or not there is a true feral population in Denmark and if farms in Denmark act as a source for the feral population, despite preventative laws regarding fencing and traps on the farm area.

The feral mink population consists of two groups of animals, namely mink that are born in nature and more or less adapted to a living in nature, and mink that are born on mink farms and have recently escaped into nature.

The population size of feral mink in the Danish nature is not known. However, the game bag records of mink have decreased during the past two decades. Around year 2000 the number of mink bagged was around 8000, and today less than 2000 mink are bagged (trapped and/or shot) annually.

The purpose of this project is:
• to verify if mink still escape from farms.
• to give a conservative estimate of the proportion of mink that originate from farms and have recently escaped into nature out of the total number of bagged mink.
• to investigate the reproduction, mortality and parasites of mink caught in the Danish nature.
• to test tetracycline as biomarker for mink escaped from farms


This knowledge is important in order to model the feral mink populations and to assess the efficacy of management and regulation of mink in the Danish nature.

The report contains three sections with papers to be published: 1) The use of different methods for the identification of farm escapees in feral mink populations. 2) Reproduction and mortality in wild born mink. 3) Parasites in Danish mink.
