Mink of America
The mink of America ( Mustela mink ) has the same general pace as the Vison of Europe, it is however larger (1,5 to 2 kg for the males). It is characterized mainly by the absence from clear mark on the upper lip. One finds it at the origin with the the United States and the Canada, but it was introduced in Europe and was raised for its fur. Escaped individuals then colonized the natural environments, in the countries of north (England, Belgium, Netherlands, Sweden, Finland), but also in France or Spain.
The Vison of America consumes mainly fish, small mammalian and water birds. The mink occupies approximately 2 km of banks of the rivers and it is particularly widespread in Brittany. It exploits an ecological niche near to that of his European cousin, the Vison of Europe ( Mustela lutreola ). These two species thus enter in competition, which takes part to weaken the mink populations of Europe. An experimental programme of control of mink of America is in hand in the south of the Moors with capture, tracking serologic then sterilization.
