Estimation of the Age and Reproductive Performance of Wild-Born and Escaped Mink (Neovison vison) Caught in the Wild in Denmark

The feral mink population in Denmark consists of two groups animals: born the wild and that have recently escaped from farms. aims this study were to: (1) estimate reproductive performance mortality Danish (wild-born) farms (captive-born); (2) discuss likelihood a self-sustaining wild-born Denmark; (3) model relationship between pulp cavity width age mink. During 2018, 247 caught sent for necropsy at National Veterinary Institute. Based on body length, 112 determined as captive-born 96 wild-born. mean litter size ± SE females was 7.6 0.9 (range: 5–11 kits) 5.9 1–10 kits). (in months) highly significant. Individuals with >35% younger than one year. fecundity, turnover estimated to be 66%, yearly 69%. Hence, is slightly declining. In conclusion, reproducing persists without continuous influx
