The diet was analysed from 105 European mink samples. Moreover, we collected other 37 faeces from a radiotracked European mink male. The European mink diet was based on small mammals (relative frequency of occurrences 36,9%), fish (30,6%) and birds (17,8%). The Levins index of trophic-niche width was 3,76. Wood mouse Apodemus sylvaticus was the most consumed small mammal and Cyprinids -mainly Barbus sp. was the most consumed fish. The average size and weight of consumed fish were 13,5 cm and 31,5 g, respectively and males consumed larger and heavier fish than females.

Diet composition was analysed from 85 European mink, 156 otter and 564 spotted genet fecal samples The European mink diet was based on small mammals (relative frequency of occurrences 38.1%), fish (30.9%) and birds (16.7%). Spotted genet consumed mainly small mammals, birds and fruits, whilst otter predated practically only fish (95%). Using Levins' index, trophic-niche widths in European mink, small-spotted genet and Eurasian otter were 3.76, 3.77 and 1.10, respectively. The trophic niche overlap by Pianka index for autumn-winter was 0.77 for European mink vs. Small-spotted genet, and 0.60 for European mink vs. otter. The average size of brown trout taken by otter was larger than those consumed by European mink.
