The distribution of Diplostomium phoxini (Faust, 1918) (Trematoda: Diplostomidae) metacercariums in the minnow populations from the Yenisey and Kacha rivers

For the first time distribution research of Diplostomium phoxini metacercariums - a specific parasite of fishes of a g. Phoxinus- in age structure of minnow population from the rivers Yenisey and Kacha within one geographical area is conducted. Extensiveness of invasion and index of an abundance of a parasite naturally increases with the years the owner in both populations. An abundance index of metacercariums at a minnow from the river of Kacha 10 times more in comparison with its population from the river Yenisey.
