Information About Author:

The article addresses changes in the fauna of the river Tom basin in the last 90 years, starting from the last century’s second decade in this work data on areas of distribution, certain size, weight and reproductive characteristics are shown. The authors discuss disappearance of pydschjan and tugun from the area. As a result of planned acclimatization efforts in the river Ob, at least 5 species were introduced to river Tom’s ichthyofauna. While in the dawn of research, salmonidae fishes were dominant species, in the present time, the basin is heavily populated by cyprinidae and percidae.
