Abstract

The past and present of fish faunas within the borders of the USSR are considered. In most regions, natural faunas have become locally impoverished and in many regions new faunas have formed, including both native and introduced species. It seems evident that there can be no single universal strategy of fish fauna protection for the USSR or for other vast administrative areas. Protective measures should be designed for natural regions (big lakes or river basins) within which damaged fish communities could be restored under favourable conditions if some subregions preserved their faunas. Introductions of non-native species can be unavoidable but they should have a solid scientific basis. Thorough faunistic, ecological, and genetical studies of fishes in the USSR are urgently needed.
