| Abstract |
The past and present of fish faunas within the borders of the USSR are considered. In most regions, natural faunas have become locally improverished and in many regions new faunas have formed, indluding both native and introduced species. It seems evident that there can be no singke universal strategy of fish fauna protection for the USSR or for other 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 regions preserved their faunas. Introductions of non-native species can be unavoidable but they should have a solid scientific basis. Thorough faunistic, ecological, and genetic studies of fishes in the USSR are urgently needed. |
