Basing on literature and own data it was analyzed the influence of dam construction on migration roots, spawning migrations and natural reproduction of beluga Huso huso, Russian sturgeon Acipenser gueldenstaedtii, stellate sturgeon Acipenser stellatus in the Volga River resulting dam construction. It was demonstrated that decline of sturgeon natural reproduction was recouped by follows compensatory measures: ban of target sturgeon fishing in the Caspian Sea in 1951, controlled sturgeon reproduction since 1954, ban of ordinary fish species fishery in the Caspian Sea by small-mesh nets since 1962. Attempts to restore natural reproduction of sturgeon by transporting of breeders upstream the dams were not efficient resulting the loss of spawning sites
