[A comparison of the spawning migration and genetic and biological parameters of stellate sturgeon from the Volga population in 1985 and 1996].

The dynamics of changes in several genetic and biological parameters of the Volga stellate sturgeon during the spawning runs of 1985 and 1996 were studied by electrophoresis and morphometry and compared. The dynamics of changes in genetic diversity of the spawners running spawners is repeated in many respects every 11 years, suggesting that the intrapopulation diversity is maintained in time. The among-sample diversity of late spring stellate sturgeon, whose spawners spawners are used in hatchery, decreased twofold.
