The values of biological parameters by the fingerlings of hybrid between Russian sturgeon and stellate bred in reservoirs supplied with the artesian water in aspect of comparison with the fingerlings of Russian sturgeon bred in analogical conditions are presented in this article. The mass of body, zoological length of body according to the database of control fishing for which were determinate middle values, coefficient of variation, modal, medianal values also asymmetric and excess of them were presented from biological parameters. The equations of regression of growth by mass and zoological length of body of fingerlings of hybrid between Russian sturgeon and stellate and of the mother form are given. The graphics of growth of mass of body and the zoological length of body, the temp of growth of values of these parameters, the dynamic of values of minimal and maximal mass of body, of feeding coefficient of the fingerlings by hybrid between russian sturgeon and stellate and the russian sturgeon in aspect of comparison are presented. The conclusions in which was marked that at the end of stage of rearing the fingerlings of hybrid between Russian sturgeon and stellate showed most growth than the fingerlings of Russian sturgeon by almost same value of feeding coefficient are given. We may consider this phenomenon like the effect of heterosis.
