METHOD OF ESTIMATING REPRODUCTIVE POTENTIAL OF STURGEON SPAWNERS Russian patent published in 2008 - IPC A01K61/00 

FIELD: agriculture, fishery.

SUBSTANCE: invention refers to the sphere of fishery and deals with selection of spawners immediately at the fishing grounds with a view of providing for the needs of breeding, as well as formulation of forecasts concerning the reproductive potencial of natural population spawners. The method consists in selecting spawners on grounds of blood values and establishing mathematical correlation between blood values and fertility. Spawners are selected from among the fish natural population, the fertility being estimated based on mathematical correlation between its value and γ-globulin content in their blood plasma with the help of formula: Y=84.181-17.296x+1.473x²-0.03001x³, where Y = spawn potential fertility, %; x - proportional content of γ-globulin in their blood plasma, %. The method provides for evaluating the efficiency of sturgeon fish breeding in the natural habitat and selection of spawners immediately at the fishing grounds with a view of providing for the needs of breeding.

EFFECT: providing for evaluation of the efficiency of sturgeon fish breeding in the natural habitat and improving artificial reproduction efficiency.

EFFECT: 1 dwg
