In our research we study of the correlation between the biochemical composition of unfertilized sturgeon caviar and the results of its incubation. We studies besters (bester is a hybrid of beluga and sterlet) and stellate sturgeon caviar. We find out that for both bester and stellate sturgeon, the dependence of the fish breeding quality of eggs on the lipid composition was identical. It was shown that the lipid composition of caviar has the greatest influence on the fish breeding qualities of caviar. Also it was shown that such biochemical characteristics of the caviar as protein level does not correlate with fish breeding quality of the caviar. The recommendations to use the caviar with high level of the ratio phospholipids/total lipids and high level of phosphatidylcholine and low level of monoacylglycerols, diacylglycides or lysophosphatidylcholines for artificial reproduction were made.
