Summary Lipid composition in unfertilized eggs and in two subsequent developmental stages was studied in stellate sturgeon with eggs obtained from mature females captured in the field. Some biological information on egg incubation, the biochemical analysis and inferred calculations included components such as phospholipids, phosphatidylcholine, monoacylglycerids, diacylglycerid contents. Additionally, lysophosphatidylcholine, phosphatidylethanolamine, monoacylglycerids, diacylglycerids, triacylglycerids, cholesterol esters as well as the phospholipids/lipids ratio were determined. Approximate indices for the lipid status of stellate sturgeon eggs are given which may satisfy culture requirements.
