Fatty acid composition in sturgeon caviar from different species: comparing wild and farmed origins

The fatty acid compositions of both lipid classes, triglycerides and phospholipids, of caviar from 34 specimens of wild caught and 12 farmed specimens were measured. The investigated caviar samples of wild caught sturgeon comprised Huso huso, Acipenser gueldenstaedti, Acipenser stellatus and Polyodon spathyla of different origins and those of farmed sturgeon from Acipenser baeri, A. stellatus and A. spathula.
