Abstract: Fillet yield, colour, chemical composition and fatty acid composition in the reciprocal hybrid (SSZ) of Siberian sturgeon with its crossbred with green sturgeon were analysed. It was found that fillet yield in relation to the weight of gutted and deheaded carcass did not deviate from the parent forms. SSZ does not keep the salmon-pink colour of tissue, which is typical of the father form. Its tissue contains more (P ≤ 0.01) protein and less (P ≤ 0.01) water than the parental tissue as well as less (P ≤ 0.01) fat than the father's tissue. The percentage of MUFA in tissue lipids corresponds to their proportion in the father form, whereas the corresponding values for SFA and PUFA are closer to the father form and much higher (P≤ 0.01) than in the mother form. A 100 g portion of the SSZ tissue for consumption contains a higher total amount of n-3 acids as well as EPA and DHA than the parent fish, with a higher difference in comparison with Siberian sturgeon.
