Abstract :
The aim of this research was to compare the nutritional value, biochemical composition and fatty acid profile of farmed and wild Sturgeon fish (Huso huso) fillets in Mazandaran province. For this purpose, 3 farms were selected in the cities of Sari, Babolsar, and Behnemir, and 10 fish were caught from each, and 30 Sturgeon fish were caught from three fishing centers in the Caspian Sea, which were transferred to the laboratory following the cold chain. After preparing the samples, the tests of crude protein, total fat, moisture and ash, fatty acid profile were performed and each test was repeated 3 times. For data analysis, Anova and Duncan's test were used to identify significant differences between the data. The results of this research showed that the analysis of the biochemical composition of farmed and wild Sturgeon fish carcasses, moisture content, total fat, total protein and ash did not have any significant difference (p>0. 05). The amount of total saturated fatty acid (SFA), total amount of monounsaturated fatty acid, total amount of polyunsaturated fatty acid (PUFA) and the comparison of total polyunsaturated fatty acid to total saturated fatty acid (PUFA/SFA) in wild fish were significantly higher than farmed fish. (p>0.05). According to the results of this research, it was found that farmed fish is equal to wild fish in terms of nutritional value.
