The Effect of Culture System on Proximate Composition and Amino and Fatty Acid Profiles of Peled Coregonus peled Fillets

Proximate composition and amino and fatty acid profiles of peled fillets of both sexes reared in a pond-based system (PS) and intensively cultured in a recirculating aquaculture system (RS) were compared. Significantly higher values of dry matter, fat, and caloric value were found in RS fish, irresp...

Description
Summary:Proximate composition and amino and fatty acid profiles of peled fillets of both sexes reared in a pond-based system (PS) and intensively cultured in a recirculating aquaculture system (RS) were compared. Significantly higher values of dry matter, fat, and caloric value were found in RS fish, irrespective of sex. Fish from the PS group showed a higher percentage of saturated fatty acids and polyunsaturated fatty acids (PUFA) than those of the RS group. Percentages of n-3 PUFA were lower in the RS group compared to the PS group, while percentages of n-6 PUFA were higher in RS, irrespective of sex. The ratio of n-3:n-6 PUFA was significantly higher for the RS group. Fillets of the PS group showed significantly higher EPA and DHA percentages compared to RS fish. Significant differences were found in amino acid profile, with the PS group showing higher content, especially of serine, glutamic acid, methionine, leucine, and lysine.
