Comparative Analysis of Nutritive Composition, Fatty Acids, Amino Acids and Vitamin Contents of Wild and Cultured Gilthead Seabream (Sparus aurata L. 1758)

In this study, nutritional value, fatty acids, vitamin and amino acid contents of cultured and wild gilthead scabream (Sparus aurata L. 1758) were comperatively investigated. Fat and moisture contents of the wild type and cultured fish were 69.810 +/- 0.046-68.38 +/- 0.020 and 8.7 +/- 0.030-10.10 +/- 0.050%, respectively and the difference was statistically significant (p<0.05). However, difference in protein content of both wild and cultured fish (18.880 +/- 0.080 and 19.0 +/- 0.050%, respectively) was insignificant (p>0.05). Aspartic asit, threonin, serine, glutamic asit, valine, methionine, isoleucine, leucine, tyrosine, histidine and arginine content were significantly higher (p<0.05) in wild fish, wheras proline, glycine, alanine, phenylalanine and lysine were significantly higher (p<0.05) in cultured fish. Vitamin A content was significantly higher in cultured fish (p>0.05), however, vitamins E and B, were abundant in wild fish as compare to the cultured fish (p>0.05). Of monounsaturated fatty acids, oleic and palmiteloic acid contents of both cultured and wild gilthead seabreams were insignificant (p>0.05), whereas linoleic acid content was higher in cultured fish (p<0.05). As for the polyunsaturated fatty acids, alpha-linolenic acid and eicosanoic acid contents were insignificant in both cultured and wild fish. However, Docosaheksaenoic (DHA) ve Eicosapentaenoic (EPA) acid contents were significantly higher in cultured gilthead seabreams (p<0.05).
