Potential Enhancement of Proximate, Fatty Acid, and Amino Acid Compositions through the Hybridisation of Pangasianodon hypophthalmus (Sauvage, 1983) (♀) and Pangasius nasutus (Bleeker, 1976) (♂)

Abstract

| This study investigated the biochemical composition of a hybrid, crossbred between Pangasianodon hypophthalmus (PH) (♀) and Pangasius nasutus (PN) (♂), denoted as hybrid PH×PN, in comparison to its parents’ species in terms of proximate compositions, fatty acid, and amino acid profiles. The results revealed that the biochemical composition of hybrid PH×PN was comparable with either one of its parents’ species. The crude lipid and total saturated fatty acids (SFAs) were significantly higher in hybrid PH×PN and P. hypophthalmus. Also, crude protein and docosahexaenoic acid (22:6n-3, DHA) were higher in the hybrid PH×PN and P. nasutus. However, there were no significant differences recorded between the hybrid and its parents for omega-3 (n-3PUFA), total polyunsaturated fatty acids (PUFAs), and eicosapentaenoic acid (C20:5n-3, EPA) and (C22:5n-3, EPA). Likewise, the total essential amino acids (EAAs) was significantly higher in hybrid PH×PN and P. nasutus. In summary, certain components did not deviate much from either of their parents’ species or even enhanced in the hybrid compared to P. nasutus. Therefore, the production of this hybrid could be an alternative to meet the market demand for P. nasutus.
