Topic: Fatty Acid Profile Of Visceral Oil Of Clarias Gariepinus (Burchell, 1822), Heterobranchus Longifilis (Valenciennes, 1840) And Their Hybrid

Description:

Fatty acid profile of visceral oil of Clarias gariepinus, Heterobranchus longifilis and their Hybrid were examined. The oils were extracted using soxhlet extraction method, characterized for physico-chemical properties and part of it analysed for fatty acid profile. The result of the characterization showed that the physico-chemical composition of the visceral oil of the three species of fish differ significantly (p<0.5) from one another. The oil of Heterobranchus  longifilis  was significantly higher than Clarias gariepinus and their hybrid in moisture content, iodine value and melting point. Significant variation also occured in the acid value, peroxide value and saponification value, with Clarias gariepinus having the highest mean value. The oil colour was light yellow for all the species and their refractive index varied, but showed no significant differences (p>0.5). A total of eight different fatty acids were identified from the three species. Saturated fatty acids (SFAs) had the highest percentage. followed by mono unsaturated fatty acids (MUFA) while the least was poly unsaturated fatty acids (PUFA). This finding revealed that visceral oil of most widely farmed freshwater catfish species in Nigeria (C gariepinus, H longifilis and their Hybrid) varied significantly both in physicochemical properties and fatty acids contents. Moreover, the visceral oil of all the species are valuable industrially for soap  making due to high saponification value and also a source of good nutrition should the fish oil industry choose to provide edible catfish oil from processed waste.
