dc.description.abstractThe study was conducted to determine the possibility of plant oils to substitute fish oil in the diets for Pangasionodon hypophthalmus (Sauvage, 1878) and Pangasius nasutus (Bleeker, 1863) on growth performance, nutrient utilization, body indices and muscle and liver fatty acid composition. The effect of fish oil substitution by crude palm oil in the diets for P. hypophthalmus (Sauvage, 1878) juvenile on lipogenic enzyme activities was also investigated. In the first experiment, four isonitrogenous (300 g kg-1 crude protein), isoenergetic (21 kJ g-1) experimental diets were formulated to contain fish oil (FO), soybean oil (SBO), crude palm oil (CPO) and linseed oil (LO), respectively, as lipid sources each at inclusion level of 120 g kg-1 and fed to triplicate groups of 15 juvenile iridescent shark, P. hypophthalmus (Sauvage, 1878) (mean weight 10.00 ± 0.70 g) and triplicate groups of 10 juvenile P. nasutus (Bleeker, 1863) (mean weight 10.66 ± 0.04 g) to apparent satiation twice daily for 12 weeks. The study has demonstrated the possibility of 100% substitution of FO with vegetable oils such as CPO, SBO and LO in the diet of juvenile P. hypophthalmus and P. nasutus with positive effect on growth, and that crude palm oil and soybean oil are the most suitable vegetable oils as lipid sources in the diet for juvenile P. hypophthalmus and P. nasutus, since better growth performance was recorded in fish maintained on these oil-based diets for 12 weeks. The study also highlighted the requirements for n-3 and n-6 fatty acids series in terms of lower n-3/n-6 ratio, to promote better growth at the juvenile stage of P. hypophthalmus and P. nasutus.en_US
