ABSTRACT

Various dietary fats were used to assess their impact on the fatty acid profile of snakehead murrel, saul (Channa striatus). The saul grow-out (av. wt. 27.36 ± 0.09 to 32.54 ± 0.41 g) were fed for 12-weeks with seven experimental diets (F1, F2, F3, F4, F5, F6 and a control, F7 of natural foodstuffs, NATFO). F1 (L3HUF) contains 0.5% n-3 fatty acid & 7.5 % saturated oil; F2 (H3HUF) contains 1.0% n-3 fatty acid & 7.0% saturated oil; F3 (MUSOL) contains 8.0% mustard oil; F4 (LINOL) contains 8.0% linseed oil; F5 (MIXOL) contains 4.0% mustard oil and 4.0 % linseed oil; F6 (SATOL) contains 8.0 % saturated oil. The muscle polyunsaturated fatty acids (PUFA) contents varied with different dietary lipids level which impacted on deposition of fatty acid in flesh. The muscle unsaturated fatty acids, including Docosahexaenoic acid (22:6n3, DHA) and Eicosapentanoic Acid {C20:5n-3, EPA), levels, were comparatively higher in MIXOL diet followed by H3HUF than in the other diets, indicating selective deposition of various fatty acids in each feeding trial. It was concluded that dietary fats in the diet has role in the carcass composition of fatty acid profile in Channa striatus and the MIXOL (contains mustard oil and linseed oil: 1:1 w/w) could be safely used for better deposition of beneficial healthy fatty acids like EPA and DHA. The addition of mustard oil and linseed oil in the diet are comparative better if we look towards economizing the cost of the brood-stock feed in comparison to the addition of pure fatty acids in the fish diets.
