Contrasts in unsaturated fat creation of egg containers from broodstockspotted babylon, Babylonia areolata, took care of a neighborhood refuse fish and figured eating routine under incubation facility conditions



This study was the first attempt to condition broodstock Babylonia areolatausing the formulated diets under hatchery conditions. Samples of spotted babylon egg capsules from broodstock, which had been fed either a formulated diet or a local trash fish, carangid fish (Seleroides leptolepis) for 120 days were analyzed for proximate composition and fatty acid composition. The formulated diet contained significantly higher levels of arachinodic acid (ARA) (20:4n-6), eicosapentaenoic acid (EPA) (20:5n-3) and docosahexaenoic acid (DHA) (22:6n-3) than those of the local trash fish. The formulated diet also had significantly higher ratios of DHA/EPA and (n-3)/(n-6) polyunsaturated fatty acids (PUFA) than those of the local trash fish but not for ARA/EPA ratio. The fatty acid compositions of egg capsules produced from broodstock fed formulated diet contained significantly more ARA, EPA and DHA compared to the broodstock fed the local trash fish. The ARA/EPA and DHA/EPA ratios in egg capsules were significantly higher in the trash fishfed group compared to those fed the formulated diet. However, (n 3)/(n 6) PUFA ratios in egg capsules produced from broodstock fed the formulated diet did not significantly differ compared to those from broodstock fed the local trash fish. The relatively low DHA/EPA, ARA/EPA and (n 3)/(n 6) ratios in the egg capsules produced from theformulated diet fed broodstock of B. areolatasuggested that this diet was inferior, when compared to the traditional food of trash fish.
