| In the current study the plasma metabolites of silvery-black porgy (Sparidentex hasta) juveniles fed different lipid sources were analyzed in order to bio-monitoring the fish health condition. In this regard, an eight-week feeding trial was conducted using seven isonitrogenous (50%) and isolipidic (20%) experimental diets namely: FO, CO (canola oil), SO (sunflower oil), T (tallow), FC (fish oil + canola oil, 50:50), FS (fish oil + sunflower oil, 50:50) and FT (fish oil + tallow, 50:50). Fish fed with SO diet had the highest liver lipid content. Liver n−9 monounsaturated fatty acids, n−6 and n−3 poly unsaturated fatty acids were highest in fish fed the CO, SO and FO, respectively (P < 0.05). Fish fed FO and T diets had the highest plasma total cholesterol, whereas fish fed CO and SO diets had the highest plasma triglyceride and VLDL levels (P < 0.05). Plasma ALP and ALT were highest in fish fed SO and FO groups, respectively. Fish fed FS diet had the highest plasma TBARS concentration, whereas plasma CAT activity was highest in fish fed FO and FS diets. The results of this study demonstrated that different dietary lipid sources can drastically change fatty acid profile of the liver which consequently can alter different metabolic pathways that can affect plasma metabolite health indices in silvery-black porgy juveniles. | ||
