This study was conducted to investigate the effects of different dietary lipid sources on the growth, survival, body composition and tissue fatty acid profile of juvenile olive flounder, Paralichthys olivaceus. An 8-week feeding trial was conducted to evaluate the efficiency of five dietary lipid sources in diets for olive flounder juveniles. Six isonitrogenous and isocaloric practical diets were formulated to contain different lipid sources, including soybean oil (SO), fish oil (FO), eicosapentaenoic acid triglyceride (EPATG) and ethyl ester (EPAEE) forms, docosahexaenoic acid triglycerides (DHATG) and a 1:1 blend of soybean oil and DHATG. Triplicate groups of fish (6.8±0.01 g) were fed one of the experimental diets to apparent satiation twice daily for 8 weeks. The vest growth performance was recorded in fish fed the DHATG diet which was significantly higher than all the other treatments. Similarly, fish fed the DHATG diet had the highest protein efficiency ratio and feed efficiency values which were significantly higher than those fed the SO and EPAEE diets. Whole body proximate composition and somatic parameters were not influenced by the dietary treatments. Muscle of fish fed with SO and FO diets were rich in 18:1n-9, 18:2n-6 and 18:3n-3, whereas those of fish fed with EPATG, EPAEE and DHATG diets were rich in n-3 polyunsaturated fatty acids (HUFA). These findings indicated that the inclusion of n-3HUFA oils in olive flounder feed could be beneficial for the fish while simultaneously increasing the concentration of beneficial n-3HUFA in fish fillets destined for the human consumer.
