dc.description.abstractThe effects of diets containing peanut oil at different ratios on growth performance, biochemical and fatty acid compositions of juvenile European seabass, Dicentrarchus labrax, were evaluated under controlled conditions in the recirculated system for 12 weeks. The trial was planned as 6 groups (18 tanks) with three replicates and stocked as 12 fish (mean weight similar to 4.72 +/- 0.01 g) in each tank and was fed by one of six experimental diets. Each diet was formulated to replace 0% (FO, control), 20% (PNO20), 40% (PNO40), 60% (PNO60), 80% (PNO80) and 100% (PNO100) of the fish oil with peanut oil. Feed conversion ratio (FCR) was the best in the PNO80 group (p<0.05). The fatty acid composition of the fillet reflects the fatty acids in the test diets. The polyunsaturated fatty acids (PUFA) of PNO60, PNO80 and PNO100 groups were lower than other experimental groups. The saturated fatty acids (SFA) were the highest in the PNO100 group. Some fatty acids [C16:0, palmitic acid (PA); C20:0, arachidic acid (AA); C18:1n-9c, oleic acid (OA); C20:1, eicosenoic acid (ESA); C20:3n-6, dihomo gamma-linolenic acid (gamma-ALA); C20:5n-3, eicosapentaenoic acid (EPA) and C22:6n-3, docosapentaenoic acid (DHA)] were present higher proportion in fillet of all groups compared to experimental diets. EPA was lower in control and PNO20 compare to experimental diets. As a result, the use of peanut oil in different ratios in the diets had not a negative effect on the growth and proximate composition of European sea bass. This study also indicates that as long as fish meal is available in the diet, peanut oil can be considered a reasonably effective replacement for fish oil in sea bass feeds.
