Description
Summary:This experiment was conducted to explore the influences of dietary supplementation with an acidifier blend (AB, contains citric, lactic, and phosphoric acids) on growth, digestive enzymes, and blood chemistry of juvenile Japanese sea-bass, Lateolabrax japonicus . A basal diet was used as a control that contains about 48% protein and 8.6% lipid. Five other diets were supplemented with different levels of AB (0, 1, 2, 3, 4, and 5 g/kg). Each diet was assigned to triplicate groups of fish in 200l experimental tanks, and each tank was stocked with 20 fish (initial weight (27.09±0.08) g). The rearing process lasted for 28 days. After rearing process, total number and average body weight of fish in each tank were measured, and 6 fish per tank were sampled. The results showed diets supplementation with 2 and 4 g/kg AB enhanced weight gain (WG) (from 106.82 to 125.40% and 124.80%) and specific growth rate (SGR) (from 2.59 to 2.90 and 2.89%/day) of fish ( P
