Effects of Dietary Sodium Acetate on Growth Performance, Fillet Quality, Plasma Biochemistry, and Immune Function of Juvenile Golden Pompano (Trachinotus ovatus)

Six isonitrongenous and isolipidic diets were formulated to feed 360 fish (mean initial body weight: 6.06 ± 0.02 g) with graded levels of sodium acetate (SA1 (0), SA2 (250 mg/kg), SA3 (500 SA4 (1000 SA5 (2000 SA6 (4000 mg/kg)) for 8 weeks. The results revealed that weight gain rate, specific growth intake golden pompano significantly increased in treatments ( id="M2"> p < 0.05 ).
