Description In this study, we optimized the dietary methionine requirement of juvenile silver pompano
(average initial weight of 5.47 g). Six isonitrogenous and isolipidic diets (420 g/kg crude protein
[CP] and 60 g/kg lipid) were formulated with different concentrations of methionine (5.1, 6.9,
9.0, 10.7, 13.1, and 15.2 g/kg dry diet) and a constant level of cysteine (5.3 g/kg). Fishes were
randomly stocked in a recirculatory system for a feeding trial of 90 days. After the feeding trial,
significant differences (P0.05) were observed among hepatosomatic index, viscerosomatic
index, muscle ratio, condition factor, serum glucose, triglycerides, and erythrocyte
count. The optimization of the fitted quadratic regression for WG, SGR, TGC, FCR, and PER based
on the dietary methionine level showed that the optimum methionine requirement of silver
pompano in nursery phase ranged from 11.6–11.8 g/kg dry diet (27.6–28.1 g/kg dietary CP),
corresponding to a dietary cysteine level of 5.3 g/kg.
