ABSTRACT This study assessed the impact of varying dietary methionine (Met) and digestible energy (DE) levels on the growth performance, feed utilization, and glycemia in hemolymph of juvenile Penaeus vannamei reared under hyperosmotic salinity (43-48 g L−1). A 2 × 3 factorial design was used to evaluate six diets, varying in two DE levels (15.7 and 16.6 MJ kg−1, DM basis), achieved through soybean oil addition, and three Met levels (7.6, 8.5, and 9.9 g kg−1, DM basis), adjusted with […]
