Abstract: The experiment was conducted to determine the effects of stocking densities (12.04, 24.08, 48.16, 144.49, 240.81, 337.13, 433.46, 529.78, 626.11 individuals×m-2) on survival, growth and energy budget of juvenile L. vannamei with the initial wet body weight of 0.026±0.006g. The experiment lasted for 45 days. The results showed that I. The survival for densities of 12.04, 24.08 and 48.16 individuals×m-2 were significantly higher than for density of 626.11 individuals×m-2, but were not significantly different from other treatments. II. The specific growth rate for densities of 12.04 and 24.08 individuals×m-2 were significantly higher as compared with other treatments; the relationship between specific growth rate (SGRd) and density (D) was described by the following regression equation: SGRd=-0.3911Ln(D)+10.068 (R2=0.8745).
