[Effect of stocking density on growth of juvenile Acipenser schrenckii]

The effect of stocking density on growth of juveniles Acipenser schrenckii was studied, and the results showed that juveniles Acipenser schrenckii reared for 28 days in a flowing water system under different stocking densities of 0.232, 0.665, 1.347, and 2.469 kg.m-2 grew in allometry. There were no significant differences between the final and initial SV under the four treatments. The growth efficiency, DWG, NY, and SGR of juveniles were decreased with the increase of stocking densities. However, the FCR and NY were increased with the increase of stocking densities. There were significant differences between these parameters under the low and high densities treatment after 28 days. Moreover, there was a significant negative linear correlation between stocking density (D) and special growth rate (SGR).
