Effect of stocking density on growth of juvenile Acipenser schrenckii

Abstract

Abstract: 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穖^-2 grew in allometry. There were no significant differences between the final and initial SVunder the four treatments. The growth efficiency,DWG,NY, and SGR of juveniles were decreased with the increase of stocking densities. However, the FCRand NYwere 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).

Key words: Acipenser schrenckii, Specific growth rate, Growth efficiency, Feed conversion rate, Aquaculture, drought tolerance, physiological response., growth index, watermelon, genotype
