Abstract

Aims In this research, we investigated the effects of Stocking Density on Growth performance and survival rate of Persian Sturgeon and Beluga. Materials and Methods Stocking densities for treatments 1-5 of Persian Sturgeon in stages 1 were 6, 8, 10, 12 and 14 fish/l (initial weight: 116mg) and in stage 2 were 1, 2, 3, 4 and 5 fish/l (initial weight: 2218/6mg). Stocking densities of five months old Beluga juveniles (initial weight: 109. 95g) for treatments 1-5 were 80, 100, 120, 140 and 160 fish/m3 in each 250-liter tank respectively. Findings Growth and Feeding parameters were affected as the stocking densities increased in both species. In stage 1 in terms of weight, SGR and food efficiency, treatments 1 and 2 showed significantly higher values (p<0. 05) comparing with treatment 5, treatments 4 and 5 and all treatments respectively. In stage 2, there are significant differences amongst the all treatments in terms of weight and SGR except treatments 3 and 4. Food efficiency in treatment 1 was significantly higher (p<0. 05) than the rests except treatment 2. In Beluga, there were significant differences amongst all treatments except treatments 3 and 4 in terms of weight, SGR, and food efficiency and the highest values were observed in treatment 1. Conclusion The best stocking densities for stage 1 and 2 of Persian Sturgeon were 8-10 and 1-2 fish/l respectively and for Beluga, juveniles were 80-100 fish/m3.
