The survey of possibility of beluga (Huso huso) sturgeon culture in different densities in Khuzestan province
The influence of stocking density was investigated on growth, survival and FCR of great sturgeon (Huso huso) juvenile in north of Khuzestan province (Dezful). The study was conducted by Southern Iran Aquaculture research center. This study was done from September 2013 to July 2014 in three stage wit...

In the first stage density of 1.5, 3 and 6 kg/m^2 during two month was performed. The initial weight and length of fish in this stage considered as 143±0.29 g and 316±1.1 mm. In the second stage 3, 6 and 9 kg/m2 density were introduced. The initial weight and length of fish in this stage considered as 548.58±33.26 g and 416.5±0.81 mm and duration of the stage was 84 days. In the third stage 6, 9 and 12 kg/m^2 density were introduced and initial weight and length were 1571.33±71.33 g and 687.5±10.96 mm. Growth and feeding index were assess in each stage.
