Title

Effect of stocking density and feeding rate on growth, hematological parameters and water quality in rearing of juvenile Bluga (Huso huso)

Pages

  115-128

Abstract

 growth, hematological parameters and water quality for great sturgeon (Huso huso), were determined at three different stocking densities and three feeding rates. stocking density were 1, 1. 5 and 2 kg m-2 and feeding rates were 1, 2, and 3% body weight day-1. Sturgeon were offered to 18 tanks and 3×3 experimental design was used with two replicates per treatment. Initial average body weights of the fish were 25 ± 1. 5g and were hand-fed a pelleted commercial feed (44 % protein, 20% fat, and 7% ash) twice daily throughout the experiment period. After about 7 weeks of feeding, optimal feeding rate and growth performance was observed in 1 kg m-2 and 3% of body weight day-1 and there were significant difference interaction in stocking density and feeding rate between treatments (P<0. 05). The results demonstrated that hematological parameters were not significantly different in all groups (P>0. 05). No mortality was abserved during the experiment. water quality including ammonia (NH3) and dissolved oxygen (DO) showed significant differences (P<0. 05) among the treatments affected by different densites and feeding rates, while temperature and pH showed no significant difference (P>0. 05). Results show that the optimum feeding rate and stocking density for fishes weighing 25 to 155 would appear at a feeding rate at 3% body weight day-1 with the stocking density 1 kg m-2.
