For this purpose , fingerlings with initial weight 7.25 + 0.4 g were distributed in 3 treatments with density of 50, 75 and 100 fish per each m3 and cultured for 60 days. The growth factors (BWI, LI, SGR, CF, and FCR) and survival rate were measured. The results showed that with density increase some of the growth factors which contain BWI, LI and SGR were decreased but some others (CF, FCR) were increased ( p<0.05). Also the density of stocking had no effect on survival rates of treatments (p>0.05). In Conclusion, by study on growth factors and survival rate, the best results were observed in lower density (50 fish per each m3). Manuscript profile
