Treatment 1, polyculture plus 150 B. sharpeyi. In both treatment organic and inorganic fertilizer were used the same. In treatments (1), fingerling benni were stock culture system, only artificial food amount of consuming was higher compare to control treatment. According to physical and chemical paramaters the ponds water were suitable. Survival rate in control treatments 95 percent and treatment (1) 93 percent was calculated by using variance analyze test of mean camper were indicated that between production amount of fish in two treatment was not significant difference (P≤0.05( Average of production in 2 treatments was 4976.5±592.74,5993.2±764.04 kg/ha respectively. While treatment 1 had more production compare than control treatment. Advantage of 1 kg fish, advantage in hectare and expenses of 1 hectare was observed significant difference between No 1 treatment and control treatment.
