anglais. In a course of the research there was studied the use of microbial drug for water purification in fishery ponds. The research was realized in the Republic of Belarus. As a result of realized research there was shown the possibility of using microbial drug for water quality improvement at commercial fish growing in the ponds and decrease of organic and biogenic contaminations in the waters drained off from the ponds. Use of the drug at concentrations of 4.5 l/ha per season resulted in average during the season to increase the transparency of the water in the ponds as compared with control by 20% (from 40 cm to 48 cm), water content of the reduced mineral phosphorus by 56% (from 0.046 mg P/l to 0.020 mg P/l), the organic pollution of water reduced by 9% (from 23.3 to 21.3 mg O/l) reduced content of suspended substances by 136% (from 51.45 to 21, 18 mg/l). Microbial drug could be used in weakly running water bodies (ponds, reservoirs receivers cage lines and recirculating aquaculture system).
