FIELD: fishery and sewage water cleaning. SUBSTANCE: method involves introducing adapted algologic complex containing diatomic green and Protococcaceae algae into algae ponds at contact mode of operation; directing sewage water through algae ponds; cleaning sewage in crayfish ponds which had been previously inoculated with Daphniamagna culture; using sewage water, upon 30-40 days of biological cleaning, for young fish rearing; simultaneously stocking ponds with carp larvae of three day age, with stock density of 30,000-40,000 species per hectare, or with golden carp with stock density of 30,000 species per hectare, and with phytovirous fish with stock density of 10,000 species per hectare; directing sewage water through botanic platform planted with higher aquatic plants and positioned between crayfish ponds and fish-rearing ponds. EFFECT: increased efficiency in cleaning sewage water, reduced cost for sewage cleaning and fish feeding. 2 cl, 1 dwg, 3 tbl
