Creation of effective and easy-to-replicate in laboratory conditions culture medium for isolation of salmonella out of water, which could make it possible to increase the safety, authenticity and efficiency of bacteriological study of aquatic medium objects, was realized in the conditions of the Republic of Belarus. In course of the numorous preliminary experiments there was developed an enrichment medium containing the following: nutrient yeast (5 g/l); potassium phosphate monosubstituted (8,6 g/l); sodium hydrate (1,4 g/l); 0,1% brilliant green solution (5 cm3/l); 0,01% solution of crystal violet (10 cm3/l); distilled water (1 l). The analyzed medium was estimated in accordance with the following propertiesd: medium sensitivity; efficiency; inhibition of bacteria growing. Research result showed that the experimental medium was more sensitive in comparison with the selenite one. Studying of the efficiency of the compared media showed that accumulation of test strains of S. enteritidis on the experimental medium was in 10E4 times higher, S. typhi – in 10E3; S. typhiniurium, S. anatum was in 10 times higher than at selenite media. The experimental studies proved that the experimental culture medium for salmonella isolation out of city water and surface water was more sensitive and easier to use than the selenite medium

In the article concept and essence of aquaponic systems for production of ecologically clean agricultural production without waste technologies is set forth. A degree of a level of studies of the given рroblem in the countries of the Europe, America, Australia and other countries is set forth too. The expediency of application of similar systems for fuller use of power resources of plants for production of heat of the electric power, an opportunity of production of agricultural production in urban conditions and on the limited ground areas is proved
