Comprehensive assessment of aquaculture potential of the southern and south-eastern waterbodies in the Rostov region

The paper presents materials on a comprehensive assessment of reservoirs for commercial aquaculture, exemplified by some waterbodies in the Rostov region. We have examined 24 waterbodies located in the southern and south-eastern Rostov region. The assessment of reservoirs was carried out based on hydrological and hydrochemical indicators, the point score of which was carried out in four sets of issues. Almost all the studied water bodies because of the lack of required water supply have been classified as reservoirs with risky fish farming. Most aquaculture reservoirs recommended for commercial farming are found in the zone of a very arid climate, characterized by annual precipitation ratio of 0.33-0.44. A brief hydrochemical description of each investigated waterbody can be used to form scientifically-based recommendations for the organization of commercial fish farms in Russia.
