Abstract
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.
Highlights
To manage modern fisheries, including commercial aquaculture in inland water bodies of Russia, the systematization of various information and the development of a classification or typification of water bodies based on this information is of paramount importance.For each region, based on climatic and hydrological conditions, factors can be identified that limit the use of certain water bodies for aquaculture purposes
If a reservoir was not recommended for aquaculture purposes in terms of hydrological characteristics, as well as territorial location, it was estimated at 0 points according to these criteria
In spite of the fact that practically all the water bodies according to the conditions of moisture supply should be attributed to reservoirs with risky fish farming, the number of not recommended or recommended with significant restrictions water bodies accounted for only 25% of the total. This indicates a high potential for fish farming even in the arid zone of the Rostov region.[19]
Summary
For each region, based on climatic and hydrological conditions, factors can be identified that limit the use of certain water bodies for aquaculture purposes. All these measures will significantly expand the list of potential reservoirs where breeding of certain types of fish or aquaculture animals is promising
