Current status of aquatic biological resources stocks in the reservoirs of the North Caucasus
The data on morphometric and hydrological characteristics of the reservoirs are provided, as well as on their feeding capacity and ichthyofauna composition. Structure of the stocks of the commercial fish species has been assessed, and analysis of actual yield of aquatic bioresources has been conducted. Actual fishing productivity has been analyzed, and the measures have been identified. Efficient commercial exploitation of the water bodies of this type is possible under the condition of ichthyofauna rehabilitation using more valuable fish species with a high growth rate. Fish catches in the multi-purpose water bodies can increase by 7–8 times or more, relative to the current state.
