CRAYFISH IN THE RESERVOIRS IN ROSTOV REGION: STATE OF POPULATIONS, FORECAST AND MANAGEMENT OF ITS STOCKS IN CURRENT PERIOD

Abstract

Astacological research in AzNIIIRKh is carried out with the aim of studying the natural populations of river crayfish living in the reservoirs of the Rostov region, assessing their stocks, developing a total allowable catch and measures on rational use of the stocks. The work summarizes the results of AzNIIIRKH’s long-term research on the biology and ecology of the Kuban crayfish populations in the waterbodies of the Azov Sea basin. The crayfish habitat in fishery reservoirs of the Rostov Region has been characterized. The qualitative and quantitative characteristics of the productive crayfish populations and the factors hindering the propagation and development of populations of crayfish are considered. The author’s approach is given to the forecasting of total allowable catch in Rostov region. Recommendations for the conservation and rational use of crayfish-productive populations have been developed.
