MAIN PERIODS OF FISHING PROHIBITING IN THE VOLGA RIVER DELTA AND THEIR BIOLOGICAL SENSE

The article presents an analysis of the Fisheries Rules for the Volga-Caspian 
fishery subarea (Astrakhan region) in terms of establishing time limits for the 
catch of living resources. The dynamics of the limits duration, the timing of its 
beginning and end in different versions of the Fisheries Rules for 150 years is 
shown. It was revealed, that in the modern Fisheries Rules the timing of fishing 
for living resources is set in accordance with the features of their life cycle in 
the lower Volga, ensuring the preservation and growth of the basin’s stock. 
Biological inexpediency of further prohibition periods shortening is noted.
