DISTRIBUTION AREA AND STOCKS OF ENTREPRENEURIAL FISH SPECIES IN THE ZHAIYK-CASPIAN BASIN

This article presents an analysis of the pace of fishing in the fishing areas, the dynamics of fishing of semiconductor species of fish for many years.It is shown that the water of the river Zhaik and Kigash and its influence on the number of fishing species in the pre-winter period of migration.It was established that multi-year fishing (2006-2019) as in the river Zhaiyk and in the river Kigash was unstable and fluctuated for many years. The characteristic is given that the volume of the limit allocated for the catch of semi-passable fish on the Zhaiyk river does not exceed 40% and the dynamics of behavior of some fish species remained at the level of the previous year. In the period from 2006 to 2019, indicators of results on the catch of semi-passable fish species on the Zhaiyk river were analyzed. In addition, the volume of the annual flow of the Zhaiyk river and the indicators of the Kigach river for the last decade (2009-2019) According to our study, data on the impact on the stocks of semi-passable and river fish are given. The results of the study showed that over the last 2011 - 2019 years, there was a decrease in the number of semi-pass and pass-through fish.
