CURRENT STATE OF COMMERCIAL FISHING ON THE ZHAIYK RIVER

This article analyses the materials of the modern state of fishing for semi-passable fish in fishing areas of the Zhaiyk River. A brief description of the hydrological regime of the Zhaiyk River and its influence on fishing is presented The volume of water runoff has been identified as the most important hydrological determinants of the productivity of fishing fish. It was revealed that the regulation of river flow in the upper part of the Zhaiyk river basin and significant water intake for various needs are the main reasons for the decrease in annual flow volumes in the lower reaches. The hydrological regime of the river. Zhayyk is characterized by significant variability in the volume of annual runoff. In recent years, the river Zhaiyk is a low-water river and its influence has recently been strengthened on the state of bioresources of the river Zhaiyk. It is known that despite the decrease in the water level of the river. Zhaiyk and the deterioration of the environmental situation, fishing for semi-passable fish species continues on stationary tone sites. It has been shown that at present the basis of the fishery is semi-passable and river fish, the reproduction of which is associated with the regime of spring flood. It was revealed that the spawning conditions of fish are associated with the water level in the river, the onset of spawning water temperature and the duration of the flood.
