Recommendations on the state of the sturgeon population of the irtysh river and its optimal extraction from the natural environment for reproduction
The results of studying the current state of the Siberian sturgeon population, clarifying the range of its distribution, the number and size-age groups in various sections of the Irtysh River are presented. Preliminary recommendations are given on the possibility of obtaining a small part of the population for the purpose of artificial reproduction. Ecological monitoring was carried out by the route-expedition method, by examining the Yertis River and the estuary areas of large flowing tributaries and reservoirs for the presence and distribution area of rare fish species. The work uses materials of research reports on the program 037 "State accounting and cadastre of fish resources" for 2004-14, data from the archives of Kazniirh LLP.When conducting research, we were guided by the provisions of Normative and methodological documentation. The research is funded by the Ministry of Ecology, Geology and Natural Resources of the Republic of Kazakhstan (Grant no. BR10264205)
