ABOUT THE RESULTS OF ACCLIMATIZATION OF THE WHITE CU-PID (CTENOPHARYNGODON IDELLA) AND THE WHITE CARP (HYPOPHTHALMICHTHYS MOLITRIX) ON THE KAPSHAGAI RESERVOIR

Abstract

This article presents a generalizing holistic material on the acclimatization of herbivorous fish (white amur and white carp) in the Kapshagai reservoir. The main issues of its discussion are the timing and volumes of the introduction of fish-bearing material of different ages, the periods of naturalization of settlers in the ecological conditions of a new reservoir, the years of the formation of the fishing population and the beginning of their entry into the fishery. Based on the results of many years of research and analysis, information on the catches of acclimatizers is presented starting from the time their catch was recorded in fishing statistics. The economically valuable biological signs characterizing them as valuable objects of fishing in high demand are shown. It also provides information on the distribution area of the reservoir (feeding, spawning migration, wintering) and provides recommendations for the further conservation of these valuable fish species as part of the ichthyofauna of the reservoir. The research is funded by the Ministry of Ecology, Geology and Natural Resources of the Republic of Kazakhstan (Grant no. BR10264205).
