The Features of the Formation of Ichthyofauna of the Sub-Polar Khantay Water Reservoir
V. I. ROMANOV, O. G. KARMANOVA
Abstract
Changes in the species composition and the dynamics of the population of main fish in the Khantay water reservoir are considered. It is shown that fish of prey (pike, burbot, perch) formed the basis of the entire period of the organized fishery. At present, the water reservoir has changed from the white-fish and pike type to the white-fish, perch and carp water reservoir. Within the time of its existence, a substantial decrease in the number of linear mass characteristics, prolificacy of one-age fish and an increase in the time of pubescence are observed. This is to the utmost true for the white-fish (Siberian whitefish, peled, whitefish-pyzhyan) which are represented here exclusively by the indigenous species.
