THE DEFINITION OF FISH PRODUCTIVITY IN LAKES OF WESTERN SIBERIAN TAIGA ACCORDING COMPLEX OF ECOLOGICAL INDICATORS
The dependence of commercial fish productivity in lakes of western Siberia taiga zone (Tyumen region) from a number of factors was installed according method of multiple regression. Were used the following parameters: the area of the lakes, morphoedaphic index, overgrowing of plant, the biomass of zooplankton and zoobenthos The resulting regression equation can be used to estimate the potential fish productivity of fishery water bodies (lakes) in limits of the minimum and maximum values of the ecological parameters. Should be take into account the regional nature of the obtained dependencies, and therefore the observations on water bodies are necessary in order to identifying the key factors that characterize the ecological situation. Method may find application in forecasting the magnitude of possible catch and planning of fish culture.
