Abstract

Ichthyological observations data on the dynamics of fry fish migrations in flow conditions of industrial water supply systems of thermal power plants are presented. The basic factors controlling the process of migration and redistribution of fish in turbulized flows are discussed. The method is proposed for the control of fish movement trajectories in inlet chambers of water intakes of module pumping stations as well as an engineering solution to the problem of collection and diversion of alive fish from the water intake-affected zone. The biological efficiencies achieved with introducing the fish protection technology offered are given for various species.
