Migratsii ryb v Zaregulirovannykh Rekakh analyses and generalizes large amount of material on biological and hydraulic measures facilitating migrations of fish in rivers of Russia under conditions of regulated flow and flow withdrawal. Main biological, physical and engineering aspects of this complex problem are considered including spawning and downstream migrations of fish, managing their behaviour in water flow; development and application of various fish passing and diversion devices; specific strategies for protection of migratory and resident fish species. General patterns of fish migrations are presented along with basic mechanisms of their migration behaviour (rheoreaction, orientation in the water f;ow, locomotor characteristics, behaviour in rheogradient and in a heterogeneous flow: turbulence, hydrostatic pressure, water temperature, etc.).
Patterns of fish behaviour as they move through dams and in proximity of water intake devices are considered. Downstream migrations and entrainment of juvenile fish in water intakes are considered in detail, analysing the factors affecting these processes, main causes of juvenile fish injury and death during their downstream migration through turbines of hydroelectric power stations. Principles of fish protection, various methods and measures preventing the entrainment of fish in water intakes as well as main principles and strategies for protection of fish populations are discussed. Speci?c measures and tactics for fish protection under conditions of regulated and withdrawn flow are also considered.
Migratsii ryb v Zaregulirovannykh Rekakh will be interesting for ichthyologists, hydrobiologists, ecologists, fishery specialists, biodiversity managers, biology and engineering students.
