Fish Protection, In Relation To The Hydraulic Structures Of The Moscow Canal

The purpose of the research is to establish functional characteristics for Ivankovsky water intake, hydrological features hydroelectric power station area, biological parameters representative fish and develop recommendations protection retrofitting this object, with a non-capital nature. surveys were determined by terms reference contract, species ichthyofauna in area object. Ichthyological samples (control catches) made according scheme: 2 double catches at object: 1st-in intake zone; 2nd - on border sanitary zone upper stream, period May-August. Dominant number rest were: tyulka (Freshwater tyulka) 82% column bream (Abramis brama) almost 90% bottom, followed gustera (Blicca bjoerkna) pelagial bottom (7-10%). Because this, RZS designed facility should mainly meet conservation Freshwater brama). It recommended use complex reds "input-action-output" scheme additional environmental behavioral methods: air-bubble curtains or electric barriers-focused fry up 20-30 mm, when combined mechanical larger fish.
