COMPLEX OF STRUCTURES FOR FISH GROWING AND FISHING IN LAKES Russian patent published in 2010 - IPC A01K99/00 

FIELD: agriculture.

SUBSTANCE: complex comprises a satellite water reservoir with adjoining coastal shallow zone, main and at least one additional aerators-flow developers. Satellite water reservoir is connected to lake by water-intake and water-collection coastal channels. Coastal shallow zone of satellite water reservoir for lakes with sloping coasts is equipped with a fill dam. Fill dam is made of soil excavated in process of water reservoir and coastal channels erection and is arranged at the section between water-intake and water-collection coastal channels. On both sides of dam there are deep underwater channels arranged with the help of suction dredge. To create sections of water reservoir with highest content of oxygen for fishing, aerators-flow developers are installed in coastal channels. For lakes with wide coastal strip of aqueous plants and intensely overgrown with aqueous plants, coastal shallow zone of satellite water reservoir is equipped with dam or deep-water section and swath. Dam is made and arranged in the manner similar to dam with lakes with sloping coasts. Deep-water section is arranged with area of at least 0.5-1.0 ha and is produced by suction dredge. To create sections of water reservoir with highest content of oxygen for fishing, aerators-flow developers are installed in coastal channels and swath.

EFFECT: design makes it possible to provide for the possibility to grow commercial fish with application of satellite water reservoirs in lakes with sloping coats, lakes, shallow coastal zone or water area of which is intensely overgrown with aqueous plants, and also to increase efficiency of such water reservoirs usage.
