CHANNEL AND SMALL RIVER BASED IRRIGATION AND FISH-BREEDING COMPLEX Russian patent published in 2018 - IPC A01K61/00 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to the hydraulic engineering and can be used to conduct aquaculture in fish-breeding farms, established at irrigation systems canals. Channel and the small river based irrigation and fish-breeding complex includes a system of interconnected structures in the form of near canal water return multi-sectional fish-farming basin, canal and canal-pond spawning grounds, water intake and water discharge devices, removable mesh partitions, adjustable water and fish passage outlets, rainwater drain pipe with perforated pipes for the water supply to the channel spawning area, water outlet-drain on the channel-pond spawning area, supplying channel for the fry subsequent release to the fish-breeding ponds. Near the canal fish-breeding tank slopes are made with the impervious polymer geosynthetic material and the gravel-pebble material protective coating. Channel spawning area bottom and slopes are made with the gravel-pebble material artificial coating and enhanced roughness elements in the form of concrete cubes, which are the fish spawning substrate. Canal-pond spawning ground bottom is made with the artificial vegetable substrate. Water lines, fish passages and fish passing facilities outlets are equipped with the fish screen and trash nets.

EFFECT: application of the invention will allow to expand the irrigation and drainage systems channels functionality, ensure the most effective and intensive integrated use of their water-resource potential without disturbing the irrigation system water consumption, increase the river aquaculture products production.
