FISH GROWING SYSTEM AND METHOD OF ITS OPERATION Russian patent published in 2019 - IPC A01K61/00 

FIELD: fishing and fish farming.

SUBSTANCE: complex includes at least one fish-breeding basin, drum filter, biological filter with quartz sand, biofilter with floating bio-loading, oxygenator and pumps. Distributing header is connected with drum filter, biofilters and oxygenator with possibility of water flow along directions: drum filter – collector – biofilter with quartz sand – drum filter, pool – drum filter – collector – oxygenator – pool, pool – drum filter – collector – biofilter with floating bio-loading – pool. Fish-breeding basin, the drum filter, biofilters and oxygenator are arranged at the same level. Fish-breeding basin is connected to the drum filter by the intake pipe located diagonally from the center of the fish-breeding basin to its upper edge through the skimmer located from the inside of the fish-breeding basin, which allows to receive water by two flows from the bottom through the pipe and overflow over the edge of the skimmer. Pipeline receiving water from fish-breeding basin is located on the external side of fish-breeding basin and is located below water level in fish-breeding basin, providing for water supply by gravity into drum filter, accumulating part of which is connected via pumps with distributing collector.

EFFECT: invention improves quality and efficiency of water treatment in a piscicultural system.
