METHOD FOR INCREASING OPERATIONAL EFFICIENCY OF FISH-REARING PONDS Russian patent published in 2007 - IPC A01G31/00 A01G31/02 

FIELD: pond fishery and plant growing, in particular, process used in complex ponds with different forms of property.

SUBSTANCE: method involves joint growing of fishes and plants in pond; growing plants on bed floating in pond, said bed being filled with porous, granulated, chemically neutral artificial substrate and positioned above pond water surface so as to provide self-penetration of water through capillaries of substrate granules to bed surface without filling cavities between substrate granules by adjusting position of bed with the use of lifting force provided by means of floats mounted under bed. Floating bed consists of container having netted bottom and filled with porous, chemically neutral, granulated substrate, and floats equipped with upper air feeding opening and lower water feeding opening for adjusting lifting force developed by floats and extent of flooding of substrate within container.

EFFECT: increased yield of fish and plant products from unit of area.
