FIELD: agriculture.
SUBSTANCE: device comprises a trap, an aerator and a direct-flow channel. The front part of the channel is communicated with a water reservoir, and the rear one is made as dead-ended. The direct-flow channel is arranged as a reservoir. The bottom and side walls of the channel are made of water-impermeable material, for instance, from polyethylene film. The aerator comprises a L-shaped pipe. The vertical component of the L-shaped pipe is arranged at the outer side of the reservoir. The horizontal component of the L-shaped pipe is communicated with the reservoir by means of a sleeve. In the lower part of the vertical component of the pipe there is a sprayer, which is connected by means of a hose to a cylinder filled with oxygen or a compressor.
EFFECT: design will make it possible to increase efficiency of water reservoirs fishing off, especially in those remote from settlements and electric networks.
