FIELD: agriculture.
SUBSTANCE: device comprises a trap and a sprayer to increase efficiency of fishing. The trap consists of a rigid frame, covered with a water impermeable material, for instance, with a polyethylene film. The frame forms a tray, where a trap is installed, being open or closed on top. The sprayer is placed into the vertical component of L - shaped pipe. The vertical component of the L-shaped pipe is arranged at the outer side of the tray, in which the vertical water flow is developed under action of floating bubbles. The horizontal component of the pipe is installed inside the tray. The horizontal component of the pipe creates a surface flow of oxygen-saturated water directed along the tray walls and at the outlet from it, making a rotary motion in the tray.
EFFECT: increased efficiency of fishing.
