FIELD: agriculture.
SUBSTANCE: invention relates to fish farming and can be used in enterprises engaged in artificial reproduction of fish stocks. A device for incubating eggs of pasted fish species comprises a tank (1) with running water, a spawning nest-substrate of mesh tape, a turbine (7) for a uniform supply of water to the surface of the spawning nest. The mesh tape is folded into a spiral (3) and is provided with protrusions on the edges along the entire length. The spiral (3) on the end sides is fixed with clamping rings (6). The mesh tape on one end is equipped with the axis (4) of rotation. The turbine is rigidly fixed to the axis (4) of rotation. The ends of the axis (4) are pivotally mounted into the deepenings of two transverse beams (8), mounted in the slots. The slots are made in the opposite walls of the tank (1).
EFFECT: significant increase in eggs laid on incubation with a decrease in water consumption.
