If working ejecting stream is preliminarily saturated with atmospheric air, its outer borders are saturated with air in form of finest microbubbles which form boundary layer ("air cushion") at contact with which young fish do not suffer from discomfort and easily take up hydrodynamic pressure built in mixing chamber. Moreover, provision of boundary layer saturated with microbubbles of air makes it possible to considerably reduce value of friction coupling of two streams, main getting from working nozzle and ejecting, containing young fish.

EFFECT: provision of good conditions for letting out young fish into fish outlet, reduced damage of young fish.
