Bacillus subtilis feeding device for aquaculture

The utility model discloses an aquaculture bacillus subtilis putting device which comprises a power ship body, a fan-shaped putting component for putting bacillus subtilis after being mixed is arranged on the rear side of the end portion of the power ship body, and the bacillus subtilis enters a plurality of putting branch pipes arranged in a fan shape in a high-pressure mode through a putting main pipe. The bacillus subtilis gathers and enters the interior of the cavity, the bacillus subtilis can be sprayed to a water area at the rear end of the driving direction of the power ship body through the flat fan-shaped feeding ports which are arranged at equal intervals in a high-pressure fan-shaped manner, and the bacillus subtilis which is fed in a fan-shaped manner can cover a relatively large water area; and meanwhile, the put bacillus subtilis can be well mixed with water when the water in the water area where the power ship body travels is in a movable state, so that the bacillus subtilis putting efficiency
