Cultivation system and cultivation method for fish monomers

The invention discloses a cultivation system and a cultivation method for fish monomers. The cultivation system comprises a plurality of layers of support frames, each layer of support frame is divided into a plurality of mounting units, and a mounting frame capable of overturning at 90 degrees is hung in each mounting unit; a cultivation unit is fixed in the corresponding mounting frame, and a conveyor belt is arranged below one side of the mounting frame at the bottom of each mounting unit; each cultivation unit comprises a transparent box body, a drain outlet and two independent spacers, wherein the inner space of the box body is divided into two independent spaces of different sizes by a first baffle, the bottom end of the second baffle is provided with a diversion plate with a downward gradient, so that water in the large space can flow into a space formed by the first baffle and the second baffle from a gap formed between the top of the diversion plate and the bottom of the tank body, and then flows into a small space from the top of the first baffle, and finally drains out of the box body through the drainage outlet. According to the cultivation system and the cultivation method provided by the invention, by adopting a cultivation method of breeding 1 fish in each cultivation unit, the disease propagation can be reduced, the labor cost can be reduced, the cultivation space can be saved, and the cultivation water can be recycled.
