Friends who raise dollfish, see how to design the dollfish breeding base.

According to the unique ecological habits of baby fish, the living habits and ecological environment suitable for the growth and development of baby fish should be fully considered in the design of culture pond.

Pool wall requirements 1, cut off water, so that it does not leak. 2. Safe and firm, able to withstand the pressure of the pool wall for four weeks and the pressure in the pool water, and the pool wall does not sink. 3. Anti-escape facilities should be provided. Doll fish culture pond wall is generally made of square stone, brick or concrete, cement caulking, the pool wall should be smooth with cement paste or paste ceramic tile, the top of the pool wall should extend 10 centimeters into him to prevent the baby fish from escaping.

The bottom structure of the doll pond is generally compacted with stones, with a thickness of 20cm to 30cm, then filled with small stone slag, and finally paved with concrete. In order to facilitate drainage, the bottom of the pool is tilted from all around to the center, with an inclination of about 2%, and then from the center to the outlet at one corner, with an inclination of about 1% to 1.5%.

The position of the inlet is based on the intake channel and opposite to the outlet is located at the corner of the pool. The water inlet should be higher than the pool wall, preferably 60 cm higher than the surface of the ground, and extend 20 cm into the pool. The water inlet material can be made of cement pipe or concrete, cast iron pipe and plastic pipe, no matter what material is used in the water inlet. Control facilities and filters must be installed. The control facility adopts a straight-through globe valve, and the size of the pipe diameter can be determined according to the amount of water needed at the mouth of all kinds of doll fish pond and the inlet pressure.

The larval pool can choose 100-300mm, and the adult pool can choose 300mm-500mm. The intake filter material should be made of stainless steel, and the same item should be determined according to the size of the doll fish pond.
