Abstract

The invention discloses a koi fish artificial breeding method, and relates to the technical field of aquaculture. The method comprises the following steps: building an infrastructure mainly comprisinga cement pond which comprises a breeding pond and a raising pond, a water circulation treatment system which comprises a pipe drawing chamber, a sedimentation chamber, a physical chamber, a biochemical chamber and a clear water sterilization chamber, and an earth pond; carrying out artificial breeding by sequentially carrying out broodstock selection, broodstock raising, spawning, fertilization and hatching; carrying out fish breed raising and selection to keep koi fish with good shapes, bright colors, well-proportioned patterns and elegant swimming postures; carrying out adult fish raising and wintering during a wintering stage from the end of October to the middle of next April, wherein koi fish is transferred to the cement pond for wintering, and feeding is stopped when the temperatureof water is lower than 16 DEG C; transferring fries to the earth pond after wintering; controlling diseases with manners such as disinfecting the cement pond and the earth pond; and catching and transporting the koi fish. With the breeding method provided by the invention, the raised adult koi fish are cream of the crop. The koi fish inherit the features of the original broodstock, and are classic and pure. The koi fish provide great ornamental value and good economic benefit.
