Artificial propagation method of five-color fancy carps

Abstract

The invention relates to an artificial propagation method of five-color fancy carps. The method comprises the following steps of (1) preparation of a parent fish pond; (2) parent fish selection; (3) parent fish breeding; (4) artificial propagation; (5) roe nest arrangement; (6) artificial incubation; (7) early-period breeding; (8) primary optimization and later-period breeding; and (9) secondary optimization and later-period intensive culture. The artificial propagation method of the five-color fancy carps has the advantages that artificial reproduction estrus-promoting drugs are used to promote parent fishes to realize centralized oestrus and spawning fertilization; centralized hatching is performed; the five-color fancy carps with excellent individual strains are bred; the muscle is full; the color is bright; the body form is symmetrical and attractive; and the variety characteristics are obvious.

Description

technical field [0001] The invention relates to the technical field of koi breeding, in particular to an artificial breeding method for five-color koi. Background technique [0002] Five-color koi is produced by mating light yellow and three-color koi. It is named five-color because of the white, red, black and blue indigo on its body. When it is white and five-color, the beautiful type with scarlet plate is the best. The five-color koi changes a lot before it is 2 years old, so it is necessary to observe the texture and texture in detail when it is 1 year old. When it is 3-4 years old, it will be clear how its quality is. The five-color koi has excellent ornamental value, but it must pass strict It is difficult to obtain the five-color koi with stable and outstanding characters by existing breeding and breeding techniques. Contents of the invention [0003] The present invention provides a kind of artificial reproduction method that can obtain the five-color koi of stabl...
