Problems solved by technology

Therefore, the color change of juvenile parrot fish is the key to the life of parrot fish. Today's farming generally provides a suitable environment for parrot fish and then allows parrot fish to fade and grow by itself. When they grow up, parrot fish that are not suitable for viewing are eliminated. Increased farming costs

Embodiment 1

[0017] A kind of melanization method of juvenile parrot fish, its specific breeding steps are:

[0018] (1) First, carry out ultraviolet disinfection on the fish pond to ensure the cleanliness of the aquaculture water, and then set up multiple oxygen-generating equipment in the aquaculture pond;

[0019] (2) Then put the fish fry in the breeding pond, and irradiate the breeding pond with Co-γ rays when stocking. Since the gamma rays can cause gene mutations, irradiating the fry in the fish pond can induce rapid melanization of the fry, and at the same time will increase the effective Additive feed should be fed. The initial additive should occupy a very small amount, accounting for 1.4%. When the melanin in juvenile fish gradually fades, the proportion of additives should be gradually increased in the feed to ensure the melanization of juvenile fish. Complete and enrich;

[0020] (3) During irradiation treatment, different irradiation doses lead to different fading speeds of ...

Abstract

The invention provides a black fading method of amphilophus juvenile fish, and a black fading feed additive. The black fading method comprises following steps: firstly, a fishpond is subjected to ultraviolet light sterilization so as to ensure that aquaculture water is clean, and a plurality of oxygen generating plants are arranged in the fishpond; Co-gamma ray irradiation is carried out so as to increase juvenile fish black fading speed, and at the same time, the black fading feed additive is added into feed. The black fading feed additive is capable of realizing black fading and red increasing. According to the black fading method, Co-gamma ray irradiation and adding of the black fading feed additive are applied at the same time, so that black fading speed of amphilophus juvenile fish is increased, complete black fading is realized, black fading success rate is increased, and aquaculture cost is reduced.

Description

technical field [0001] The invention relates to the field of parrot fish breeding, in particular to a method for melanizing juvenile parrot fish and a melanizing feed additive. Background technique [0002] Because of its beautiful color, parrot fish is very popular among breeders and has become a kind of ornamental fish. However, parrot fish is not born with beautiful colors. During the growth cycle of parrot fish, there will be no parrot fish after hatching from eggs. The characteristics of the fish, and the fish body has black spots and stripes. After feeding, the appearance of the small parrot fish will gradually change. The muscles of the head and back will gradually bulge, and the thickness will also increase. The body color will also change from stripes or spots to black. Slowly fade to white, and it usually takes at least 5 months, and then continue to feed, the parrot fish will show a light red body color. Therefore, the color change of juvenile parrot fish is the ...
