Embodiment 1

[0022] A method for breeding and cultivating egg breeding goldfish is characterized in that the steps are as follows:

[0023] (1) Breeding pool treatment: 6 days before the breeding, the pool was disinfected with quicklime;

[0024] (2) Pool water treatment: Purify the pool water with a water quality regulator to remove chlorine, ammonia and iron in the water, and make the pH value of the pool water reach 7.6, and the pool water temperature is 24°C;

[0025] (3) Select broodstock: put the egg broodstock in the pond, culture for 14 days, the body length of the broodstock is 10cm, and the ratio of male to female of the broodstock is 2:1;

[0026] (4) Matching male and female broodstock:

[0027] Separate the selected broodstock according to male and female, and put them in two ponds for breeding, with a stocking density of 6 fish / m 2 , and then start to group broodstock, the number of female fish in each group of broodstock is 2, and the number of male fish is 1 tail, and the...

Abstract

The present invention discloses an egg goldfish breeding method. The method is characterized by comprising the following steps of (1) treating a breeding pool; (2) treating pool water; (3) selecting parent fishes; (4), performing male and female matching on the parent fishes; (5) performing artificial fertilization; (6) performing fish egg incubation; (7) performing fry breeding; (8) performing juvenile fish breeding; and (9) performing adult fish breeding. The parent fishes live in a clean and suitable environment for a period of time before being bred, and the parent fishes are subjected tomale and female matching, so that the fertilization efficiency of the parent fishes is high; the artificial fertilization is started after the breeding peak period is reached, thereby effectively ensuring the formation of fertilized eggs; the parent fishes are subjected to sectional type breeding after fertilization; and different breeding modes are adopted in different growth periods of fries, sothat the growth of the fries is facilitated.

Description

technical field [0001] The invention relates to the technical field of goldfish breeding, in particular to a method for breeding and cultivating egg-laying goldfish. Background technique [0002] Goldfish, biologically belong to the genus Crucian carp of the family Cyprinidae of the order Cypriniformes of the bony fish class, and belong to the same biological species as the crucian carp, and have similar biological characteristics and habits. Goldfish has become a worldwide ornamental fish at present, and occupies an important position in ornamental fish. Egg breed goldfish: The appearance is quite different from crucian carp, with short and fat body, no protruding eyeballs, straight back and no dorsal fin. The rare varieties include red eggs, pompom eggs, phoenix eggs, blister eyes, lion heads, etc. Therefore, the demand for ornamental fish market has been strong in recent years. However, goldfish is a type that spawns once a year, and its natural breeding season is concen...
