Embodiment 1

[0019] A method for artificial breeding of bream, comprising the following steps:

[0020] (1) Broodstock selection: choose healthy, robust, disease-free, non-injured, and vigorous 2-year-old broodstock, and the ratio of male to female is 1:2 to obtain male and female broodstock;

[0021] (2) Breeding of broodstock: 35 days before the maturation of the gonads of the male and female broodstock, the male and female broodstock are reared in separate ponds, respectively in the female fish pond and the male fish pond, and the male and female broodstock are fed with special agent for broodstock respectively, which is sprayed once a day. The amount of splashing is: 4g / m in the female fish pond 3 , male fish pond 2g / m 3 , feed until 2 days before induced labor, promote gonad maturation, promote germ cell growth, advance the breeding period of bream, and obtain mature male and female broodstock;

[0022] (3) Artificial induction: 2 days before induction, adjust the growth conditions o...

Embodiment 2

[0031] A method for artificial breeding of bream, comprising the following steps:

[0032] (1) Broodstock selection: choose healthy, robust, disease-free, non-injured, and vigorous 2-year-old broodstock, and the ratio of male to female is 1:2 to obtain male and female broodstock;

[0033] (2) Breeding of broodstock: 38 days before the maturation of the gonads of male and female broodstock, the male and female broodstock are reared in separate ponds, respectively in the female fish pond and the male fish pond, and the male and female broodstock are fed with special agent for broodstock respectively. Sprinkle once a day, and the amount of splashing is: 4.5g / m 3 , male fish pond 2.5g / m 3 , feed until 2 days before induced labor, promote gonad maturation, promote germ cell growth, advance the breeding period of bream, and obtain mature male and female broodstock;

[0034] (3) Artificial induction: 2 days before induction, adjust the growth conditions of the broodstock, the temp...

Embodiment 3

[0043] A method for artificial breeding of bream, comprising the following steps:

[0044] (1) Broodstock selection: choose healthy, robust, disease-free, non-injured, and vigorous 2-year-old broodstock, and the ratio of male to female is 1:2 to obtain male and female broodstock;

[0045] (2) Breeding of broodstock: 40 days before the maturation of gonads of male and female broodstock, the male and female broodstock are reared in separate ponds, respectively in the female fish pond and the male fish pond, and the male and female broodstock are fed with special agent for broodstock respectively, and are sprayed once a day. The amount of splashing is: 5g / m in the female pond 3 , male fish pond 3g / m 3 , feed until 2 days before induced labor, promote gonad maturation, promote germ cell growth, advance the breeding period of bream, and obtain mature male and female broodstock;

[0046] (3) Artificial induction: 2 days before induction, adjust the growth conditions of the broodsto...

Abstract

The invention mainly relates to the field of aquaculture technologies, and discloses a method for artificially breeding parabramis pekinensis. The method includes selecting parent fish; cultivating the parent fish; artificially inducing spawning; carrying out artificial insemination; carrying out artificial hatching. The method has the advantages that the method is simple, the reproduction periods of the parabramis pekinensis can be brought forward by 12-15 days, the reproductive capacity of the parabramis pekinensis can be improved and can reach to 8021 roes, and economic income can be increased by 17.3%; the parent fish of the parabramis pekinensis is cultivated in indoor environments, special parent fish feeding agents are splashed, growth conditions required by the female and male parent fish can be regulated, water can be purified, gonad development can be promoted, the disease resistance of the parent fish and the viability of reproductive cells can be enhanced, the fertilization rate can be increased and is 92%, debonding is carried out after fertilization is carried out, debonded liquid is extracted and then is fermented by lactobacillus acidophilus, has appropriate pH (potential of hydrogen), is antibacterial and insecticidal, contains abundant nutrition, is safe and healthful and is debonded quickly, the viability of cells of fertilized roes can be enhanced, and the hatching rate can reach to 91%.

Description

technical field [0001] The invention mainly relates to the field of breeding technology, in particular to an artificial breeding method of bream. Background technique [0002] Bream is a common freshwater fish in my country. It is an omnivorous fish that eats plants. It likes to live in groups and lives by choosing food. Bream meat is tender and has high nutritional value. It is rich in protein and mineral elements, low in fat, and has good health care functions. It can enhance disease resistance, protect cardiovascular and cerebrovascular, strengthen brain and intelligence, nourish blood and nourish deficiency, and beautify skin. [0003] In the current culture method, the fecundity of bream is relatively weak, and the average fecundity is 3436 grains, which increases the cost of culture of bream. Therefore, a new artificial breeding method of bream is needed. Contents of the invention [0004] In order to make up for the defects of the prior art, the purpose of the pres...
