Embodiment 1

[0013] The out-of-season fish breeding method of the present embodiment comprises the steps:

[0014] (1) Construction of the breeding pool: build a greenhouse, and establish the parental breeding pool and the F1 generation breeding pool in the greenhouse. The magnetic field generator, refrigeration components, and heating components are placed on the parental breeding pool, and the refrigeration components and heating components are placed in the F1 generation breeding pool. Components, refrigeration components and heating components are wrapped with waterproof casings;

[0015] (2) Magnetic field treatment of parental fish: put the fertilized eggs just laid by the fish into the parental breeding pond, and introduce a changing electromagnetic field into the parental breeding pond for 2 hours, and the strength of the electromagnetic field is 0.35±0.15 A / m From strong to weak and then strong within the range;

[0016] (3) Cold and heat change treatment of parent fish: the firs...

Embodiment 2

[0019] The out-of-season fish breeding method of the present embodiment comprises the steps:

[0020] (1) Construction of the breeding pool: build a greenhouse, and establish the parental breeding pool and the F1 generation breeding pool in the greenhouse. The magnetic field generator, refrigeration components, and heating components are placed on the parental breeding pool, and the refrigeration components and heating components are placed in the F1 generation breeding pool. Components, refrigeration components and heating components are wrapped with waterproof casings;

[0021] (2) Magnetic field treatment of parent fish: Put the fertilized eggs just laid by the fish into the parent breeding pond, and introduce a changing electromagnetic field into the parent breeding pond. From strong to weak and then strong within the range of / m;

[0022] (3) Cold and heat change treatment of parent fish: the first stage of temperature rise and fall: in late spring and early summer, the ...

Abstract

The invention discloses an anti-season fish propagation method comprising the steps such as construction of a culture pond, magnetic field treatment of parent fishes, cold and hot varied treatment ofthe parent fishes and strengthening treatment of an F1 generation. By using the method disclosed by the invention, the breeding period can be effectively shortened, the high and low temperature resistance of fishes can be improved, guarantees are provided for anti-season fish culture, the difficulty of anti-season culture of common fishes is lowered, the survival rate is increased by 88% or above,and the economic benefits of farmers are increased.
