Problems solved by technology

However, without artificial intervention before the loach is born, the gonads of the loach grow and mature naturally, which prolongs the breeding cycle. At the same time, the debonding operation is not performed on the fertilized eggs before they hatch, which may easily cause the fertilized eggs to stick and reduce the hatching rate of the fertilized eggs.

Embodiment 1

[0033] The artificial induced spawning method of loach breeding includes the pre-maturity promoting process of parental loach, the artificial induced spawning process, and the fertilized egg hatching process; the fertilized egg hatching process is to intervene in an extreme environment before cultivating and hatching the fertilized eggs. This method of oxytocin takes advantage of the high sensitivity of fertilized eggs to the living environment. When the cells are stimulated by the external environment, they can quickly synthesize protective substances with self-repairing properties to resist these adverse conditions, so that the fertilized eggs can accelerate their initiation. During the period, a higher film production rate, embryo survival rate and hatching rate are obtained, and production costs are saved to meet the large demand for loach seedlings in artificial breeding.

[0034] The extreme environment is an extreme temperature environment, and the specific conditions ar...

Embodiment 2

[0051] Loach culture artificial induced spawning method specifically comprises the following steps:

[0052]1) Prepare a cultivation pond with an overflow device at the bottom, then inject water into the pond and disinfect it for 3 hours, then inject water again, and keep the water temperature in the pond constant at 25°C. The above cultivation pond is disinfected by splashing the whole pond with a mixture of copper sulfate and ferrous sulfate , the dosage of copper sulfate is 1.2g / m 3 , the proportion of copper sulfate and ferrous sulfate is 4.5:2.5, and the above-mentioned overflow device is set as follows: at the bottom of the cultivation pool, the diameter of the upper hole is first laid at the bottom of the pond, and the diameter of the upper hole is 150 meshes, and then the diameter of the mesh is 20 meshes. The edges of both the dense net and the thin net will extend to the edge of the cultivation pool;

[0053] 2) Select a parent loach with a body length of 17cm, a bo...

Embodiment 3

[0060] The method of artificially induced spawning in loach breeding, optimizes the debonding treatment steps, and the specific measures are as follows: When the yield of loach reaches 85%, pull up the thin net in the hatching tank, so that the fertilized eggs of loach can leak to the dense net below in time , then place 4 times the weight of fertilized eggs in the debonding suspension and stir until all the fertilized eggs are in the form of dispersed particles. Suspension prepared by mixing the acid with a weight ratio of 1:0.08:0.04. Since loach eggs are sticky eggs and sinking eggs, after natural mating, the fertilized eggs are easily bonded together. Add to the debonding agent After dextrorotary 4-methyl-2-pentanol and abscisic acid, highly active α and β unsaturated ketone structures and dextro-isomers work together to combine with hydrogen atoms of amino acids in proteins on the fertilized egg cell membrane, thereby generating stimulation It can inhibit the secretion of...

Abstract

The invention provides an artificial induced spawning method for loach culture, and belongs to the field of artificial induced spawning; the method comprises a premature induced spawning process of sexual maturity of parent loaches, an artificial induced spawning process and a fertilized egg hatching process; the fertilized egg hatching process comprises the following steps: placing the fertilizedegg into an extreme temperature or an extreme acidification environment for intervention, and culturing and hatching the fertilized egg; in the prophase maturation promoting process of the sexual maturity of the loach, using the traditional Chinese medicine extract dispersed in the matrix as a gonadal maturation promoting medicament, wherein the traditional Chinese medicine extract is prepared bymagnetizing and leaching traditional Chinese medicine raw materials in the presence of a magnetizing medium containing laurocapram and ethyl decanoate. The artificial induced spawning method for loach culture has the advantages of high efficiency, short spawning and hatching period, high biological activity of the fertilized eggs, low adhesion, no pollution by external germs, high loach seedlingoutput and survival rate and high uniformity; the gonad maturation promoting agent can reduce loach excretion, reduce water body pollution, increase spawning number, improve fertilized egg quality, and reduce death and death amount of parent loach after spawning.

Description

technical field [0001] The invention belongs to the field of artificial induced labor, and in particular relates to an artificial induced labor method for loach breeding. Background technique [0002] Loach belongs to Cyprinidae, Loachidae, Loach subfamily, Loach genus. It is a fish with wide distribution and high economic value. Loach has high nutritional and medicinal value, high protein and low fat, fresh and tender meat, rich nutrition, delicious taste, rich in various vitamins and minerals, and has high nutritional and medicinal value. Loach is a high-protein, low-fat aquatic product. Its meat is tender and nutritious. It is not only a delicacy, but also has high therapeutic value. It is known as "water ginseng" and is a traditional export fish species in my country. Loach has strong adaptability, few diseases, high survival rate, strong fecundity, convenient transportation, easy breeding bait, and low breeding cost. It has become an important freshwater economic fish...
