Embodiment 1

[0037] Embodiment 1: A kind of seedling raising method that industrialized artificial propagation of loach improves survival rate, comprises the following steps:

[0038] A. parent selection

[0039] Choose parents with healthy physique, normal color and strong activity, and feed them water earthworms for 3 to 5 days;

[0040] B. induced labor

[0041] At a water temperature of 24-28°C, artificially induce labor on the female parent, and the injection drug is luteinizing hormone-releasing hormone A 2 125mg, 100mg of dipridone (Diortone), 80cc of normal saline, mixed injection of the three, intramuscular injection, no drug injected into the abdominal cavity, 0.5cc per injection; when injecting, place a 0.5~1cm thick pad on the operating table Make a circle with a diameter of 15cm, and sew gauze on it to cover the parents of loach placed on the cotton felt, so as to avoid catching with hands and damage the parents of loach;

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a breeding method for increasing the survival rate of loaches manually bred in a factory-like mode, wherein the breeding method is reasonable, simple and high in operability. According to the breeding method, the natural mating method, the sperm extrusion method and the laparotomy spermatophore-obtaining method can be adopted, the death rate of parent fish for breeding can be greatly reduced, and the spawning induction rate, the fertilization rate and the hatching rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a seedling raising method for industrialized artificial propagation of loach to improve the survival rate. Background technique [0002] Loach has lower fat content, less cholesterol, high-protein and low-fat food, and contains an unsaturated fatty acid similar to eicosapentenoic acid, which is beneficial to the human body's anti-vascular aging, and is beneficial to the elderly and cardiovascular patients. It has the effects of invigorating the middle and replenishing qi, dehumidifying and reducing jaundice, nourishing the kidney and supporting yang, dispelling dampness and stopping diarrhea, warming the spleen and stomach, treating hemorrhoids, and stopping sweating due to sweating. Known as "the ginseng in the water". [0003] In recent years, the scale of loach farming has developed rapidly, and the Miao nationality has become a bottleneck restricting the deve...
