Embodiment Construction

[0012] A kind of leech seedling raising method is characterized in that, comprises the following steps:

[0013] (1) Breeding and spawning Select healthy male and female leeches with a ratio of 3:1, induce labor when they are sexually mature, inject chorionic gonadotropin and put them into the birthing bed for mating and spawning;

[0014] (2) Put the eggs into the hatching tank to hatch evenly, put the aeration rod on the edge of the pool, and put the aeration rod on the bottom of the pool after the film is released, and cultivate the leech seedlings;

[0015] (3), clear the pond with quicklime, start watering after 3 days, the water depth is 20-35cm, and then use amino acid to fertilize the water. When the color of the pond water is cultivated to yellow-green, the leech seedlings start to go to the pond, and 100,000 to 120,000 seedlings are put in per mu;

[0016] (4) Use egg yolk as bait for feeding. Use 700g of egg yolk for every 100,000 leech seedlings. After 10 days, use...

Abstract

The invention belongs to the field of breeding, and particularly relates to a young leech culturing method. The young leech culturing method includes the following steps that (1) breeding and spawning are conducted; (2) the spawns are put into a hatching pool to be hatched evenly while oxygenation rods are put on the pool side, the oxygenation rods are put at the bottom of the pool after hatching is conducted, and young leeches are cultured; (3) pool cleaning is conducted through quick lime, water begins to be injected into the pool after 3 days, the water depth ranges from 20 cm to 35 cm, then water manuring is conducted through amino acid, when the color of the pool water turns yellow green through cultivation, the young leeches are put into the pool, and 100-120 thousands of young leeches are put per mu; (4) egg yolks are used as baits for feeding the leeches, and 700 g of egg yolks are used per 100 thousands young leeches. By means of the method, the survival rate of the young leeches reaches 62%, the survival rate of the young leeches is increased, the density of spawns is adjusted by adjusting the positions of the oxygenation rods, the amount of labor is reduced, the cost for culturing the young leeches is reduced, and the economical benefits are increased.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a method for raising seedlings of leeches. Background technique [0002] Leeches, commonly known as leeches and horse turtles, belong to the phylum Annelids, class Hirudophylum, order Hirudidae, and family Hirudoceae. They grow and reproduce in inland freshwater waters. They are traditional special medicinal aquatic animals in my country. Hinders blood coagulation, thus has anticoagulant effect. Its dry products are processed and used as medicine in traditional Chinese medicine, which has the effects of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and traumatic injuries. However, the survival rate of leeches is low when they are cultured. Contents of the invention [0003] In order to solve the problem of low survival rate in the current leech seedling raising process, the invention provides a leech seedling raising method, which improves the sur...
