Embodiment Construction

[0016] A kind of culture method of leech, comprises the following steps:

[0017] (1) Breeding of leeches: Select healthy leeches for cultivation, put the leeches into the production bed for reproduction, harvest egg cocoons after 18-25 days, put the collected egg cocoons into the hatching room, and control the temperature of the hatching room at 28 Incubation at -31°C and humidity of 75-85%, light the egg cocoons during incubation, and hatch the seedlings;

[0018] (2) Treatment of the pool: set the pool in deep water area and shallow water area, set up a bank slope in the pool, plant broad-leaved aquatic plants on the bank slope to facilitate the habitat of leeches, plant aquatic plants in the water, increase the amount of dissolved oxygen in the water, and adjust The pH of the pool water is 7.0-9.0, and 200-250kg of snails are placed in the pool per mu to allow them to grow and breed naturally, providing animal bait for the leeches;

[0019] (3), stocking of leech seedling...

Abstract

The invention belongs to the field of aquaculture, and particularly relates to a leech breeding method. The leech breeding method comprises the following steps: (1) leech fry are grown; (2) a pool is processed; (3) the leech fry are bred; (4) the water level is controlled, bacilli and EM probiotics are applied to water in the pool for water quality regulation. According to the leech breeding method, by means of improving a breeding method, the survival rate in the leech breeding process is increased, the stocking density is also increased, and the economic benefit of breeding is increased.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating 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. Hinder blood coagulation, thus have 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. As a new industry in modern agriculture, medicinal leech breeding is not difficult to raise, but the survival rate of breeding is low, and high-density breeding cannot be carried out. Contents of the invention [0003] In order to solve the defect of low survival rate in the existing l...
