Problems solved by technology

At present, due to the influence of factors such as technical level, environment and natural enemies in the existing artificial seedling raising technology of leeches, the survival rate of leeches is not high, which makes the cost of existing leech breeding high, and large-scale breeding of leeches has received a large industrial level. impact, resulting in the high price of leeches

Embodiment 1

[0019] A kind of culture method of leech, comprises the following steps:

[0020] Step 1) The seedling raising of leeches: put in the leech species in the nursery pond, the throwing density is 5000 / m2, add nutrient solution in the described seedling pond to grow seedlings, the nutrient solution is whey protein powder, puffed blood powder, puffed pomelo peel powder, glucose acid lactone, vitamin B and water to obtain leech seedlings;

[0021] Step 2) selection and preparation of breeding site: choose a pool with a length of 100m, a width of 1m, and a depth of 1m in a cool and humid place, lay 15 cm of breeding soil on the bottom of the pool, soak the breeding soil with povidone-iodine for 8 hours, and then let it go Liquid, then put 20 cm of water, water lilies are planted on the upper part of the pool, an anti-escape wall is set on the top of the pool, and a sunshade device is installed above the pool;

[0022] Step 3) leech throwing: the leech seedlings are put into the pool...

Embodiment 3

[0033] A kind of culture method of leech, comprises the following steps:

[0034] Step 1) seedling raising of leeches: put in leech species in the nursery pond, and the throwing density is 8000 / m2, add nutrient solution in the described seedling pond to grow seedlings, the nutrient solution is whey protein powder, expanded blood powder, expanded pomelo peel powder, glucose acid lactone, vitamin B and water to obtain leech seedlings;

[0035] Step 2) selection and preparation of breeding site: choose a pool with a length of 100m, a width of 1m, and a depth of 1m in a cool and humid place, and lay 20 cm of breeding soil on the bottom of the pool. The breeding soil is first soaked with povidone-iodine for 12 hours, and then released Liquid, then put into 25 cm of water, water lilies are planted on the upper part of the pool, an anti-escape wall is set on the top of the pool, and a sunshade device is installed on the top of the pool;

[0036] Step 3) leech throwing: the leech see...

Abstract

The invention discloses a leech breeding method. The method comprises the following steps: seedling nursery of leeches, selection and preparation of a breeding land; delivery of leeches, leech breeding and management of water quality. The breeding method is simple in operation and low in cost. The survival rate is high during the process of breeding leeches. Secrete of mucus of leech appearance iseffectively simulated because of a nutrient solution. The immunity of leeches is thus promoted. Therefore, the morbidity rate and the mortality of leeches are reduced.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to a method for breeding leeches. Background technique [0002] Leeches, commonly known as leeches, belong to the family Hirudidae. Leeches mainly contain the following components: ① fresh leech saliva contains various anticoagulant components, such as hirudin, hirudin-PA, heparin, antithrombotic factor, etc.; the 64 amino acid polypeptide components also have anticoagulant effect; Hirudin is the most important active substance of the drug, is a specific inhibitor of thrombin, and is a single-chain polypeptide composed of 65 or 66 amino acid residues; hirudin has three varieties, referred to as HV1, HV2, and HV3, all of which have anti Thrombin activity; ②Enzymes and enzyme inhibitors: fresh leech contains a variety of enzymes and enzyme inhibitors, such as glyceryl sphingomyelin lyase, propionylcholinesterase, lipase, cholesterol lipase, allosteric enzyme anti Trypsin active sub...
