Abstract

The invention relates to a method for breeding leeches. The method comprises the steps of: putting leech eggs into an incubator for hatching, and when small and black spots emerge on 80% or above of the leech eggs, transferring the leech eggs a seed nursery pool in which no any substances are put; when hatching of the leech eggs is conducted completely, adding a nutrient solution which is made from whey protein powder, expanded blood powder, expanded pomelo peel powder, glucolactone, vitamin B and water into the seed nursery pool for fry raising so as to obtain seed leeches; laying a substratewhich is made from expanded pebbles, expanded quartz and polyethylene particles on the bottom of a pool, and planting polygonum hydropiper, snowpoppy and lotuses in water of the pool; and putting theseed leeches into the pool, and putting seed margarya melanioides into the pool at the same time. According to the method for breeding the leeches, through the plantation of polygonum hydropiper, snowpoppy and lotuses in the water of the pool, not only can a growth environment be provided for the leeches, but also the anti-bacteria effect of the three planted plants can be utilized, so that the occurrence of leech diseases is reduced, and the survival rate of the leeches is improved.

Description

technical field [0001] The invention relates to the technical field of leech cultivation, 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 a...
