Method for high-density green ecological culture of blood-sucking leeches

Abstract

The invention relates to a method for high-density industrial culture of blood-sucking leeches, which belongs to the technical field of artificial culture of the blood-sucking leeches. The culture method cultures commercial leeches artificially by the steps of selecting a place, building a pond, putting leech seeds into the pond, feeding the leech seeds, preparing cocoon producing beds, producing cocoons and hatching the cocoons, culturing young leeches, living through the winter and the like, and achieves recirculation culture by the steps of producing the cocoons and hatching the cocoons. In the culture process, when the reproduction rate of the cultured leeches goes down after three generations of close breeding, the cultured leeches are mated with wild leeches to achieve the aim of the rejuvenescence of parent leeches. The culture method solves the problems that the changes of the natural environment and the increment of pollutant sources make naturally-growing leech sources decrease day by day and the gradually expanded market demand cannot be satisfied. The culture method for culturing the leeches has less investment but high production. The input of 100 kilograms of the leeches can yield 200 kilograms of the commercial leeches. The culture method can culture the leeches not only by building large vinyl tunnels and ponds, but also by using rural homesteads, yards or vacant houses for building the ponds, and has good economic benefits.

Description

Technical field: [0001] The invention relates to a high-density green ecological breeding method for blood-sucking leeches, belonging to the technical field of artificial breeding of blood-sucking leeches. Background technique: [0002] Leech, also known as leeches, natural hirudin made from leech extract is the strongest natural specific inhibitor of thrombin among the known anticoagulant substances found in the world so far; it can expand blood vessels, reduce blood viscosity, increase blood The role of circulation is very significant; it has a good curative effect in the treatment of high blood pressure, stroke, coronary heart disease, arterial thrombosis and other diseases. There are many types of leeches, such as wide-bodied golden leeches, European medical leeches, Japanese medical leeches, Philippine leeches, Amazon giant leeches, etc. Different types of leeches contain different levels of hirudin anticoagulant substances. [0003] There are three kinds of medicinal ...

Problems solved by technology

[0005] The purpose of the present invention is to: provide a breeding density, each cubic meter of breeding volume reaches 5000-30000 tails, leech growth rate is fast, output is large, and the breeding land is saved; The breeding rate is low, the breeding mainly relies on natural stocking in the wild, the breeding density is low, the growth rate is slow, and it cannot meet the growing market demand. The high-density green ecological breeding method of blood-sucking leeches that provides resource guarantee for the application of hirudin,
