Leech ecologicalization purse net cultivation method

Abstract

The invention relates to a leech ecologicalization purse net cultivation method and belongs to the technical field of large-scale leech cultivation. The method is characterized in that a cultivation base pond, a purse net, a water changing pipeline, aquatic plants and microecologics are included, a virtuous circle food chain is established through ten steps, the purifying capacity of the aquatic plants is used for improving and stabilizing water quality, natural growing and reproduction of spiral shells are promoted, the spiral shells, plankton and conventional nutrients are matched to form mixed feed, so that one-month-old leeches obtain rich nutrition, following young leeches are good in activity and quick in growing, and the death rate is greatly lowered. Through the water changing pipeline, water replenishing and water changing management is convenient, water quality can be adjusted easily, the survival rate of leeches from the one-month-old leeches to grown leeches is effectively improved, and stable and high yield of the grown leeches are guaranteed. The problems that in the prior art, water quality cannot be adjusted, management is not convenient, a cultivation facility and a cultivation process are not reasonable, so that the leech death rate is high, the finished product rate is low, and stable and high yield cannot be guaranteed easily are solved. The technology is simple, investment cost is low, and market application prospect is wide.

Description

technical field [0001] The invention relates to an ecological purse seine culture method for leeches, which belongs to the technical field of large-scale leech culture. Background technique [0002] Leeches are an important basic Chinese medicinal material. Due to the dwindling resources of wild leeches, the contradiction between supply and demand in the Chinese medicinal material market is prominent. Therefore, artificial breeding of leeches came into being, which alleviated the contradiction between supply and demand in the Chinese medicinal material market to a certain extent. However, most of the existing purse seine farming models have problems such as unreasonable breeding facilities and breeding procedures, inability to control water quality, inconvenient management, high leech mortality rate, and low yield of finished products. The contradiction between supply and demand in the Chinese herbal medicine market seriously affects the economic benefits of leech farmers. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a virtuous cycle chain that can make leeches, aquatic plants, and leech food grow together and complement each other. The water quality is easy to control, and the management is convenient. The survival rate from full-moon seedlings to finished leeches effectively ensures the stable and high yield of finished leeches. The leech ecological seine breeding method solves the problem that the existing technology cannot regulate water quality, inconvenient management, unreasonable breeding facilities and breeding procedures, resulting in high mortality of leeches. The yield rate is low, and it is difficult to ensure stable and high production
