Cultivation method of indoor high-yield leech

Abstract

The invention discloses a cultivation method of indoor high-yield leech. The method comprises the following steps of 1) building a cultivation pond; 2) cultivating seedlings; 3) cultivating in the growth period; 4) harvesting. The cultivation pond used in the cultivation method is small, the feeding and management are convenient, pure spiral shells are adopted to ecologically feed and harshly manage, the yield is high, the natural fishing is realized by a net bag, and the operation is convenient and rapid.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating indoor high-yield leeches. Background technique [0002] Leech is a social animal that avoids light and prefers shade, and is resistant to hunger. It aims at the living habits, behavioral habits, physiological habits, growth habits and climate environment of leeches in nature. Leech is a rare and precious Chinese medicinal raw material that is in short supply at home and abroad. It can treat bruises, high blood pressure, coronary heart disease and tumors. Its medicinal value determines its future market status. From the perspective of the consumer market, my country is the earliest country to use leeches. With the development of domestic medicine and the further development of the medicinal value of leeches, the demand for leeches is increasing day by day. In addition, Europe and the United States have a large consumer market, and Japan, North Korea, and South...

Problems solved by technology

However, in recent years, due to the large-scale use of pesticides, chemical fertilizers and pollution of the chemical industry, wild resources have declined sharply, and the medicinal uses of leeches have been continuously explored, resulting in a prominent contradiction between market supply and demand, creating a broad market prospect for artificial breeding of leeches

[0003] Existing leeches are usually cultured in external ponds during the breeding process. This method usually causes leeches to increase or decrease production due to external weather influences and external various birds during breeding, which has a greater impact

Moreover, the densely farmed leeches are of different sizes and of poor quality

When feeding, leeches are usually given various feeds, which are mixed and unstable

When fishing, it is often necessary to catch leeches by external dosing, which reduces the quality of leeches and reduces the sales price of leeches. At the same time, the leeches cultivated in the prior art produce about 500-700 jin per mu, and the output is relatively low.
