Problems solved by technology

With the development, development and promotion of Chinese patent medicines related to leeches, the demand for leeches is increasing year by year. However, the shortage of wild leeches is far from being able to meet the huge supply demand in the market, so artificial breeding is urgently needed to fill the huge market. supply gap
Judging from the currently mastered leech breeding technology, most of the farming methods have problems such as low feed conversion rate, difficulty in harvesting leeches, and decline in leech quality and yield. Therefore, it is urgent to develop a better breeding method

Abstract

The invention discloses a leech culture method and belongs to the technical field of aquaculture. The method specifically comprises the following steps: (1) building an aquaculture cage; (2) arranging a culture pond; (3) putting in young leeches; (4) performing feeding management; and (5) performing water quality management. According to the method disclosed by the invention, the yield and quality of leeches can be effectively improved, the yield can be improved by about 30%, the activity of antithrombin in the leeches is well enhanced, and the application value is high.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating leeches. Background technique [0002] Leeches, commonly known as leeches, are cold-blooded annelids that move very quickly. They can swim like waves and migrate like inchworms. It can grow and reproduce in the north and south of our country, and mainly lives in reservoirs, ditches, paddy fields, lakes and swamps in fresh water, and it is most abundant in ponds rich in organic matter or in small rivers without pollution. Leech is a traditional special medicinal aquatic animal in my country. Its dried products can be used as medicine after brewing. It has the effects of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and traumatic injuries. With the development, development and promotion of Chinese patent medicines related to leeches, the demand for leeches is increasing year by year. However, the shortage of wild ...
