The invention discloses a method for cultivating high-yield leeches indoors, which comprises the following steps: 1) building a culture pond; 2) seedling culture; 3) breeding in growing period; 4) harvest.
The breeding pond used in the invention is small, the feeding management is convenient, the pure snail ecological feeding is adopted, the management is strict, the yield is high, and the net bag is used for pure natural fishing, which is convenient and fast.
This patent describes an indoor cultivation method of high-yield leech.
Technical field
[000 1] The invention relates to the field of aquaculture, in particular to an indoor high-yield leech cultivation method.
technical background
Leech is a gregarious animal that likes light, shade and hunger. According to the living habits, behavior habits, physiological habits, growth habits and climate environment of leeches in nature. Leech is a precious raw material of Chinese herbal medicine, which is in short supply at home and abroad. Can be used for treating traumatic injury, hypertension, coronary heart disease and tumor. Its medicinal value determines its future market situation. Judging from the consumer market, China is the first country to use leeches. With the development of domestic medicine and the further development of medicinal value of leeches, the demand for leeches is increasing.
[0003] The existing leeches are usually cultured in an external pond, which usually leads to the increase or decrease of leech yield due to the influence of external weather and the killing of leeches by various external birds, which has a great influence. Moreover, the leeches intensively cultivated are of different sizes and poor quality. When leeches are raised, they are usually given a variety of feeds, which are complicated and unstable. However, when fishing, it is often necessary to catch leeches by external dosing, which reduces the quality of leeches and the sales price of leeches. Meanwhile, leeches cultivated in the prior art have a yield of about 500-700 kg per mu, and the yield is low.
