Problems solved by technology

The paddy farming model has the following problems: on the one hand, the feed conversion rate is low and the harvesting of leeches is extremely difficult;
Neither the current cage culture nor the cement pond culture can solve the problem of leeches' scattered life, especially the problem of how to adjust the water quality in time during the breeding process

Abstract

The invention provides a leech breeding method which comprises the following steps: 1) breeding young leeches, namely selecting healthy seed leeches for cultivation, feeding the seed leeches into an obstetric table for breeding, picking up egg cocoons within 18-25 days, putting the collected egg cocoons into a hatching house, controlling the temperature of the hatching house to be 25-30 DEG C andcontrolling the humidity to be 75-85% for hatching, illuminating the egg cocoons during hatching, and hatching young leeches; 2) treating a water pool, namely injecting water into the water pool, arranging an ecological floating bed on the water surface, arranging No.2 honeysuckle flower on the ecological floating bed, wherein the area of the ecological floating bed accounts for 0.75-0.9 of the area of the water pool, regulating the pH value of the water in the pool to be 6.5-7.5, adding 200-250kg of snails into the pool per mu, enabling the snails to naturally grow and breed so as to provideanimal baits for the leeches; 3) stocking the young leeches; 4) controlling the water level. According to the method, the water quality can be regulated in time, and the breeding density and the survival rate of the leeches are greatly increased.

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] Leech, commonly known as leeches, is the collective name of the animal phylum Hirudophylum in the upper link of animal classification. It grows and reproduces in inland freshwater waters. It is a traditional special medicinal aquatic animal in my country. After its dried products are processed, they are used as medicine in traditional Chinese medicine. , Qingyu, amenorrhea, bruises and other effects, especially for the preparation of Chinese patent medicines for the treatment of cardiovascular and cerebrovascular diseases. In recent years, with the continuous deepening and development of medical research on leeches, the medicinal value has been gradually reflected, and leeches have become one of the world's most in-demand Chinese medicinal materials, and they also have broad application prospects in mo...
