Problems solved by technology

Historically, it was mainly caught by natural fishing. Due to the abuse of pesticides and chemical fertilizers in recent years, and the pollution of the environment by the "three wastes" of industry and agriculture, the wild natural resources have declined sharply. With the in-depth development of the medicinal value of leeches, its market demand potential is huge. At present, wild leeches are mostly sourced from rivers, reservoirs or swamp ponds. The unstable water quality will lead to low safety factor of leeches. The existence of a large number of fungi and bacteria can increase the chance of cross-infection. It is not suitable for direct use in medical treatment. Therefore, artificial Breeding leeches is imperative
Yet in the artificial rearing method of leech at present, the selection of leech, the selection and use of feeding feed and the difference of feeding conditions such as water temperature, PH value, water oxygen content will cause its body weight and blood-sucking ability to be low, and the number of colonies contained in the leech body is relatively small. Many and contain more parasitic protozoa and low survival rate

Abstract

The invention provides a method for breeding medical leeches. The method includes steps of preparing the leeches; preparing purified water and a breeding pond; releasing the leeches in the breeding pond; feeding the leeches; keeping the leeches; managing the leeches and acquiring finished products; and storing the finished products. The method has the advantages that the method is an assorted method for breeding the leeches by means of optimizing species of the leeches, the blood sucking ability of the leeches is strengthened, a death rate of the acquired leeches is low; and feeding conditions such as the temperature of the water, a pH (potential of hydrogen) value, the oxygen content of the water and the fasting time are optimally matched according to multiple experiments, so that numbers of bacterial colonies and parasitic protozoa in the leeches are quickly reduced and are close to the lowest levels along with increase of fasting days, and the service safety of the medical leeches is guaranteed.

Description

technical field [0001] The invention relates to a feeding method for leeches, in particular to a feeding method for medical leeches. Background technique [0002] Leech, commonly known as leech, grows and reproduces in inland freshwater waters. It is a traditional special medicinal aquatic animal in my country. Its dried products are processed and used in traditional Chinese medicine. It has the effects of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and traumatic injuries. In recent years, it has been newly discovered that leech preparations have special effects in the prevention and treatment of cardiovascular and cerebrovascular diseases and cancer. Historically, it was mainly caught by natural fishing. Due to the abuse of pesticides and chemical fertilizers in recent years, and the pollution of the environment by the "three wastes" of industry and agriculture, the wild natural resources have declined sharply. With the in-depth development of t...
