Problems solved by technology

Although leeches can lay eggs and hatch in the natural environment, and obtain seedlings, due to the variability of the weather and the influence of natural enemies, the hatching rate of leeches is low, only about 15%, and the hatched leeches have poor physique and are easy to die , which greatly limits the development of leech breeding industry, so there is an urgent need for a scientific and reasonable artificial leech hatching method

Abstract

The invention discloses a leech hatching method. The method comprises following steps: (1), soil on collected egg cocoons is washed off, then the egg cocoons with the pored ends facing upward are put in hatching trays, and 120-140 egg cocoons are put in each hatching tray; (2), the egg cocoons are uniformly covered with hatching soil which is 1-2 cm thick; (3), a hatching solution is sprayed to the hatching soil every three days; (4), the temperature of a hatching room is controlled to be 23-25 DEG C on the 1st-8th days of hatching, the temperature of the hatching room is controlled on the 9th-17th days of hatching, relative air humidity of the hatching room is controlled to be 68%-75% in the hatching period, concentration of carbon dioxide in the hatching room is controlled to be 480-550 ppm, and the hatching trays are irradiated with ultraviolet light for 40-60 min every day. With the adoption of the method, leech egg cocoons can have higher hatching rate and emergence concentration ratio and can shorten emergence cycle of leeches, and hatched juvenile leeches have relatively high immunity, so that the survival rate of the juvenile leeches is increased.

Description

technical field [0001] The invention belongs to the field of leech breeding, and in particular relates to a leech hatching method. Background technique [0002] Leeches, commonly known as leeches, have been recorded in "Shen Nong's Materia Medica", and have high medicinal value; they grow and reproduce in inland freshwater waters, and are traditional Chinese special medicinal aquatic animals. Used as 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 th...
