A kind of steel frame floating net leech high-density breeding method

Abstract

The invention relates to a hirudo high-density culture method with a steel frame floating net, and belongs to the technical field of large-scale hirudo culture. The hirudo high-density culture method with the steel frame floating net is characterized in that supporting steel frames, floating net cages, foam cylindrical floaters and the like are arranged, by means of the eight steps of the hirudo high-density culture method with the steel frame floating net, high-density, high-yield and high-quality hirudo culture is achieved, and the survival rate and finished product output rate of hirudo are greatly increased. The yield per mu can maintain stability within about 1000 kg to 1250 kg, the yield is increased by 150%, and the economic benefit of culturists is greatly improved. An aerator drives the floating net cages to swing and enhances fluctuation quantity of water bodies to rapidly complete water body exchange; an adequate amount of hydrophyte is added to enhance water purification capacity of the water bodies in culture areas, water transfer is conducted at the right moment, and the cleanliness of the culture water bodies is kept. The problems that for an existing conventional culture mode, the water body exchange is difficult, the hirudo is quite prone to infection due to the fact that the water temperature is uncontrolled, the water deteriorates and the temperature of the water bodies is high, and the quality of the survival hirudo and the yield per unit area are greatly affected are solved, and the hirudo high-density culture method with the steel frame floating net is suitable for culturing the hirudo in lakes, reservoirs, paddy fields and ditches.

Description

technical field [0001] The invention relates to a method for high-density breeding of leeches with steel frame floating nets, and belongs to the technical field of large-scale leech breeding. 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, and it is also a rare and precious Chinese medicinal material that is sold well at home and abroad. Dried leech products are processed and used as medicine, which has the effects of treating stroke, high blood pressure, clearing blood stasis, and traumatic injuries. In recent years, with the in-depth development of the medicinal value of leeches, natural resources have been decreasing day by day, and the contradiction between supply and demand in the market has become prominent. Artificial breeding of leeches has become a brand-new wealth-generating industry. It is also a spark technology project protected by ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a method for high-density cultivation of leeches with steel frame floating nets, which is convenient for water exchange, good in breeding water quality, adjustable in water temperature, high in leech quality, high in yield per unit area, and wide in scope of application; solves the problem of existing conventional breeding models Because the water exchange is too difficult, the water temperature cannot be adjusted, which leads to the deterioration of the smelly water and the high-temperature water. Breeding leeches is very susceptible to diseases, which seriously affects the quality of surviving leeches and the yield per unit area.
