New method for soilless overwintering of blood-sucking leeches

Abstract

The invention provides a new method for overwintering blood-sucking leeches during indoor cultivation. This method is an indoor soilless overwintering form. The main process is to screen organic fertilizers with a certain thickness, humidity, and granularity in winter as leech overwintering beds, fill them into existing brick cement breeding ponds or special overwintering boxes, and The size of the leeches determines the weight of red earthworms according to a certain weight ratio. Blood-sucking leeches and red earthworms are placed on the bed successively, and the appropriate temperature and humidity are artificially maintained to ensure the safe overwintering of blood-sucking leeches. This method combines the advantages of the two common overwintering methods of leech outdoors in the soil and indoor soilless overwintering, and proposes a unique mode of using red earthworms to cooperate with leeches in overwintering. , Overwintering environment control is convenient and accurate, and the leech overwintering survival rate is high.

Description

technical field [0001] The invention relates to the fields of aquaculture and special animal breeding, in particular to a new method for blood-sucking leeches to survive the winter without soil. Background technique [0002] Leech is a traditional special medicinal aquatic animal in my country. It has the effects of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and bruises. Modern medicine has proved that leeches, especially blood-sucking leeches, are effective in preventing and controlling cardiovascular and cerebrovascular diseases. Significant curative effect. [0003] In recent years, with the increasing pressure of human life and the high incidence of cardiovascular and cerebrovascular diseases, the market demand for blood-sucking leeches has increased year by year, and the price has also risen from 80 yuan per kilogram in 1998 to 280 yuan per kilogram in 2013, and the supply is often in short supply. Due to long-term overfishing and pollution...

Problems solved by technology

[0007] Analyzing the two types of overwintering methods of leeches, the overwintering of outdoor breeding has the advantages of large-scale overwintering and small workload of breeding personnel due to the use of existing ponds and ditches. However, due to regional differences in soil conditions in wintering areas, There are disadvantages such as uneven time and space for leeches to overwinter in the soil, difficulty in collecting data on overwintering seedlings, and difficulty in controlling factors such as temperature and humidity in the overwintering environment, which is a relatively extensive way of overwintering

At present, although the hibernation time of leeches has been synchronized in the indoor anhydrous culture, and the hibernation data is easy to collect, there are still disadvantages such as the direct contact between the leeches and the cement pool, the fluctuations in the hibernation temperature, humidity, and oxygen content of the leeches are too large, and the adjustment is difficult. factor
