Problems solved by technology

These two breeding modes all have the following defects: the exchange of water bodies is too difficult, causing the water body to deteriorate and stink easily during the breeding period, and because it is difficult to control the culture water temperature, it is easy to cause various fatal diseases of blood-suck...

Embodiment Construction

[0038] This blood-sucking leech three-dimensional propagation method comprises the following steps:

[0039] (1) Selection and cultivation of blood-sucking leeches

[0040] The first seed selection time is from March to May, and the blood-sucking leeches that are lively, active, normal in shape and body color, can shrink into a ball quickly when touched with hands and weigh 1.0 to 2.0 g are selected as blood-sucking leeches, so that The blood-sucking leech has a large amount of eggs and a high hatching rate. Then the blood-sucking leech is dropped into the inner layer net cage 7 of the cultivation net cage 5 of the three-dimensional propagation device; Take it out after soaking for 20-40 minutes, wash it with clean water and press 2000-5000 tails / m 2 The density is put into the inner layer net cage 7 of cultivation net cage 5, injects clear water in the outer casing 6 of cultivation net cage 5, makes the water surface height be 8-12 centimetre, will cultivate the inner layer...

Abstract

The invention relates to a three-dimensional breeding method for blood sucking leeches, and belongs to the technical field of blood sucking leech propagation. The method comprises the following steps of 1 blood sucking leech selection and cultivation, 2 leech overwintering, 3 leech mating and cocoon production, 4 cocoon ovum collection and incubation and 5 young leech cultivation. By adopting the method, the blood sucking leech breeding operation steps are simple and convenient to execute, and the mating rate, cocoon yield, hatching rate and survival rate of blood sucking leeches can be greatly increased. By adopting the multi-layer steel frame three-dimensional breeding mode, the occupied area is saved, the blood sucking leech yield per unit area is increased, and the method is particularly applicable to application and popularization in blood sucking leech breeding industrialized production. The problems that due to the fact that existing artificial blood sucking leech breeding water is hard to exchange, the water is likely to go bad or become smelly, due to the fact that the breeding water temperature is hard to control, various diseases are likely to be caused at high-temperature seasons, the parent leech mating rate and the spawning cocoon rate are ow, and the high death rate is caused by empty cocoon, dead cocoon and disease spreading are solved.

Description

technical field [0001] The invention relates to a three-dimensional propagation method of blood-sucking leeches, which belongs to the technical field of blood-sucking leeches propagation. Background technique [0002] Leech is a traditional Chinese medicinal material, its nature and taste are salty, bitter, flat; slightly poisonous. Return liver channel. It has the functions of dispelling blood and dredging menstruation, dispelling blood stasis, and is used for amenorrhea due to blood stasis, abdominal mass, stroke hemiplegia, and injury from falling. Hirudin in leeches is the strongest specific inhibitor of thrombin found so far. Blood-sucking products The anticoagulant activity of leeches was significantly higher than that of non-blood-sucking leeches. However, in recent years, due to the environmental pollution of natural waters, its habitat has been continuously reduced, resulting in a decrease in its population and serious damage to wild resources. [0003] In view o...
