A kind of leech breeding breeding box

Abstract

The invention discloses a leech reproduction culture tank comprising a tank body and a spawning and rest platform fixed to the inner side of the side wall of the tank body. Being provided with the spawning and rest platform, the leech reproduction culture tank integrates leech reproduction and culture and can effectively block leeches from escaping, a concealing and spawning place is provided for spawning leeches, the leeches can mate, spawn and rest quietly during reproduction, mating rate and spawning rate of the leeches are increased greatly, hollow cocoon rate and dead cocoon rate are lowered, the leeches can recover physical strength and relieve fatigue quickly and favorably after delivery, the purpose of lowering death rate of postpartum parent leeches is achieved, the culture tank has a certain function of moisture retention on leech cocoons, the problem that the fry is difficult to incubate due to dryness of the cocoons is prevented, in addition, culture personnel can take out the leech cocoons on the spawning and rest platform anytime for incubation, and operation is simplified.

Description

technical field [0001] The invention relates to the field of aquaculture devices, in particular to a leech breeding and breeding device. Background technique [0002] Leech (leech) is a traditional medicinal aquatic animal in my country and the basis of traditional Chinese medicine "leech". The "Chinese Pharmacopoeia" stipulates that the animal sources of "leech" are Japanese medical leech, broad-bodied golden leech, and willow leaf leech. Its dried products are used as medicine in traditional Chinese medicine after being processed. It has the effects of treating cardiovascular and cerebrovascular diseases, stroke, high blood pressure, amenorrhea, cataract, etc. The curative effect of leeches has led to a shortage of leech medicinal materials, showing great market demand and economic benefits. The extensive development of medicines and the widespread use of chemical fertilizers and pesticides have led to the predatory exploitation of wild leeches and the depletion of resour...

AI Technical Summary

Problems solved by technology

However, when using breeding boxes for artificial reproduction and breeding, leeches are prone to escape, the pro-leech mating rate and egg-laying cocoon rate are low, and empty cocoons and dead cocoons are prone to appear, and the egg cocoons produced are difficult to obtain reasonable moisture retention. As a result, the leeches after the egg-laying cocoon are weak and unable to recover their physical fitness, resulting in a high mortality rate

Therefore, leech breeding and breeding in indoor breeding boxes has always been a problem that makes leech farmers very entangled, and has not been effectively solved for a long time
