Example Embodiment

[0022] Example 1 Breeding of leech seedlings

[0023] (a) Hatching: In late April, put the leech eggs into an incubator for incubation, which is composed of a foam box and a hatching substrate laid in the foam box, and is observed several times a day;

[0024] (b) Seedling emergence: When small black spots appear on the leech eggs, place the leech eggs with small black spots on a foam plate with a length of (5-10) cm × (5-10) cm, and make the foam plate float on Cover the leech eggs with absorbent cloth on the water in the nursery pond, and soak the two or four sides of the absorbent cloth in the water; 15-20 days later, all leech eggs will emerge, and the emergent leech will enter the nursery pond water by itself, and take out the foam plate and absorbent cloth;

[0025] (e) The growth and daily management of leech seedlings: grow leech seedlings in nursery ponds, keep the greenhouse temperature 25-30℃, humidity 40-50%, and nursery pond water temperature 22-25℃; cultivate water hyac...

Abstract

The invention provides a leech fry raising method which comprises the following steps: 1) hatching: hatching leech eggs in a hatching box, wherein the hatching box comprises a foam box and hatching substrate spread in the foam box; 2) obtaining fries: when small black spots appear on the leech eggs, putting the leech eggs with small black spots onto a foam plate, floating the foam plate on pond water of the fry culturing pond, covering the leech eggs with the water absorbing cloth, immersing two edges or four edges of the water absorbing cloth into the water, causing the leech eggs to completely hatch in 15-20 days, causing the hatched leeches to automatically enter the pond water of the fry culturing pond, and taking out the foam plate and the water absorbing cloth; and 3) raising the young leeches: raising the young leaches in the fry culturing pond. The leech fry raising method disclosed by the invention has the advantages of high survival rate of young leeches, is simple to operate and is suitable for large scale production.

Description

technical field [0001] The invention relates to a method for raising seedlings of leeches. Background technique [0002] Leeches are important Chinese herbal medicines in my country. It is recorded in "Chinese Pharmacopoeia" 2010 that leeches have the effect of "breaking the blood and stimulating the menstrual flow, removing blood stasis and eliminating lumps, and can be used for blood stasis amenorrhea, lame lumps, stroke hemiplegia, and injury from falls." , is the main raw material of many Chinese patent medicines for the treatment of cardiovascular and cerebrovascular diseases. The natural hirudin made from leech extract is the strongest natural specific inhibitor of thrombin among the known anticoagulant substances found in the world so far. It is very effective in dilating blood vessels, reducing blood viscosity, and increasing blood circulation. Significant; it has a good curative effect in the treatment of hypertension, stroke, coronary heart disease, arterial thromb...
