Embodiment 1

[0021] This leech seedling breeding method is as follows:

[0022] A. Arranging the rearing pond: Inject water into a breeding pond with a water inlet system and a drainage system with an area of ​​1 mu and a depth of 50cm. Stop water injection when the water depth is 25cm, keep the water temperature at about 25°C, and then put 20kg of camellia bran and 100g Endosulfan, after one week, set up a floating raft of watery vegetables in the middle of the rearing pond. This floating row of watery vegetables includes a floating frame made of polyvinyl chloride hard rubber tube and a small section of rubber hose that is arranged inside the floating frame at intervals. The small section of the rubber hose is provided with a through hole and filled with mud, and the cuttage of the through hole is planted with watery vegetable stems.

[0023] B, put in nutrients: Put in nutrients 20 days after step A, the nutrients are composed of sodium humate, bacillus compound preparation, photosynthe...

Embodiment 2

[0029] This leech seedling breeding method is as follows:

[0030] A. Arranging the rearing pond: Inject water into a breeding pond with a water inlet system and a drainage system with an area of ​​1 mu and a depth of 60cm. When the water depth is 30cm, stop the water injection, keep the water temperature at about 25°C, and then put in 30kg of camellia bran and 100g Endosulfan, after one week, set up a floating raft of watery vegetables in the middle of the rearing pond. This floating row of watery vegetables includes a floating frame made of polyvinyl chloride hard rubber tube and a small section of rubber hose that is arranged inside the floating frame at intervals. The small section of the rubber hose is provided with a through hole and filled with mud, and the cuttage of the through hole is planted with watery vegetable stems.

Abstract

The invention discloses a leech fry breeding method and relates to the technical field of leech breeding. The leech fry breeding method comprises the following steps: arranging a breeding pond, putting breeding water nutrients into the breeding pond, putting leech fries into the breeding pond, putting feed into the breeding pond, performing breeding observation, transferring leeches into differentbreeding ponds, and the like. Certain amounts of tea bran and insecticides for sterilization are put into the breeding pond after water is fed into the breeding pond, the problem of natural enemies is solved, water spinach is further planted, and thus a natural, ecological, healthy and appropriate growth environment is established; and the feed is put into sausage casings and is fed to the leechfries as a whole, then no residues, blood coagulation wastes or putrefaction is generated, water bodies are not polluted, and the feed is also prevented from being hurt or killed by pinching of snails, so that the survival rate and the yield of the leech fries are increased. By adopting the method, the problems that the survival rate and the yield of leech fires are low as water bodies can be easily polluted in the leech fry breeding process, and the feed is hard to take and utilize by the leech fires, are solved.

Description

technical field [0001] The invention relates to the technical field of leech cultivation, in particular to a method for cultivating leech seedlings. Background technique [0002] Phnom Penh leech, Poecilobdellamanillensis, a species of verdiliaceae, is a characteristic medicinal animal resource in Guangxi. The natural hirudin secreted by the salivary glands of Hirudo phenanthae is the strongest natural antithrombin substance among the known substances found in the world so far, and it has a high curative effect on the treatment of cardiovascular and cerebrovascular diseases, especially cerebral apoplexy. In recent years, with the sharp increase in global demand for leeches, artificial overfishing has depleted natural resources and caused a serious imbalance between supply and demand. Artificial breeding is an effective solution to solve the shortage of wild leech resources. [0003] At present, the problem of low survival rate of leech seedlings generally occurs in the art...
