Problems solved by technology

At present, the bait of leeches is mostly green snails. In water, because the shell of green snails is hard, small leeches will enter the screw through the opening cover of the screw to feed. At this time, the leech is easily caught by the screw.

Embodiment 1

[0007] In pool water with a certain pH, maintain a certain oxygen content in the water, put a certain amount of leech seedlings and apple snail seedlings for the first time, change to 2 pools after 10 days, change to 4 pools after 10 days, and put them in cages after 10 days ; The leech seedlings and the apple snail seedlings correspond in size, the small leech seedlings correspond to the small apple snail seedlings, and the large leech seedlings correspond to the large apple snail seedlings; the described pH is pH=6; the described oxygen content is 0.7mg / L described small leech, its initial release amount is: 3000 tails / square; described small apple snail, its daily release amount is 15kg / mu; No more than 0.6mm; the leech seedling is a leech seedling less than 3g.

Embodiment 2

[0009] In pool water with a certain pH, maintain a certain oxygen content in the water, put a certain amount of leech seedlings and apple snail seedlings for the first time, change to 2 pools after 10 days, change to 4 pools after 10 days, and put them in cages after 10 days Inside; described leech seedlings and apple snail seedlings have corresponding sizes, small leech seedlings correspond to small apple snail seedlings, and large leech seedlings correspond to large apple snail seedlings; the described pH is pH=8.5; the described oxygen content is 2.0mg / L; described small leech, its initial release amount is: 3000 tails / square; described small apple snail, its daily release amount is 30kg / mu; , no more than 0.6mm; the leech seedling is a leech seedling less than 3g.

Embodiment 3

[0011] In pool water with a certain pH, maintain a certain oxygen content in the water, put a certain amount of leech seedlings and apple snail seedlings for the first time, change to 2 pools after 10 days, change to 4 pools after 10 days, and put them in cages after 10 days The leech seedlings and the apple snail seedlings have corresponding sizes, the small leech seedlings correspond to the small apple snail seedlings, and the large leech seedlings correspond to the large apple snail seedlings; the described pH is pH=7; the described oxygen content is 1.5mg / L ; said small leech, its initial feeding amount is: 3000 tails / square; said small apple snail, its daily feeding amount is 20 leech seedlings, which is less than 3g of leech seedlings.

Abstract

The invention relates to a cultivation method of juvenile leech. According to the method, certain oxygen content in pool water with a certain potential of hydrogen value is kept, and a certain amount of juvenile leech and juvenile ampullaria gigas are put in for the first time, are put into 2 changed pools after 10 days, are put into 4 changed pools after 10 days, and are put into a net cage after 10 days, wherein the juvenile leech and the juvenile ampullaria gigas are corresponding in size, small juvenile leech correspond to small juvenile ampullaria gigas, and big juvenile leech correspond to big juvenile ampullaria gigas. According to the method for feeding the leech with the ampullaria gigas, each ampullaria gigas has a soft shell and is oviparous (acmaea is viviparous), so that manual collection can be realized, and the yield is high. Because each small ampullaria gigas has the soft shell, and can be directly eaten by the small leech, the phenomenon that the leech is clamped and killed by the small ampullaria gigas does not exist.

Description

technical field [0001] The invention relates to the field of cultivation, in particular to a method for cultivating leech seedlings. Background technique [0002] Leeches are a kind of traditional Chinese medicinal material with high economic value, but the economic value of leeches depends on the individual size of leeches, and the individual size of leeches depends on whether the open bait can be eaten. At present, the bait of the leech is mostly green snails. In water, because the shell of the green snails is hard, small leeches will enter the screw through the opening cover of the screw to feed. Contents of the invention [0003] In pool water with a certain pH, maintain a certain oxygen content in the water, put a certain amount of leech seedlings and apple snail seedlings for the first time, change to 2 pools after 10 days, change to 4 pools after 10 days, and put them in cages after 10 days The leech seedlings correspond to the size of the snail seedlings, the ...
