Problems solved by technology

The newly hatched leech seedlings have not yet fully developed, and their adaptability to the environment is relatively poor. After hatching, the leech seedlings like to gather together, which makes it more difficult for the seedlings to eat for the first time. Therefore, a new method is needed to treat the leech seedlings. feed

Embodiment Construction

[0030] The invention provides a method for culturing leeches, comprising the following steps:

[0031] The leech seedling that hatches out is placed in static cultivation box;

[0032] When the leech seedlings just hatched, put the open feed in the static cultivation box;

[0033] The leech seedlings are raised in grades every time they grow one age;

[0034] Along with the growth of described leech seedling, raise the water level in the described resting tank;

[0035] Along with the growth of described leech seedlings, increase the amount of food in the resting tank;

[0036] The water in the outside world is purified by the water preparation pool and then passed into the static cultivation tank.

[0037] Specifically, after the leech seedlings are hatched, the leech seedlings are placed in the resting box, because it is difficult for the leech seedlings to eat, at this time, it is necessary to put an open feed into the resting box to impel the leech seedlings to eat for ...

Abstract

The invention provides a leech culture method comprising the steps of placing hatched leech younglings into a rest culture tank; when the leech younglings are just hatched, putting starter feed into the rest culture tank; performing graded raising once on the leech younglings every time the leech younglings grow for one instar; increasing the water level in the rest culture tank with the growth of the leech younglings; increasing the quantity of feed delivered into the rest culture tank with the growth of the leech younglings; purifying external water by using a water preparing pool and feeding the water into the rest culture tank. The leech culture method can prevent inbreeding and guarantee first feed taking of leech younglings; the method enables leeches to live in an environment suitable for growth consistently, thereby increasing the surviving rate of leeches and increasing the economic benefit.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to a leech breeding method. Background technique [0002] Leech is a general term for the class of Hirudozoa in the upper link of animal classification. There are about 500 species known in the world, divided into 4 orders. There are 2 orders, 8 families, 33 genera and nearly 100 species in my country. Among them, some species of the order Anoscillidae, Phyllididae, Phyllididae, and Lidaceae are closely related to the production and life of human beings. [0003] In the breeding process of leeches, the production and economic benefits of artificially cultured leeches can be improved only by cultivating seed leeches and raising adults. Therefore, mastering the breeding technology is the key to leech breeding. The reproduction of leeches is mainly composed of three main links: courtship and mating, fertilization and egg-laying cocoon and hatching egg cocoon. [0004] After the le...
