Embodiment Construction

[0016] The present invention will now be described in further detail with reference to the embodiments.

[0017] A method for collecting leech seedlings. The inner wall of a seedling pond filled with water is smooth, and after the leech seedlings hatch and emerge in the seedling pond, they are distributed on the inner wall of the seedling pond and the water in the seedling pond. Collecting is carried out until all the leech seedlings are collected cleanly, the fishing net is used to collect the leech seedlings in the water, and the sponge is used to collect the leech seedlings on the inner wall of the nursery tank.

[0018] Alternate use of scoop nets and sponges will allow you to collect as many leech seedlings as possible without missing any.

[0019] The inner wall of the cement-stacked seedling pond is affixed with a marble slab, the surface of the marble slab is smooth, and the leech seedlings are relatively soft. The wall is conducive to collecting leech seedlings, espe...

Abstract

The invention relates to a collecting method for leech larva. The method is that the inner wall of a culture tank filled with water is smooth, leech larva disperse to the inner wall of the culture tank and water in the culture tank after incubation from the culture tank. The method is characterized in that a collecting net and sponge are alternatively used for collecting the leech larva until all the leech larva are collected; the collecting net is used for collecting leech larva from the water, and while the sponge is used for collecting leech larva from the inner wall of the culture tank. According to the method, the sponge and the collecting net are used for collecting the leech larva, so that the phenomenon that the leech larva is broken and killed during collecting can be basically avoided; meanwhile, the collection is simple, convenient and quick; the technical scheme of draining water from the tank is performed for collecting all the leech larva to the maximum, and therefore, any waste is avoided.

Description

technical field [0001] The invention relates to a leech culture technology, in particular to a method for collecting leech seedlings. Background technique [0002] Leech, commonly known as leech, grows and breeds in inland freshwater waters, and is a traditional special medicinal aquatic animal in my country. Its dried products are processed into traditional Chinese medicine. With the abuse of pesticides, chemical fertilizers, etc. caused by the development of modern society, as well as the pollution of industry and agriculture to the environment, wild natural resources have declined sharply. With the in-depth development of the medicinal value of leeches, its market demand potential is huge, and leeches have historically been caught naturally. Mainly, the factory farming of leeches is a historical innovation. [0003] Leech seedlings are gregarious and will gather together. They will die or break with a little force. During the collection process, appropriate tools should ...
