Embodiment 1

[0022] A high-density artificial breeding method of wide-body leeches, comprising the steps of:

[0023] (1) Build a breeding pond: choose a place that is convenient for drainage and irrigation, and build a breeding pond in a place that is sheltered from the wind and facing the sun, and build a greenhouse with adjustable height on the breeding pond;

[0024] (2) Placement of aquaculture substrate: inject water into the aquaculture pond, put money into the bottom of the pond, plant aquatic plants on the water surface, and the planting area accounts for 1 / 5 of the aquaculture area;

[0025] (3) Nesting apple snails and / or field snails: Aquatic plants planted on the water surface can grow apple snails and / or field snails;

[0026] (4) Seedling release: select leech seedlings with a weight of 0.3-0.5 grams / piece, and stock them at a density of 3,000 / square meter;

[0027] (5) Feed feeding: feed the seedlings after 3 days, and feed on snails, mussels, plankton, and clear juice...

Abstract

The invention relates to a high-density artificial culturing method of wide body leeches. The method comprises the steps that 1. a culturing pond is built; 2. culturing matrixes are placed; 3. ampullariagigas and/or escargots are subjected to mixed culturing; 4. the young is put in; 5. fodder feeding is carried out; 5. leech pond dividing is carried out; 7. water quality management is carried out; and 8. disease preventing and curing management is carried out. The high-density culturing condition of the wide body leeches can be well controlled, observing and managing of the wide body leeches are convenient, leech disease preventing and treatment management is enhanced, the high yield of 500-600 kilograms per acre can be achieved, and the economic benefit of wide body leech artificial culturing is increased.

Description

technical field [0001] The invention relates to the field of leech breeding, in particular to a high-density artificial breeding method for wide-body leeches. Background technique [0002] Leeches, commonly known as leeches, belong to the phylum Annelids, class Hirudophylum, order Hirudidae, and the family Hirudidae. They mainly live in reservoirs, ditches, and lakes in fresh water, and are distributed in the north and south of my country. At present, the varieties cultivated in production include the broad-bodied golden leeches and the philippines. Wide-body golden leech, also known as wide-body leech, wide-body leech, and horse leech, is a mainstream product in the medicinal material market. The whole leech can be used as medicine. For example, the hirudin isolated from the body is an anticoagulant substance, and the leech secretion contains chemical components such as heparin and antithrombotic factor. Therefore, leech has become a valuable medicinal material for the tr...
