Problems solved by technology

This artificial propagation method has the following problems and disadvantages: the one is that the pro-leech will escape from the source during the breeding period, consumes physical strength, the cocoon production rate is low, the recovery rate of the pro-leech and the collection rate of the cocoon are low; the second is that the pro-leech enters the mud in the cocoon bed Deep, cocoon harvesting is labor-

Embodiment 1

[0053] The present embodiment provides a method for efficiently breeding wide-body golden leeches in cages in plastic greenhouses, and the specific steps are as follows:

[0054] Step 1: Cage Facilities

[0055] (1) Cage production

[0056] ① select 60 mesh sieve tulle to make 100 cages;

[0057] ② Cage specifications

[0058] Be long 2m, wide 1m, high 40cm does not have cover cuboid, and box mouth makes a wide 15cm " ﹃ " shape anti-escape eaves to the inside of the box, and the plane on the net cage is open shape. The mouth of the box is made a "﹃" shape anti-escape eaves with a width of 15cm to the inside of the box, which is to set the anti-escape eaves extending to the inside of the box along the box mouth position at the upper end of the box body. It is an integral structure with a width of 15cm.

Abstract

The invention discloses a net cage breeding method for whitmania pigra. The breeding method includes the steps of preparing a net cage facility, installing net cages, preparing a cocoon producing bed, breeding management and collecting and hatching whitmania pigra cocoons. The net cage is reasonable in structural design, good breed is selected, the design method of the breeding process is reasonable, operation is easy and practical, cost is low, the whitmania pigra breeding effect is improved substantially, and economic benefits are substantially increased.

Description

technical field [0001] The invention relates to a high-efficiency breeding method of a wide-body golden leech cage, belonging to the technical field of aquatic animal breeding. Background technique [0002] Medicinal leeches are traditional precious Chinese medicinal materials in my country. Leeches have a long history of being used as medicines. They have been recorded in the famous Chinese medical books "Shen Nong's Materia Medica" and "Compendium of Materia Medica". , can treat hypertension, coronary heart disease and tumors. At present, medicinal leeches are mostly used in the treatment of diseases of the human and cerebrovascular systems, to prevent the occurrence of human and cerebrovascular thrombosis, and to reduce blood viscosity. The prospects for leech farming are very broad. Broad-bodied golden leech Whitmania pigra Whitman is the preferred species for leech farming due to its large size, fast growth and high medicinal value. [0003] The artificial propagati...
