Problems solved by technology

As a new industry in modern agriculture, medicinal leech breeding is not difficult to feed, but the survival rate of breeding is low, and high-density breeding cannot be carried out.
At present, the conventional mode of breeding leeches is intensive cultivation in cement ponds, which has the problems of troublesome construction and cumbersome maintenance of the breeding ponds.

Embodiment 1

[0016] A method for cultivating leeches at a high density with mulching film, comprising the steps of:

[0017] Step 1. Build a breeding pond: Choose a place that is convenient for drainage and irrigation and build a pond in a rectangular, square or circular shape. The ponds can accommodate people. The bottom and walls of the ponds are covered with plastic film, which eliminates the need for cement pouring. The construction is simple and the investment is small. . Nylon nets are buried around the pool to prevent the natural enemies of leeches, i.e. frogs and snakes, from entering, so that leeches have a safe growth environment. Two opposite pool walls of the culture pond are obliquely oppositely provided with a water inlet and a water outlet. The water inlet is high and the water outlet is low. , not only to avoid blockage of the water outlet but also to prevent leeches from escaping from the water outlet.

[0018] Step 2, building a breeding environment: Pebbles and aquatic...

Embodiment 2

[0023] The difference between this example and Example 1 lies in that: the floating-leaf plant is water phoenix or water poppy, and the submerged plant is foxtail algae or hornwort. Purify water quality and increase dissolved oxygen in water.

Embodiment 3

[0025] The difference between this example and Example 1 is that in order to prevent leech disease, when building a breeding environment, adding probiotic liquid to the breeding pond can purify water quality, inhibit and phagocytose pathogenic bacteria, adjust the balance of microorganisms in the water body, activate And enhance the immune function of leeches.

Abstract

The invention discloses a mulching film type high-density leech breeding method. The method comprises the following steps of breeding pond building, breeding environment construction, species throwing, bait throwing and daily management. The constructed breeding environment and snails in bait form ecological circulation, the growing environment of leeches in a breeding pond can be maintained in later period conveniently, the leeches can be subjected to high-density, high-yield and high-quality breeding through the five steps, and the survival rate of the leeches is greatly increased. Accordingto the mulching film type high-density leech breeding method, the method has the advantages of being high in unit area survival rate, easy to construct and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating leeches in a plastic film type with high density. Background technique [0002] Leeches, commonly known as leeches and horse turtles, belong to the phylum Annelids, class Hirudophylum, order Hirudidae, and family Hirudoceae. They grow and reproduce in inland freshwater waters. They are traditional special medicinal aquatic animals in my country. Hinder blood coagulation, thus have anticoagulant effect. Its dry products are processed and used as medicine in traditional Chinese medicine, which has the effects of treating stroke, high blood pressure, clearing blood stasis, amenorrhea, and traumatic injuries. As a new industry of modern agriculture, medicinal leech breeding is not difficult to raise, but the survival rate of breeding is low, and high-density breeding cannot be carried out. At present, the conventional mode of culturing leeches is intensi...
