Embodiment 1

[0034] The schematic diagram of the feeding device is shown in figure 1 . Among them: 1 is a bracket, 11 is a side door, 12 is a support ring, 13 is a hinge, 2 is a nylon mesh, and 3 is a clip.

[0035] The radial length of the stent is 0.5m, and the side length of the bottom surface is 12cm. The aperture of the nylon mesh is 1cm (the aperture is variable, depending on the size of the snail, generally 1-2cm).

[0036] The hinge 13 can optionally be a hinged hinge.

[0037] Part of the feeding device is shown in figure 2 .

[0038] Add the more active snails to the feeding device, and fix the door with clips. Sink the feeding equipment into the wide-bodied leech breeding tank, either on the side or in the middle (ideally on the side). After the snails are fed, the feeding situation of the leeches can be observed. After being sucked, the snails mostly sink to the bottom of the device. Observe the feeding situation and replenish the snails in time and clean up the snails a...

Embodiment 2

[0040] The schematic diagram of the feeding device is shown in image 3 . Among them: 1 is the bracket, 11 is the bottom door, 12 is the support ring, 13 is the hinge, 2 is the barbed wire, and 3 is the clip.

[0041] The radial length of the stent is 1.2m, and the side length of the bottom surface is 30cm. The aperture of the wire mesh is 1.1cm (the aperture is variable, depending on the size of the snail, generally 1-2cm).

[0042] The hinge 13 can optionally be a hinged hinge.

[0043] Add the more active snails to the feeding device, and fix the door with clips. Sink the feeding equipment into the wide-bodied leech breeding tank, either on the side or in the middle (ideally on the side). After the snails are fed, the feeding situation of the leeches can be observed. After being sucked, the snails mostly sink to the bottom of the device. Observe the feeding situation and replenish the snails in time and clean up the snails after being sucked.

Embodiment 3

[0045] The schematic diagram of the feeding device is shown in figure 1 . Among them: 1 is a bracket, 11 is a side door, 12 is a support ring, 13 is a hinge, 2 is a plastic mesh, and 3 is a clip.

[0046] The radial length of the stent is 1.5m, and the side length of the bottom surface is 35cm. The aperture of the plastic mesh is 1.2cm (the aperture is variable, depending on the size of the snail, generally 1-2cm).

[0047] The hinge 13 can optionally be a hinged hinge.

Abstract

The invention belongs to the field of cultivation and particularly relates to a whitmania pigra feeding method The whitmania pigra feeding method comprises the following steps of 1) adding snails intoa feeding device, and sinking the feeding device into a whitmania pigra breeding pond; 2) observing the feeding status of whitmania pigra, timely replenishing snails and cleaning the snails sinking down to the bottom of the feeding device. The support of the feeding device is an iron support in a columnar or cuboid shape, the support is provided with a door, and the outer surface of the feeding device is covered by a net with a pore diameter of 1-2 cm. The whitmania pigra is originally fed in a splashing mode, which is prone to resulting in injury and infection of the snails, and dead snailscan pollute water and are difficult to fish; the feeding mode applied in the whitmania pigra feeding method can effectively reduce diseased snails, ensure water cleanliness and save labor, and workerscan replenish or clean the snails according to the feeding status of the whitmania pigra.

Description

technical field [0001] The invention belongs to the field of breeding, and in particular relates to a feeding method of wide-bodied leech. Background technique [0002] Wide-body golden thread leech is a variety of leech with high medicinal value. It is mainly used to extract natural hirudin with anticoagulant and thrombolytic effects. Broad-bodied leech bodies are long, flat, and slightly fusiform. The adult leech is 6-13 cm long and 1.3-2 cm wide, and the large body is up to 3.5 cm wide. The back is usually dark green with 5 vertical stripes formed by alternating yellow and black markings. There is a yellow vertical band at the lower end of the side. The abdomen is pale yellow with many irregular dark green spots. [0003] When the wide-bodied leech is artificially cultured, it mainly sucks the body fluids of aquatic animals such as snails and river mussels. The original feeding method of the wide-bodied golden thread leech is the splashing method. The fishing of sna...
