Problems solved by technology

At present, the species of leech farming is mainly leeches wide-bodied, and the breeding method is mainly pond culture. Due to the lack of systematic and in-depth understanding of the biology, ecological habits and breeding techniques of leech wide-bodied, most farms are unable to make ends meet. loss

Embodiment 1

[0025] Embodiment 1: a kind of method for living water net cage cultivation wide-body golden leeches, the method comprises the steps:

[0026] (1) Make the net cage; the structure of the net cage is as follows figure 1 As shown, the manufacturing method of the net cage is as follows: a semi-open rectangular parallelepiped net cage box body 1 of 8 meters × 3 meters × 1.15 meters is made by adopting 60 meshes of polyethylene and non-nodular mesh, and 8 meters × 1.15 meters are used. 3 meters × 0.85 meters of steel frame is made into box frame 2; the fixed position of box body mesh 1 and box body frame 2 is at 50cm upwards from the bottom of the box body; foam plastic floats are fixed on the four sides of the box body top; The upper outline of the body 1 is straightened with a nylon mesh outline with a diameter of 3 mm; the 1 corner of the box body is tightened with No. 10 iron wire, and the upper part of the net cage box body 1 is 15 centimeters above the water surface; and the ...

Embodiment 2

[0032] Embodiment 2: It is basically the same as Embodiment 1, the difference is: in step (3), insecticide and sterilization are carried out before the aquatic plants are put into the net cage, so as to avoid bringing parasites or pathogens into the net cage.

Embodiment 3

[0033] Embodiment 3: It is basically the same as Embodiment 1, except that in step (4), the leech with wide body mainly uses snails, river clams, etc. as bait. The snails are disinfected and put in together with aquatic plants. The breeding period of the snail coincides with the breeding period of the broad-bodied golden leech, and the small wide-bodied golden leech can eat small snails. It is not advisable to put in too many snails, so as not to compete with leeches for space; the dead snails floating on the water and the snail shells at the bottom should be cleaned up in time; a suspended bait table can also be used to put bait.

Abstract

The invention discloses a method for utilizing running water net cages to breed whitmania pigra. The method includes the following steps that (1) the net cages are manufactured; (2) the net cages are placed at the sheltered and sunny positions in a water area, and the interval between every two adjacent net cages ranges from 2m to 3m; (3) the net cages are placed into water 10 days before the whitmania pigra is placed into the net cages, meanwhile, water hyacinth, lemna minor and other aquatic plants are placed into the cages, and the placed aquatic plants account for 35-40% of the net cage water surface area; (4) food of the whitmania pigra is placed in the water area, wherein the weight of food is 2-3 times the weight of the whitmania pigra; (5) in an appropriate cloudy day early in July, the young whitmania pigra is placed into the different net cages of a river channel according to the body sizes, and the 3000 whitmania pigra is placed in each net cage; (6) in general, nets are hauled and the whitmania pigra is caught from late October. Due to the adoption of the method, the defects that artificial running water breeding cost is high, the yield of the whitmania pigra bred in natural running water surfaces is low, and the whitmania pigra is not easy to catch can be well overcome. The practice shows that due to the adoption of the method, the yield can be effectively improved and social benefits and economic benefits are remarkable.

Description

technical field [0001] The invention discloses a method for cultivating wide-bodied golden leech in live water net cages. Background technique [0002] Wide-bodied golden leeches (Whitmania pigra Whitman 1884), aliased as horse leeches, wide-bodied golden leeches and wide-bodied leeches, belong to the phylum ANNELIDA, class Hirudinea, subclass Euhirudinea Lukin, 1956 ), Arhynchobdellida Blanchard, 1894, Hirudiniformes Caballero, 1952, Haempidae Sawyer, 1986, Whitmania Blanchard, 1888, widely distributed in my country. The whole body of dried leech is a traditional Chinese medicinal material, which is salty, bitter, mild in nature and slightly poisonous. Return liver channel. Tool breaks blood to stimulate menstruation, removes blood stasis and eliminates symptoms, and is used for amenorrhea due to blood stasis, abdominal mass in the abdomen, hemiplegia due to apoplexy, traumatic injuries. In recent years, due to the increase of the clinical demand of leeches wide-bodied, a...
