Abstract
The invention provides a leech catching method. According to the technical scheme, the leech catching method comprises the following steps of 1, adjusting the water depth of a leech cultivation pool so that the water level of the leech cultivation pool is controlled at 0.3-0.5 meters; 2, clearing away the float grass and different floating sundries in a leech cultivation water area; 3, uniformly splashing oxygen consumption microbes with a certain solubility in a leech cultivation water body; 4, covering a layer of black plastic film or placing a foam floating plate on the water surface of the leech cultivation water body; and 5, manually collecting leeches which are adsorbed on the pool walls of the periphery of the cultivation water body, the covered plastic film or the foam floating plate by utilizing a microcheiria brail. Through adopting the leech catching method provided by the invention, most of the leeches in the cultivation water body can be caught once, thus the leech catching efficiency is greatly improved, the cost of catching is reduced, and the cultivation economic benefits are improved.
Description
Technical field
The present invention relates to a kind of leech catching method, belong to special economic animal cultivation field.
Background technology
Leech is commonly called as leech, is the general designation of Annelida Hirudinea animal.Leech is the traditional traditional Chinese medicine of China, has broken blood, by the stasis of blood, the effect of stimulating the menstrual flow, is mainly used in treating the clear stasis of blood, amenorrhoea, traumatic injury and the angiocardiopathy such as apoplexy, hypertension and tumor and cancer.The leech kind mainly eurysome golden thread leech that traditional Chinese medicine uses.Propagating artificially of current eurysome golden thread leech obtains initial success all.Although propagating artificially of leech succeeds, still have a lot of incomplete place.Only leech fishes for this respect, the fishing style of current leech mainly contains that cage net is fished for, trawl fishing, night lamp according to fish for and this several mode traped by thick bamboo tube, straw.Practice shows: thick bamboo tube, straw trapping fishing efficiency is the poorest, does not have practical significance; Cage net is fished for, trawl fishing leech has certain effect, but a harvesting rate is not high, can not catch most of leech of breeding water body at short notice; Night, lamp was taken a lot of work according to fishing for most, and efficiency is not high yet.Existingly in a word fish for most of leech that way all can not fish for breeding water body at short notice, what effectively can not solve leech fishes for problem.
Summary of the invention
The invention provides a kind of leech catching method, avoid the above-mentioned drawback of existing Fishing technology mode.For avoiding above-mentioned drawback, the invention provides following technical scheme:
1. first adjust the hirudiniculture pond depth of water, make the water lev el control in hirudiniculture pond at 0.3-0.5 rice;
2. remove the pasture and water in hirudiniculture waters and various floating foreign material;
3. the oxygen consumption microorganism of certain solubility of evenly splashing in hirudiniculture water body;
4. on the water surface of hirudiniculture water body, cover the plastic film of one deck black or place foam kickboard;
5. the leech in the pool wall of the surrounding being adsorbed on breeding water body, the plastic film of covering or foam kickboard is manually gathered with little fishing net.
Concrete technical scheme is as follows:
(1) first adjust the hirudiniculture pond depth of water, make the water lev el control in hirudiniculture pond at 0.3-0.5 rice.Reducing the object of water level is conveniently fish for operate and namely the consumption reducing the oxygen consumption microorganism of using in next step saves cost.
(2) pasture and water in hirudiniculture waters and various floating foreign material are removed.Do this step work mainly to fish in order to avoid leech after using oxygen consumption microorganism climbs to impact above the foreign material such as pasture and water.
(3) the oxygen consumption microorganism of certain solubility of evenly splashing in hirudiniculture water body.Oxygen consumption microorganism described here refer to bacillus subtilis, bacillus licheniformis and drink with a guest in saccharomycete one or several.Described " the oxygen consumption microorganism of certain solubility of evenly splashing in hirudiniculture water body " refers to the consumption deciding required oxygen consumption microorganism according to the living bacteria count of used oxygen consumption microorganism, is exactly specifically to make oxygen consumption microorganism keep one cubic metre to fish for oxygen consumption microorganism live bacteria quantity in water body to be not less than 30,000,000,000 viable bacterias.Three kinds of oxygen consumption microorganisms described here all belong to the biologic product of environment-protecting asepsis, be widely used in waste water control, use these three kinds of biologic products to endanger leech, also can not affect surviving and as the effect of traditional Chinese medicine, more can not polluting leech breeding water body environment of leech.
(4) on the water surface of hirudiniculture water body, cover the plastic film of one deck black or place foam kickboard.Plastic film or the foam kickboard of placing black are in order to shading is also accelerated to reduce the oxygen in breeding water body, accelerate leech and up climb out of, facilitate leech adsorb and fish for.
(5) leech in the pool wall of the surrounding being adsorbed on breeding water body, the plastic film of covering or foam kickboard is manually gathered with little fishing net.Splash oxygen consumption microorganism after 5 hours, and leech will gather in a large number and be adsorbed on above the pool wall of breeding water body surrounding, the plastic film of covering or foam kickboard.Use concrete Effect time of the present invention main relevant with hirudiniculture pond water temperature, instant effect during water temperature height, temperature is low, takes effect slow.When using of the present invention, General Requirements water temperature is not less than 15 degree as well.
Beneficial effect: compare with existing leech Fishing technology, adopts technology of the present invention to fish for leech, disposablely can fish for the most of leech in breeding water body; Reduce labour intensity; Reduce and fish for cost; Drastically increase catching rate and fanning economics.
Embodiment
According to following embodiment, the present invention may be better understood, but example only for illustration of the present invention, and should can not limit the present invention described in detail in claims yet.
Example 1 carries out leech and fishes in the pond of lake Area leech.
In the washing basin of the lake Area leech of an area 500 square metres, carry out leech fish for.The net of this lake Area pattern encloses and is arranged in from the water of 1 meter, pond bank.First reduce pond water to 0.5 meter, then by the pasture and water such as the weter hyacinth in pond and floating various eliminating impurities clean, be then the solid pharmaceutical preparation 375 grams of 20,000,000,000 active bacillus subtilises by every gram of effective content, full pool spilling head after being watered 15 kilograms.Then on the water surface of hirudiniculture water body, cover the plastic film of one deck black.After 5 hours, leech will float in a large number and above the purse seine being adsorbed on the water surface and plastic film, now manually sweep leech gently with fishing net.
