Description

A kind of leech catching method

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, and the effect of have broken blood, pursuing the stasis of blood, stimulating the menstrual flow, be mainly used in treating angiocardiopathy and the tumor and cancers such as the clear stasis of blood, amenorrhoea, traumatic injury and apoplexy, hypertension.The leech kind that traditional Chinese medicine is used is mainly eurysome golden thread leech.Propagating artificially of eurysome golden thread leech all obtained initial success at present.Although propagating artificially of leech succeeds, still have a lot of incomplete places.Only leech is fished for this respect, at present the fishing style of leech mainly contain that the cage net is fished for, trawl fishing, night lamp according to fishing for and thick bamboo tube, straw are traped this several modes.Practice shows: thick bamboo tube, straw trapping fishing efficiency is the poorest, there is no practical significance; The cage net is fished for, the trawl fishing leech has certain effect, but a harvesting rate is not high, can not catch at short notice most of leech of breeding water body; Night, lamp was taken a lot of work according to fishing for most, and efficiency is not high yet.The existing way of fishing for all can not have been fished for most of leech of breeding water body at short notice in a word, can not effectively solve the problem of fishing for of leech.

Summary of the invention

The invention provides a kind of leech catching method, avoided existing above-mentioned drawback of fishing for technical approach.For avoiding above-mentioned drawback, the invention provides following technical scheme:

1. first adjust the hirudiniculture pond depth of water, make the water level in hirudiniculture pond be controlled at 0.3-0.5 rice;

2. remove pasture and water and the various floating foreign material in the hirudiniculture waters;

3. the oxygen consumption microorganism of certain solubility of evenly splashing in the hirudiniculture water body;

4. cover the plastic film of one deck black or place the foam kickboard on the water surface of hirudiniculture water body;

5. with artificial pool wall, the plastic film of covering or the leech on the foam kickboard that gathers the surrounding that is adsorbed on breeding water body of little fishing net.

Concrete technical scheme is as follows:

(1) first adjust the hirudiniculture pond depth of water, make the water level in hirudiniculture pond be controlled at 0.3-0.5 rice.The purpose that reduces water level is to save cost in order conveniently to fish for the consumption that operates and reduce the oxygen consumption microorganism of using in next step.

(2) remove pasture and water and the various floating foreign material in the hirudiniculture waters.Do this step work and be mainly after using the oxygen consumption microorganism leech climb to pasture and water etc. above foreign material impact fish for.

(3) evenly splash in the hirudiniculture water body oxygen consumption microorganism of certain solubility.Oxygen consumption microorganism described here refers to one or several in bacillus subtilis, bacillus licheniformis and the saccharomycete of drinking with a guest.Described " the oxygen consumption microorganism of certain solubility of evenly splashing in the hirudiniculture water body " refers to the consumption that decides required oxygen consumption microorganism according to the living bacteria count of used oxygen consumption microorganism, is exactly particularly to make one cubic metre of oxygen consumption microorganism maintenance 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 can not 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) cover the plastic film of one deck black on the water surface of hirudiniculture water body or place the foam kickboard.Plastic film or the foam kickboard of placing black are for shading and accelerate to reduce the oxygen in breeding water body, accelerate leech and up climb out of, and facilitate leech absorption and fish for.

(5) with artificial pool wall, the plastic film of covering or the leech on the foam kickboard that gathers the surrounding that is adsorbed on breeding water body of little fishing net.Splash the oxygen consumption microorganism after 5 hours, leech will gather in a large number and be adsorbed on the breeding water body surrounding pool wall, covering plastic film or above the foam kickboard.Use the concrete effect time of the present invention main relevant with hirudiniculture pond water temperature, instant effect when water temperature is high, temperature is low to take effect slowly.Use when of the present invention, the General Requirements water temperature is not less than 15 degree for well.

Beneficial effect: compare with the existing leech technology of fishing for, adopt technology of the present invention to fish for leech, can disposablely fish for the most of leech in breeding water body; Reduce labour intensity; Reduce and fish for cost; Catching rate and fanning economics have greatly been improved.
