Description
Technical field
A kind of method of running water cage culture eurysome golden thread leech.
Background technology
Eurysome golden thread leech (Whitmania pigra Whitman 1884), another name is horseleech, wide body gold thread leech and wide body leech, be subordinate to Annelida (ANNELIDA), Hirudinea (Hirudinea), true leech subclass (Euhirudinea Lukin, 1956), Arhynchobdellae (Arhynchobdellida Blanchard, 1894), doctor leech shape suborder (Hirudiniformes Caballero, 1952), Huang Zhi section (Haemopidae Sawyer, 1986), gold thread leech belongs to (Whitmania Blanchard, 1888), extensively distribute in China.The dry entirety of eurysome golden thread leech is traditional Chinese medicine material eurysome golden thread leech, and its nature and flavor are salty, bitter, flat; Slightly poisonous.Return Liver Channel.Tool breaks blood and stimulates the menstrual flow, Zhu Yu Xiao Disorder function, for blood stasis through Bi ， Disorder lump in the abdomen lump in the abdomen, and hemiplegia, traumatic injury.In recent years, due to the increase of the clinical demand of eurysome golden thread leech, simultaneously due to the environmental pollution of natural water area, its habitat constantly reduces, and cause its population quantity to reduce, wild resource is day by day exhausted, so propagating artificially of development eurysome golden thread leech is imperative.This measure can not only meet clinical and needs that are scientific research, also becomes a kind of efficient aquaculture, has positive effect to growth of agricultural efficiency, increasing peasant income.
Jiangsu is as one of the major production areas of eurysome golden thread leech, and most important reason is water surface aboundresources, and many regional networks of rivers are intensive, river course intersects, reservoir spreads all over the place, water quality is good, and water body flow is strong, is referred to as " running water ", bait is sufficient simultaneously, the growth of very suitable eurysome golden thread leech.The kind of current hirudiniculture is mainly eurysome golden thread leech, and breeding way is pond culture mainly, owing to lacking the understanding in depth of system to eurysome golden thread leech biology, ecological habit and cultural technique, causes the unable to make ends meet and losses due to poor management of most of plant.
Summary of the invention
For the above-mentioned defect of prior art, the technical problem to be solved in the present invention is to provide a kind of can reduce artificial flowing water culture cost, improve the method for nature running water water surface aquaculture eurysome golden thread leech output, suitable running water cage culture eurysome golden thread leech of fishing for.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A method for running water cage culture eurysome golden thread leech, the method comprises the steps:
(1) net cage is made;
(2) net cage is positioned over hidding and sunny side place, waters, interval 2-3 rice between adjacent two net cages;
(3) net cage 10 all over the world water before eurysome golden thread leech cartonning, in the mesh sheet being conducive to net cage, the attachment such as attached algae, can effectively avoid eurysome golden thread leech to rub injured; Abort in case the water plants such as cucurbit, duckweed simultaneously, and injected volume is the 35-40% of the net cage water surface;
(4) food of eurysome golden thread leech is thrown in by 2 ~ 3 times of eurysome golden thread leech weight;
(5) select the suitable cloudy day, by young leech by body size, put into the different net cage in river course respectively, each net cage throws in 3000 in the first tenday period of a month in July;
(6) in the ordinary course of things, the last ten-days period in October, hauling was fished for.
In step (1), the preparation method of described net cage is: adopt mesh 60 object polyethylene, make the semi-open-type cuboid net cage body of 8 meters × 3 meters × 1.15 meters without tubercle mesh sheet, adopt the steel bar framework of 8 meters × 3 meters × 0.85 meter to make tank tower; The position that casing mesh sheet and box frame are fixed is at bottom half upwards 50cm place; Four limits at casing top are fixed with floater of foam; The nylon head rope of the exaggerated diameter of described casing 3 millimeters is stretching; No. 10 iron wires in casing angle are strained, and described net cage body top is exceeded the water surface 15 centimetres; And described net cage body exceeds the infolding that water surface part arranges 15cm, drives piles under water with mao bamboon, stake is slip-knot, is convenient to net cage following water-level lifting.
In step (3), enter net cage advance row pesticide-germicide water plants, avoid a parasite or pathogene to bring in net cage.
In step (4), described eurysome golden thread leech mainly with river snail, Corbicula fluminea etc. for bait.
Preferably, described river snail etc. are sterilized input together with pasture and water.River snail breeding period and eurysome golden thread leech match breeding period, and little eurysome golden thread leech can have little river snail.Throw in river snail too much unsuitable, in order to avoid fight for space with leech; The river snail that dead floats on the surface and the river-snail sheil sunk to the bottom will be cleared up in time; Also suspension bait table can be selected to throw in bait.
Beneficial effect of the present invention is: adopt the present invention can solve artificial flowing water culture cost very high, natural running water water surface aquaculture eurysome golden thread leech well and yield poorly, the shortcoming such as should not to fish for.Practice shows to adopt this cultivation effectively can improve output, and economic results in society are remarkable, specific as follows:
(1) expense of excavation pond for cultivation can be saved, ecotope is not damaged.Invest little, the totle drilling cost of a net cage is 335 yuan, wherein framework of steel reinforcement cost 130 yuan, floater of foam 75 yuan; Instant effect, later stage breeding cycle just can be fished at four months; High efficiency, a net cage can manufacture a finished product fresh eurysome golden thread leech 9 kilograms, calculates, the results of a net cage 7200 yuan by market price 800 yuan of per kilograms.Deduction direct cost can income 6365 yuan.Investment instant effect, breeding facility utilizes the cycle long, can utilize 6-7.
(2) make full use of caged-culture waters and erbium material food, survival rate is high, and the price of deed is high.Social and economic benefits is remarkable.
(3) short, the convenient management of breeding cycle, there is maneuverability, advantage easy and simple to handle.Net cage can change at any time according to the change of water environment condition.Meet flood, " water rise net height "; Meet drought, " water fall net low "; Can high yields irrespective of drought or water logging be realized, reach the object of stable high yield.
(4) harvesting is easy.Do not need during results to fish for instrument especially, can once go on the market; Also can according to market demand, harvesting by stages and in groups, is conducive to market regulation.
(5) strong adaptability, is convenient to promote.Not only be applicable to river course, all applicable for reservoir, lake.
