Description
Technical field
The present invention relates to aquatic animal cultivation field, it is related specifically to a kind of miniflow water circulation type grid and cultivates expanded letter gold
The device of line trematodiasiss seed.
Background technology
Eurysome golden thread leech (Whitmania pigra Whitman1884), is commonly called as Hirudo, calls as horseleech, wide body gold thread
Trematodiasiss and wide body Hirudo, are subordinate to Annelida (ANNELIDA), Hirudinea (Hirudinea), true trematodiasiss subclass (Euhirudinea
Lukin, 1956), Arhynchobdellae (Arhynchobdellida Blanchard, 1894), doctor's trematodiasiss shape suborder
(Hirudiniformes Caballero, 1952), Huang Zhi section (Haemopidae Sawyer, 1986), gold thread trematodiasiss belong to
(Whitmania Blanchard, 1888), widely distributed in China, it is the medicinal aquatic animal of the traditional special type of China.Expanded letter gold
It is traditional Chinese medicine expanded letter money trematodiasiss that line trematodiasiss are dried all, and its nature and flavor is salty, bitter, puts down;Slightly poisonous.Return liver warp.Tool removing blood stasis stimulate the menstrual flow, by
Stagnation resolvation function, for blood stasis is through closing, abdominal mass mass in the abdomen, apoplectic hemiplegia, traumatic injury.Its dry products is used as medicine after processing, and has
The effects such as treatment apoplexy, high blood medicine, amenorrhea, traumatic injury.In recent years, uncontrolled to wild Hirudo with environmental pollution and people
Seizure, wild Hirudo resource increasingly depleted, with the deep development of Hirudo medical value, its market demand potential is huge.
Leeches has hundreds of in the world, and the Hirudo species as medical research is also more, but version in 2010《The Chinese people are altogether
With state's pharmacopeia》Being dried of only 3 kinds of the hirudo provincialis recording is all, wherein being most widely used with eurysome golden thread leech, in recent years
Come the Chinese patent medicine with Hirudo as main component such as NIAOXUEKANG KOUFUYE, antithrombotic piece, Huoxuetongmai capsules etc. of China's approval, its
Using Hirudo medical material almost all be from medicinal material market or the place of production purchase come eurysome golden thread leech dry product.
Improve with people's living standard, cardiovascular and cerebrovascular disease has become domestic and international commonly encountered diseases, frequently-occurring disease, therefore, medical material
Market increases year by year to the demand of Hirudo.
Because wild Hirudo resource quantity is limited, development Hirudo artificial cultivation is imperative.At present, main cultural method
It is：Eurysome golden thread leech seed is directly placed in pond, although the method decrease trematodiasiss kind fish for link, have simple to operate
Advantage, but due to reasons such as bait deficiencies in producing, the trematodiasiss Seedling speed of growth and size heterogeneity greatly, simultaneously as culturing pool
In the pool, the harmful organisms such as Procambarus clarkii, Bufo siccuss, Rana nigromaculata are many, and weed survival rate is extremely low, strongly limit the development of this industry.
Content of the invention
The purpose of the present invention cultivates the device and method of eurysome golden thread leech seed in a kind of miniflow water circulation type grid of offer,
Its purpose one is：Eurysome golden thread leech survival rate brings up to more than 60%；Purpose two is：Cultivate the eurysome golden thread leech seed of 2 months
