Description
Technical field
The present invention relates to a kind of leech adheres to bed, belong to technical field of aquaculture.
Background technology
Leech, popular name leech belong to Annelida, Hirudinea, Gnathobdellida, Hirudinidae animal.It is raw in the freshwater of inland
Long breeding, is the traditional extraordinary medicinal aquatic animal of China, and leech contains hirudin, can delay and hinder blood clotting, so as to
There is blood coagulation resisting function.The hirudin extracted in leech is non-for expansion of blood vessels, reduction blood viscosity, increase blood circulation effect
Chang Xianzhu, now has been developed over treating medicine and various health products, the cosmetics such as apoplexy, hypertension, the clear stasis of blood, amenorrhoea, traumatic injury
Product.
Leech is referred to as " soft gold ", and subject matter is that cultivation survival rate is low, cultured output is relatively low.During propagating artificially
It was found that leech easily suffers from enteritis disease, hemorrhage, mummification, while Jing often occurs, and individuality is uneven, the speed of growth is slow
Problem, causes cultured output relatively low, and survival rate is not high.Jing studies for a long period of time discovery, and leech likes absorption in the water surface and sky after ingesting
The interface of gas, i.e., head-up tail sucker body after some objects are fixed at the bottom does undulating vibratory down or end to end.Its master
Act on relevant with leech digestion, leech digestive system is not, in a tubular form but in tree-shaped, have many in main alimentary canal both sides
The digestion tissue of cryptomere, digestive organs do not have other obvious cyclic motions of animal sample or swing etc. to push the motion of food, because
After this food is absorbed with nutriment in enteron aisle, residue is difficult nature and is pushed to anus.The postdigestive residue of leech
The power resources of anus are moved in two ways：One is gravity, leech mouth upward tail down, swill under gravity
Gradually fall, be transported at anus；Two are pushed food backward by undulating vibratory.Jing ordinary waters leech is by first kind of way
Shifting swill can be more effectively arranged when being combined with the second way.So it is observed that being intended to absorption after leech ingests in pond

The surface area that suitable leech perches is less, therefore unit area leech density is higher, and Chang Kejian flocks together phenomenon, while pasture and water cover
Water oxygenation ability, high temperature night easy anoxic can be excessively affected to cause leech dead.Some bottom of pond leech due to dissolved oxygen
It is relatively low, easily by pathogen infection, suffer from various diseases.When leech lacks attachment base, digestion rate can slow down simultaneously, so as to shadow
Growth is rung, food long-time stops in vivo and is also easy to infect disease of digestive tract.Therefore increase in leech pond and be adapted to leech suction
Attached device is the effective ways for improving the speed of growth, reducing disease, improve yield.
