Technical Field
The utility model relates to a float formula leech case of laying eggs, this case of laying eggs specially adapted widescrow gold thread leech, poecilobdella manillensis and the breed of artificial breeding leech varieties such as japanese medicinals leech belong to aquaculture production facility technical field.
Background
The leech is a precious medicinal resource, has multiple medicinal functions in medicine, has the effects of resisting coagulation and breaking blood stasis, is a specific medicine for treating cerebral thrombosis, rheumatism, arthritis and other diseases, is an animal traditional Chinese medicinal material with high development value, particularly after the 21 st century, with the vigorous development of new and Chinese medicinal herbs for treating cardiovascular and cerebrovascular diseases by using leeches as main raw materials by Chinese medical enterprises, the application range of leeches is further widened, the use level of leeches is greatly increased, the original annual demand is increased from several tons to more than 500 tons, however, most of leeches come from wild, natural leech resources are exhausted in successive years, the yield is greatly reduced in successive years, and the leech culture technology has a bottleneck problem, so that the cultured leeches have small yield, the gap between the supply and demand of medicinal leeches is enlarged, and the artificial cultured leeches have huge market potential and wide economic benefit prospect.
The leech breeding is an important step in the leech breeding process, and spawning is a key link in the leech breeding process, at present, the artificial breeding of the leech mainly adopts spawning under natural conditions and facility conditions, the former is greatly influenced by natural environment and accompanied by the invasion of harmful organisms, and the spawning effect of leech parents is difficult to ensure; the latter generally builds a spawning environment with a steel frame greenhouse, which occupies land resources and has a large construction cost, and the capturing and carrying of parents take labor and effort, and have large mechanical damage to the parents.
SUMMERY OF THE UTILITY MODEL
To prior art not enough, for solving above-mentioned at least one technical problem, the utility model provides a float formula leech case of laying eggs, the suitable environment of laying eggs can be built to this case of laying eggs in aquaculture pond, reduces the expenditure of land cost, construction cost and cost of labor etc. and the parent damage that also can reduce simultaneously improves the spawning rate of leech greatly.
The utility model provides a technical scheme of above-mentioned technical problem is:
a floating type leech spawning box comprises a box body, wherein the box body consists of a box cover, a box wall and a bottom plate; the box body is provided with a floater on the lower part outside the box body, the floater enables the box body to float on the water surface, and the whole box body can be controlled to be kept at a proper position according to the water level so as to keep stable humidity in the whole box body and create good habitat conditions for leech spawning. The bottom plate of box is provided with the opening, the opening contacts with the surface of water, and the surface of water is located the bottom plate upper surface below, prevents that the surface of water fluctuation from drenching the matrix of laying eggs in the breed aquatics pond, keeps the humidity of the matrix of laying eggs invariable, provides suitable environment of laying eggs for the leech parent. When the leeches enter the spawning period, the leech parents enter the spawning box from the opening and enter the spawning substrate to spawn, and the leeches return to the culture pond from the opening after the spawning is finished. The base plate outside the opening is provided with a spawning substrate, the spawning substrate is formed by mixing various culture substrates with plant straws, has the characteristics of softness, porosity, moderate hardness, constant humidity and the like, and is beneficial to the drilling in and out of leeches. Above the spawning substrate, a plurality of air holes are formed in the box wall, so that air is provided for a closed spawning space of the box body, and the normal oxygen requirement of the leech parent is guaranteed.
In order to adapt to the biological characteristics that leeches are punched vertically and horizontally, the difficulty of punching and cave-making of the leeches is reduced, and the containing density of the leeches of a spawning substrate is increased, wherein the surface of the spawning substrate is inclined towards an opening, and the inclination angle is 45 degrees.
In order to avoid water from entering the air holes and prevent the air holes from being blocked by the spawning substrate, the air holes are formed in the upper half part of the box wall.
In order to fix the box body, a fixing rope is arranged on the box body. Specifically, fixed ropes are mounted at four corners below the box body. The other end of the fixing rope is connected to the bottom of the culture pond for fixing, so that the stability of the whole box body is improved, and the mechanical damage to the box body caused by severe weather is reduced.
The box body is made of waterproof materials (such as wood, foamed plastic and the like) with low density, so that the buoyancy of the box body can be increased, water leakage is prevented, light is shielded, and invasion of harmful organisms is avoided.
The utility model discloses a case of laying eggs simple structure, reasonable in design, simple operation, low in cost, this float formula leech incubator do not receive the space restriction, do not receive the water level influence, do not receive the invasion and attack of enemy's living beings, have reduced land cost, construction cost and cost of labor, have built the oviferous suitable environment of leech, have ensured the economic benefits of breeding the leech.

Fig. 2 is a top view of the spawning box of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, the floating type leech spawning box comprises a box body 1, and specifically, the box body 1 is composed of a box cover 4, a box wall 5 and a bottom plate 6. The box body 1 is made of foam plastics (or other waterproof materials with low density), buoyancy of the box body 1 is increased, water leakage is prevented, light is shielded, and invasion of harmful organisms is avoided.
In order to fix the box body 1, all install fixed rope 9 on the four corners of box body 1 below, the fixed rope 9 other end is connected to and breeds the pond bottom of the pool and fix, has increased the stability of whole box body 1, reduces the mechanical damage that bad weather brought box body 1.
Outside the box body 1, the floaters 2 are arranged around the lower part of the box body 1, the floaters 2 enable the box body 1 to float on the water surface, the installation height of the floaters 2 on the box body 1 can be determined according to the specific floating height, and the whole box body 1 can be controlled to be kept at a proper position according to the water level so as to keep the stable humidity in the whole box body 1 and create good habitat conditions for the leech to lay eggs.
Be provided with rectangle opening 8 on box 1's the bottom plate 6, opening 8 and surface of water contact, the surface of water is located below the 6 upper surfaces of bottom plate to prevent that the surface of water fluctuation from drenching the matrix 3 of laying eggs in the aquaculture pond, keep the humidity of the matrix 3 of laying eggs invariable, provide suitable oviposition environment for the leech parent. When the leech enters the spawning period, the leech parent enters the spawning box from the opening 8 and enters the spawning substrate 3 to spawn, and the leech parent returns to the culture pond from the opening 8 after the spawning is finished.
The spawning substrate 3 is placed on the bottom plate 6 outside the opening 8, the spawning substrate 3 is formed by mixing various culture substrates with plant straws, has the characteristics of softness, porosity, moderate hardness, constant humidity and the like, and is beneficial to the drilling in and out of leeches. In order to adapt to the biological characteristics that leeches are punched vertically and horizontally, the difficulty of punching and cave-making of the leeches is reduced, and the containing density of the leeches of the spawning substrate 3 is increased, wherein the surface of the spawning substrate 3 is inclined towards the opening 8, and the inclination angle is 45 degrees.
