Description

Ricefield eel oxytocic injection fixer

Technical Field

The utility model belongs to a finless eel breeding tool, in particular to a finless eel induced spawning injection fixer.

Background

The finless eel is an important special economic cultured fish in China, the national statistical yield in 2018 is 31.9 ten thousand tons, and the estimated value of the yield per unit of production exceeds 400 hundred million yuan. The rice field eel is tender and delicious, has high nutritive value, has certain medicated diet nourishing and treating effects, is deeply loved by consumers, has the market sale price kept above 30 yuan/jin all the time, and belongs to high-value famous and excellent aquatic products.

In the existing finless eel breeding industry, 90% of fries are from wild harvested fries, and a small amount of fries are self-used for artificial breeding of the fries. Along with the expansion of the artificial breeding scale of the finless eels, the demand for the fries rises, the total quantity of wild captured fries is in a descending trend year by year, and the price is high due to the lack of quantity. The problems of small quantity, high price and low survival rate of wild finless eel seedlings seriously limit the expansion and sustainable healthy development of finless eel industry. Therefore, the method for solving the bottleneck problem is to enlarge the scale of the indoor large-scale full-artificial induced spawning and breeding of the finless eels, wherein the induced spawning and breeding technology is an important link in the work. In the induced spawning process, oxytocin is injected into the finless eel body in an injection mode. Because the mucus of the female parent of the finless eel is slippery, the finless eel must be fixed by one person in the injection operation, and the other person is used for injection by an injector, so the operation is very inconvenient and the injection efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a rice field eel injection fixer that hastens parturition to solve rice field eel female parent mucus slippery, the injection operation of being not convenient for, the problem of injection inefficiency.

Realize the utility model discloses the technical scheme that the purpose was adopted as follows:

the utility model provides a finless eel injection fixer that hastens parturition, including backing plate, one side and backing plate articulated clamp plate, the intermediate part of clamp plate is for having porous poroid structure.

The pressing plate comprises a frame and a hole-shaped structure fixed in the frame.

The frame is provided with a handle, so that the pressing plate is convenient to operate.

The porous structure comprises one of meshes, round holes, square holes, rectangular holes, polygonal holes and strip-shaped holes.

Advantageous effects

The utility model discloses usable clamp plate is with the rice field eel immobility, utilizes the requirement that poroid structure satisfied the injection, when to the internal oxytocic hormone of injection of rice field eel, but one man operation, and clamp plate is pushed down to one hand, and the other hand is injected. Because the finless eel is fixed through the porous structure, the fixing effect is good, the damage to the female parent is small, and the injection efficiency is high. The utility model discloses can save the manual work.

The technical scheme of the utility model is further explained in the following with the attached drawings.

Detailed Description

Referring to fig. 1-3, the utility model provides a finless eel oxytocic injection fixer, which comprises a backing plate 4 and a pressing plate hinged with the backing plate 4 through a hinge 5, wherein the middle part of the pressing plate is in a porous structure; the clamp plate includes frame 1 of constituteing by upper and lower frame 1a, 1b, and the porous structure is polyethylene net piece 2 for having the mesh, and polyethylene net piece 2 presss from both sides between upper and lower frame 1a, 1b to fix as an organic whole with screw 3, the one side of keeping away from hinge 5 on frame 1 is equipped with handle 6 through screw 3.

The porous structure may be a sheet provided with circular holes, square holes, rectangular holes, polygonal holes, strip-shaped holes, or the like, or a woven structure thereof.

When the utility model is used, oxytocin is injected into the physiological saline bottle according to the proportion, and the physiological saline bottle is inversely hung on the hook of the bracket; inserting a needle head of a medicine inlet pipe of the injector into a 5cm position in a bottleneck of a physiological saline bottle, adjusting injection scales of 0.1-0.3 ml by the injector, and drawing diluted oxytocin from the physiological saline bottle through the medicine inlet pipe and the needle head during each injection; the female ricefield eel parent is placed on the base plate 4, the towel is laid, the handle 6 is held by one hand of an operator, the female ricefield eel parent is lightly pressed by the pressing plate, the grid of the polyethylene net piece 2 on the pressing plate enables the ricefield eel not to easily slide, and the other hand of the operator uses the injector to inject oxytocin to the female ricefield eel parent.
