Abstract
The utility model discloses a parent prawn artificial mating fixing device for a prawn with a closed seminal receptacle. The parent prawn artificial mating fixing device comprises a board and a parent prawn fixing piece which is fixed to the board through nails. The parent prawn fixing piece is composed of a circular pipe and a C-shaped strip sheet-shaped structural part, wherein the circular pipe is used for accommodating the tail of the parent prawn, the C-shaped strip sheet-shaped structural part is located beside the circular pipe and used for placing the parent prawn in the mode that the abdomen of the parent prawn is upward, and an opening of the C-shaped strip sheet-shaped structural part is upward. The parent prawn fixing device is simple in structure and can effectively fix the parent prawn and make the parent prawn be in a stable and comfortable state. According to the parent prawn fixing device, the requirement for manpower in the process of prawn artificial mating can be reduced, and the parent prawn fixing device can be operated by one person; the parent prawn can be prevented from jumping to the maximum, and the possibility that the seminal receptacle of the parent prawn is damaged by forceps is reduced to the minimum; the phenomenon that an embedded spermatophore falls off due to jump of the parent prawn can be prevented.
Description
Technical field
The utility model belongs to technical field of aquaculture, relates to specifically a kind of artificial cross parent shrimp fixture be used to closed receptaculum seminis prawn is arranged.
Background technology
Prawn has special genital system and reproductive behavio(u)r, and the female receptaculum seminis of prawn has two kinds of forms, and a kind of is open receptaculum seminis, and another kind is enclosed receptaculum seminis.Male shrimp is just inputted spermatophore in the receptaculum seminis of female shrimp before female shrimp lays eggs, and discharges sperm when it is laid eggs, and this fertilization mode has been brought very large difficulty to the directive breeding of prawn.Common prawn spermatophore implantation technique is for the prawn with closed receptaculum seminis: a staff is worn cotton gloves, encases the shrimp body with wet towel, only reserves receptaculum seminis.Another person lives spermatophore or the vas deferens of male shrimp with elbow ophthalmic tweezers sub-folder, insert along the Y suture in the middle of receptaculum seminis, and spermatophore or vas deferens are put into receptaculum seminis.
Prawn spermatophore implantation technique shortcoming of the prior art has three: the one, and operating process needs two people to coordinate to complete, and people is shrimp fixedly, and another person carries out artificial insemination; The 2nd, can not well fix close shrimp in operating process, close shrimp very easily jumps, and this probability that just makes tweezers hurt close shrimp increases greatly, also has operating process easily firmly to oppress the gill and the heart of close shrimp; The 3rd, the spermatophore of implanting easily causes spermatophore to come off because close shrimp jumps.
The utility model content
The deficiency that the utility model exists in order to overcome prior art, a kind of simple in structure, the artificial cross parent shrimp fixture that is used for having closed receptaculum seminis prawn that can effectively fix close shrimp is provided, and this parent shrimp fixture can make close shrimp be in stable and comfortable state.
The utility model is achieved through the following technical solutions: a kind of artificial cross parent shrimp fixture be used to closed receptaculum seminis prawn is arranged, it comprises plank and is fixed in close shrimp fixture on plank by nail, parent's shrimp fixture is placed the rectangular sheet structure of " C " font of close shrimp up and is consisted of, the opening upwards of the rectangular sheet structure of " C " font by the pipe that is used for accommodating close shrimp afterbody and the belly that is used for that is positioned at the pipe side.
Parent shrimp fixture is the PVC structural member, and pipe is the PVC pipe that inner diameter is a bit larger tham close shrimp tail diameter, and pipe is drainpipe or the feed pipe of PVC material, and the PVC pipe can determine according to the size of close shrimp its length and diameter.
close shrimp fixture of the present utility model is comprised of close shrimp fixture and the plank of PVC material, the length and the diameter that are used for the pipe of fixing close shrimp will be decided according to the size of close shrimp, because shell parent shrimp will be put in close shrimp fixture fixing, therefore pvc pipe will be in its 2/3rds places rip cutting, then leading portion 2/3rds wants crosscut to come, but also it to be strutted, the shape of pvc pipe bottom is just " C " font like this, and the back build of close shrimp belly up time this shape of also just coincideing, so close shrimp back more is fitted in the rectangular sheet structure of " C " font, be difficult for beating, so that close shrimp belly up, closed receptaculum seminis exposes outside, be convenient to the spermatophore conveying and complete mating.Rear 1/3rd pvc pipe does not have cross section, the sealing of keeping intact, and the afterbody of so close shrimp just can put in, and can prevent that close shrimp from beating and affecting Process of Insemination and spermatophore comes off.
The beneficial effects of the utility model are: close shrimp fixture of the present utility model is a kind of simple in structure, the artificial cross parent shrimp fixture that is used for having closed receptaculum seminis prawn that can effectively fix close shrimp, and this parent shrimp fixture can make close shrimp be in stable and comfortable state.During use, close shrimp belly is positioned over up on the rectangular sheet structure of " C " font, the afterbody of close shrimp is inserted in pipe, close shrimp head is covered with towel wet from sea water, reserves the receptaculum seminis position in the towel indentation, there, facilitates artificial cross.The effect of plank is balance PVC parent shrimp fixture, and when operation, PVC parent shrimp fixture can not swing, and plank plays a balanced action.Close shrimp fixture of the present utility model has the following advantages: 1, can reduce in the prawn artificial cross to the demand of manpower single can the operation; 2, can prevent to greatest extent that close shrimp from jumping, and makes tweezers be reduced to minimum to the possibility that close shrimp receptaculum seminis damages; 3, can prevent that the spermatophore implanted is because the close shrimp spermatophore that causes that jumps comes off.
Description of drawings
Fig. 1 is the perspective view of the utility model parent shrimp fixture;
In figure: the 1-plank; The 2-nail; The 3-pipe; The rectangular sheet structure of 4-" C " font.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of artificial cross parent shrimp fixture be used to closed receptaculum seminis prawn is arranged, it comprises plank 1 and is fixed in close shrimp fixture on plank 1 by nail 2, parent shrimp fixture is by the pipe 3 that is used for accommodating close shrimp afterbody and rectangular sheet structure 4 formations of " C " font that belly is placed close shrimp up that are used for that are positioned at pipe 3 sides, the opening upwards of the rectangular sheet structure 4 of " C " font, parent shrimp fixture is the PVC structural member, the PVC pipe of pipe 3 close shrimp tail diameter for inner diameter is a bit larger tham.
The preparation method of the utility model parent shrimp fixture is: pvc pipe is entered 1/2nd dark in its 2/3rds places rip cutting, double crosscut come on the pvc pipe of 2/3rds length, then it strutted, and the pvc pipe of 1/3rd length is constant.
Should be noted that at last; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from essence and the scope of technical solutions of the utility model.
