Description

External hanging mark for fish marking and releasing

Technical Field

The utility model belongs to the field of mark for marking fishes, relates to a releasing external hanging mark, and particularly relates to an external hanging mark for marking and releasing fishes.

Background

Human activities have become a major threat to the structural and functional integrity of the ecosystem of water and are one of the major factors contributing to the rapid decline of the biological diversity and resource amount of fish worldwide. Fish proliferation and releasing are proved to be an effective way for protecting and recovering fish resources. In order to quickly distinguish whether the captured fish is an individual for proliferation and releasing and further accurately evaluate the proliferation and releasing effect, reliable marking is generally selected for the released individual. At present, the traditional release scale used is large in size, on one hand, the release scale is easy to fall off, the release individual information is not easy to mark relatively completely, on the other hand, damage can be caused to the fish body, and therefore the objective evaluation of the release effect is influenced. Therefore, an external tag for fish marking and releasing, which has small volume, can enhance the stability of the releasing tag and is adjustable in length, is needed.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems in the prior art, the utility model provides the external tag for fish marking and releasing, which has the advantages of small volume, enhanced stability of the releasing tag and adjustable length.

In order to achieve the purpose, the utility model adopts the following technical scheme:

an external tag for fish marking and releasing is characterized in that: the external hanging mark for fish marking releasing comprises a forward mark and a reverse mark buckled with the forward mark.

Preferably, the forward and reverse targets used in the present invention are identical in structure.

Preferably, the positive indicia employed in the present invention comprises a signboard; the end part of the signboard is provided with a plug and a clamping groove; the inner shape of the clamping groove is matched with the shape of the plug; the plug of the forward marker is buckled with the clamping groove of the reverse marker; the plug of the reverse direction mark is buckled with the clamping groove of the forward direction mark.

Preferably, the forward marker and/or the reverse marker adopted by the utility model further comprises a telescopic rod connected with the signboard.

Preferably, the axial direction of the telescopic rod adopted by the utility model is coincident with the axial direction of the signboard.

Preferably, the identification plate adopted by the utility model is sleeved outside the telescopic rod; the telescopic rod extends out or retracts along the axial direction of the signboard.

Preferably, the extension direction of the telescopic rod adopted by the utility model is opposite to the outward extension direction of the plug.

Preferably, the inside of the signboard adopted by the utility model is provided with a shaft step along the axial direction of the signboard; the whole telescopic link is T type.

The utility model has the advantages that:

the utility model provides an external hanging label for fish marking and releasing, which comprises a forward label and a reverse label buckled with the forward label, wherein the forward label and the reverse label have the same structure, and when the external hanging label is used, the forward label and the reverse label are buckled with each other and are used simultaneously. In addition, the forward sign and/or the reverse sign are/is also provided with a telescopic rod connected with the signboard, the telescopic rod can realize the telescopic effect so as to shorten the length of the device, and the telescopic rod can be filled with released fish information, such as the type, age and contact of fish. The signboard fills out the information of releasing fish, such as the type, age and contact person, on the outer edge of the telescopic rod. The draw-in groove is located the inside of signboard, and the plug can insert in the draw-in groove, and draw-in groove and plug that mark forward and reverse can insert each other promptly to strengthen stability. Compared with the traditional drainage buoy, the device is provided with two plugs, so that the stability of the drainage buoy is improved, and the risk that the drainage buoy falls off from the fish body is avoided. The external hanging label for fish marking and releasing provided by the utility model reduces the volume of the traditional releasing label, and the telescopic rod can retract into the signboard, so that the external hanging label is more practical and has great popularization value compared with the traditional releasing label.

Detailed Description

The utility model is further explained below by means of examples in connection with the attached drawings, without limiting the scope of protection of the utility model in any way by the examples.

Referring to fig. 1, 2 and 3, the utility model provides an external label for fish marked releasing, which comprises a forward label and a reverse label buckled with the forward label, wherein the forward label and the reverse label have the same structure. Taking the forward label as an example, the forward label comprises a signboard 2; the end part of the signboard 2 is provided with a plug 4 and a clamping groove 3; the inner shape of the clamping groove 3 is matched with the shape of the plug 4; the plug 4 of the forward mark is buckled with the slot 3 of the reverse mark; the reverse target plug 4 is buckled with the forward target clamping groove 3.

The forward sign and/or the reverse sign also comprises a telescopic rod 1 connected with the signboard 2.

The telescopic rod 1 can be stretched to shorten the length of the telescopic fish-type fish releasing device, and released fish information such as the type, age and contact persons of fish can be filled in the telescopic rod 1. The signboard 2 fills out the information of releasing fish, such as the type, age and contact person of fish, on the outer edge of the telescopic rod. The draw-in groove 3 is located the inside of signboard, and plug 4 can insert in the draw-in groove, and the draw-in groove and the plug of positive sign and reverse sign can insert each other promptly to strengthen stability. This device is fixed on the dorsal fin of releasing fish, compares in traditional release flow mark, and this device is equipped with two plugs, has increaseed release flow mark's stability, has avoided release flow mark from the risk that the fish drops on one's body.

As the preferred scheme, the axial direction of the telescopic rod 1 adopted by the utility model is coincided with the axial direction of the signboard 2, and the signboard 2 is sleeved outside the telescopic rod 1; the telescopic rod 1 extends or retracts along the axial direction of the signboard 2. The extension direction of the telescopic rod 1 is opposite to the outward extension direction of the plug 4. In order to avoid the telescopic rod 1 from falling off from the signboard 2, the utility model is provided with a shaft step inside the signboard 2 along the axial direction of the signboard 2; the telescopic rod 1 is integrally T-shaped, and when the telescopic rod 1 is drawn out from the signboard 2, the telescopic rod is directly clamped on the shaft step.
