Description

Technical Field

[0001] This invention relates to the field of fish traceability tagging technology, specifically to a fish anti-shedding traceability tagging device. Background Technology

[0002] Fish tracking and tagging technology is an important tool for studying fish genetics and breeding, as well as evaluating the effectiveness of stock enhancement and release programs. By tagging fish caught in natural waters and releasing them back into the same waters, the information from the tags can be used to study the migration, distribution, growth, and resource status of the fish upon recapture, which is of great significance for the ecological assessment of fish.

[0003] In existing technologies, fish traceability tags are generally implanted into the surface of live fish or worn on their fins. For example, CN107279018B discloses a traceability tag for large yellow croaker. This tag involves penetrating a probe with a radio frequency chip into the tissue below the tail of the large yellow croaker's dorsal fin, with the tag cap in contact with the fish's body surface. A fixing ring is then connected to the threaded head at the tip of the probe to secure the tag to the fish. While this method provides a secure hold, it is quite damaging to the fish. The probe penetrating the fish can cause infection or necrosis of the surrounding tissue at the penetration point, leading to tag detachment and, in severe cases, even death. While wearing the fish traceability tag on the fin can reduce the damage to the fish, the fin is relatively thin, and fish mainly swim using their fins. During the movement of the fins, the traceability tag is easily dislodged. Summary of the Invention

[0004] In view of this, the present invention provides a fish anti-detachment traceability tagging device that can be fixed at three points on the fish's tail fin, increasing stability and reducing the risk of tag detachment.

[0005] A fish anti-detachment traceability tagging device includes a traceability tag installed on the fish's tail fin for recording fish information and auxiliary fixing components. The traceability tag is tightly attached to the fish's tail fin. A first clamping component is provided on the end face of the traceability tag that is attached to the fish's tail fin, penetrating and clamping the fish's tail fin to fix the traceability tag. There are two auxiliary fixing components, symmetrically arranged on the upper and lower sides of the traceability tag. One end of each of the two auxiliary fixing components is pin-connected to the traceability tag or the first clamping component, and the other end extends towards the tip of the fish's tail fin and opens outward. Adjustment grooves are provided on each of the two auxiliary fixing components along their extension direction. Sliding second clamping components are provided on the adjustment grooves of the two auxiliary fixing components. The two second clamping components penetrate and clamp the fish's tail fin, arranged in a triangle with the first clamping component to provide three-point auxiliary fixation for the traceability tag. The two second clamping components can move along the adjustment grooves as the fish's tail fin grows, and drive the auxiliary fixing components to unfold outward along the traceability tag.

[0006] Preferably, the first clamping member includes a first fixing pin and a first clamping seat. The first fixing pin is laterally disposed on the end face of the traceability label that fits with the fish tail fin and penetrates the fish tail fin. The first clamping seat is disposed on the other side of the fish tail fin opposite to the traceability label. The first clamping seat is provided with a first fixing hole for the first fixing pin to pass through. After the first fixing pin passes through the fish tail fin, it is inserted into the first fixing hole and fixed thereto, so that the first clamping seat and the traceability label are clamped to each other on both sides of the fish tail fin.

[0007] Preferably, a first elastic card is provided in the first fixing hole, and the tip of the first fixing pin inserted into the first fixing hole is provided with a first slot. The first elastic card can be locked in the first slot to prevent the first fixing pin from separating from the first fixing hole.

[0008] Preferably, the second clamping member includes a slide, a second fixing pin, and a second clamping seat. The slide is disposed on the adjustment groove and closely adheres to one side of the fish tail fin, and is movable along the adjustment groove. The second fixing pin is disposed laterally on the slide and penetrates the fish tail fin. The second clamping seat is disposed on the other side of the fish tail fin opposite to the slide. The second clamping seat is provided with a second fixing hole for the second fixing pin to pass through. After penetrating the fish tail fin, the second fixing pin is inserted into the second fixing hole and fixed thereto, so that the second clamping seat and the slide clamp each other on both sides of the fish tail fin.

[0009] Preferably, a second elastic card is provided in the second fixing hole, and the tip of the second fixing pin inserted into the second fixing hole is provided with a second slot. The second elastic card can be locked in the second slot to prevent the second fixing pin from separating from the second fixing hole.

[0010] Preferably, the first clamping seat, the traceability label, the second clamping seat, and the slide seat are each provided with a number of flexible protrusions on the end faces that contact the fish tail fin.

[0011] Preferably, a third clamping member is provided on the end face of the traceability tag that is attached to the fish tail fin. The third clamping member and the first clamping member are respectively provided at both ends of the traceability tag, and the third clamping member has the same structure as the first clamping member.

[0012] Preferably, the outer surface of the traceability label is provided with a traceability code containing fish information and a protective film, and the protective film covers the traceability code to protect it.

[0013] Preferably, the traceability label and the two auxiliary fasteners are both flexible plastic sheets with rounded corners.

[0014] Preferably, the traceability label and the two auxiliary fasteners are provided with flexible protective edges around their four edges.

[0015] As can be seen from the above technical solution, the present invention provides a fish anti-detachment traceability tag device installed on the tail fin of a fish. Its advantages over the prior art are: it includes a traceability tag and auxiliary fixing components. The traceability tag is tightly attached to the fish's tail fin. A first clamping component is provided on the end face of the traceability tag that is attached to the fish's tail fin. The first clamping component penetrates and clamps the fish's tail fin, fixing the traceability tag. Two auxiliary fixing components are symmetrically arranged on the upper and lower sides of the traceability tag. One end of each of the two auxiliary fixing components is pinned to either the traceability tag or the first clamping component, and the other end is respectively connected to the tail fin. Extending outwards from the distal end, the two auxiliary fixing members each have an adjustment groove along their extension direction. Each of the two auxiliary fixing members has a slidable second clamping member on its adjustment groove. The two second clamping members pass through and clamp onto the fish's tail fin, forming a triangle with the first clamping member to provide three-point auxiliary fixation for the traceability tag, increasing stability, reducing the risk of tag detachment, and adaptively adjusting the width to follow the growth of the fish's tail fin without restricting its growth and movement, thus extending the usage time of the traceability tag and adapting to long-term tracking of fish information.

In the description of this invention, it should be understood that if terms such as "upper," "lower," "inner," "outer," "left," "right," "front," "rear," "top," and "bottom" indicate directions or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the structure or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms describing positional relationships in the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Please refer to Figures 1 to 3This invention provides a fish traceability tag device for recording fish information, installed on the tail fin of a fish. The device includes a traceability tag 1 and auxiliary fasteners 2. The traceability tag 1 is tightly attached to the fish's tail fin. A first clamping member 3 is provided on the end face of the traceability tag 1 that is in contact with the tail fin, penetrating and clamping the tag 1. Two auxiliary fasteners 2 are symmetrically arranged on the upper and lower sides of the traceability tag 1, with one end of each auxiliary fastener 2 pinned to either the traceability tag 1 or the first clamping member 3. The other end extends towards the tip of the fish tail fin and opens outward. Adjustment grooves 4 are respectively provided on the two auxiliary fixing parts 2 along their extension direction. Sliding second clamping parts 5 are respectively provided on the adjustment grooves 4 of the two auxiliary fixing parts 2. The two second clamping parts 5 pass through and clamp the fish tail fin, and are arranged in a triangle with the first clamping part 3 to provide three-point auxiliary fixing for the traceability label 1. The two second clamping parts 5 can move along the adjustment grooves 4 as the fish tail fin grows, and drive the auxiliary fixing parts 2 to unfold outward along the traceability label 1.

[0031] Specifically, the traceability tag 1 is a thin sheet structure that is tightly attached to one side of the fish's tail fin during installation, near the center of the base of the tail fin. The first clamping member 3 is located on the other side of the tail fin opposite to the traceability tag 1, penetrating the tail fin and engaging with the traceability tag 1 to fix it in place. Both auxiliary fixing members 2 are thin sheet structures, symmetrically arranged on the upper and lower sides of the traceability tag 1, i.e., along the width of the tail fin, tightly attached to the tail fin. One end of each auxiliary fixing member 2 is pinned to either the traceability tag 1 or the first clamping member 3, while the other end extends towards the tip of the tail fin and opens outward in a V-shape. Each of the two auxiliary fixing members 2 has an adjustment groove 4, which is elongated and extends along the extension direction of the auxiliary fixing member 2. Sliding second clamping members 5 are provided on the adjustment grooves 4 of each of the two auxiliary fixing members 2. The two second clamping members 5 penetrate the tail fin and clamp it in place. On both sides, two auxiliary fixing members 2 are fixed. The two second clamping members 5 and the first clamping member 3 are arranged in a triangle on the fish tail fin to provide three-point auxiliary fixing for the traceability tag 1, increasing the stability of the traceability tag 1. In the specific implementation of fixing, the fixing positions of the two second clamping members 5 are respectively located at the end of the adjustment groove 4 near the traceability tag 1. This design allows the fish anti-detachment traceability tag device to adapt to the shape of the fish tail fin, without hindering the normal swimming of the fish. As the fish grows, the length and width of the fish tail fin increase. The two second clamping members 5 fixed on the fish tail fin will follow the growth of the fish tail fin and adaptively adjust their positions along the adjustment groove 4 on the two auxiliary fixing members 2 towards the end of the fish tail fin. This will also drive the two auxiliary fixing members 2 to adaptively unfold towards the upper and lower sides of the traceability tag 1, without restricting the growth of the fish tail fin. This allows the fish anti-detachment traceability tag device to adapt to the growth of the fish tail fin without falling off, thus enabling long-term traceability of fish information.

[0032] Please refer to Figure 4 and Figure 5In the above embodiment, the first clamping member 3 includes a first fixing pin 31 and a first clamping seat 32. The first fixing pin 31 is horizontally disposed on the end face of the traceability label 1 that is attached to the fish tail fin. The first clamping seat 32 is provided with a first fixing hole 35 for the first fixing pin 31 to pass through. When fixing the traceability label 1, the first fixing pin 31 is passed through from one side of the fish tail fin so that the traceability label 1 is in close contact with the fish tail fin. The first clamping seat 32 is disposed on the other side of the fish tail fin opposite to the traceability label 1. After the first fixing pin 31 passes through the fish tail fin, it is inserted into the first fixing hole 35 on the first clamping seat 32 so that the first clamping seat 32 and the traceability label 1 are clamped together on both sides of the fish tail fin. A first elastic card 33 is provided in the first fixing hole 35. The elastic card is located on the side wall inside the first fixing hole 35. The tip of the first fixing pin 31 inserted into the first fixing hole 35 is provided with a first slot 34. After the tip of the first fixing pin 31 is inserted into the first fixing hole 35, the first elastic card 33 can be locked in the first slot 34 to lock the first fixing pin 31 and prevent the first fixing pin 31 from separating from the first fixing hole 35.

[0033] Please refer to Figure 7 and Figure 8 The second clamping member 5 includes a slide 51, a second fixing pin 52, and a second clamping seat 53. The slide 51 is disposed on the adjusting groove 4 and closely adheres to one side of the fish tail fin, and is movable along the adjusting groove 4. The second fixing pin 52 is horizontally disposed on the slide 51 and penetrates the fish tail fin. The second clamping seat 53 is disposed on the other side of the fish tail fin opposite to the slide 51. A second fixing hole 54 is provided on the second clamping seat 53 for the second fixing pin 52 to pass through. After penetrating the fish tail fin, the second fixing pin 52 is inserted into the second fixing hole 54 and fixed thereto, so that the second clamping seat 53 and the slide 51 clamp each other on both sides of the fish tail fin. A second elastic card 55 is provided in the second fixing hole 54. The tip of the second fixing pin 52 inserted into the second fixing hole 54 is provided with a second slot. The second elastic card 55 can be locked in the second slot 56, preventing the second fixing pin 52 from separating from the second fixing hole 54.

[0034] When implementing the above technical solution, the two auxiliary fixing parts 2 and the traceability tag 1 can be fixed on the same side of the fish tail fin or on the opposite side. When the two auxiliary fixing parts 2 and the traceability tag 1 are fixed on the opposite side of the fish tail fin, the two auxiliary fixing parts 2 are pinned to the first clamping seat 32. Correspondingly, a pin groove 11 is provided on the first clamping seat 32. The two auxiliary fixing parts 2 are pinned to the first clamping seat 32 through the pin groove 11 and can rotate outward around the pin groove 11.

[0035] It should be noted that when the two second clamping parts 5 are fixed, the initial position of the slide 51 on the two second clamping parts 5 on the adjustment groove 4 is at the end close to the traceability tag 1. When the fish tail fin is growing, the slide 51 moves adaptively along the adjustment groove 4 following the growth of the fish tail fin, without restricting the growth of the fish tail fin.

[0036] Please refer to Figure 4 , Figures 6 to 8 In a further technical solution, several flexible protrusions 6 are respectively arranged parallel to each other on the end faces of the first clamping seat 32, the traceability tag 1, the second clamping seat 53, and the slide 51 that contact the fish tail fin. The flexible protrusions 6 can be locked on the fin spines of the fish tail fin, increasing the friction between the auxiliary fixing component 2 and the traceability tag 1 and the fish tail fin, making it less likely for the auxiliary fixing component 2 and the traceability tag 1 to shift and tear the soft strips on the fish tail fin. Moreover, the flexible protrusions 6 have a buffering force, giving the fish tail fin and the auxiliary fixing component 2 and the traceability tag 1 a certain amount of room to move, without restricting the fish's movement in the water. At the same time, it can also prevent the auxiliary fixing component 2 and the traceability tag 1 from rubbing against the fish tail when the fish tail fin swings, reducing damage to the fish tail fin. The flexible protrusions 6 act as a buffer pad, and as the fish tail fin grows, they will be squeezed, contracted, and deformed, playing a stabilizing role, and will not restrict the normal growth of the fish tail fin.

[0037] Please refer to Figure 2 , Figure 3 and Figure 5 In a further technical solution, in order to increase the stability of the traceability tag 1, a third clamping member 7 is provided on the end face of the traceability tag 1 that is attached to the fish tail fin. The third clamping member 7 and the first clamping member 3 are respectively provided at both ends of the traceability tag 1. The third clamping member 7 and the first clamping member 3 have the same structure and can be clamped on the fish tail fin to fix the traceability tag 1.

[0038] Please refer to Figure 3 In the above technical solution, the traceability tag 1 has a traceability code 8 printed or etched on its outer surface, which records fish information. The traceability code 8 is a barcode or a QR code. Since fish need to carry the traceability tag 1 while swimming in rivers for extended periods, to prevent the traceability code 8 from being eroded or corroded by minerals, microorganisms, or algae in the water, and to prevent the outer surface of the traceability code 8 from being worn by aquatic plants or the riverbed, making it difficult for the traceability code 8 to be identified by scanning equipment, a protective film 9 is set on the outer surface of the traceability tag 1. The protective film 9 is a transparent PVC film or PE film, which covers the traceability code 8 to protect it. When a fish carrying the anti-detachment traceability tag is caught and information is collected, it can be collected through the protective film 9, or the protective film 9 can be peeled off for collection.

[0039] Please continue reading. Figure 2 or Figure 3Fish primarily swim using their tail fins, which are crucial for directional control. To avoid hindering their movement, both the traceability tag 1 and the auxiliary fasteners 2 are made of deformable plastic sheets with rounded edges. The plastic sheets are flexible and can deform with the movement of the tail fins. Furthermore, the traceability tag 1 and the two auxiliary fasteners 2 are equipped with flexible silicone edge protectors 10 around their edges to reduce wear and damage to the tail fins.

[0040] In another preferred embodiment, the traceability tag 1 can also be an RFID tag, and its fixing method is the same as that in the above embodiments.

[0041] In practical use, the fish anti-detachment traceability tagging device involves attaching the traceability tag 1 tightly to one side of the fish's tail fin, close to the base of the tail fin. The first directional fixing pin passes through the tail fin and engages with the first clamping seat 32 to clamp the tail fin. The two auxiliary fixing members 2 are then swung towards the tip of the tail and opened outwards in a V-shape to accommodate the shape of the tail fin. When fixing the two second clamping members 5, the initial position of the slides 51 on the two second clamping members 5 on the adjusting groove 4 is near the end of the traceability tag 1. After the second fixing pins 52 on the two slides 51 pass through the tail fin, they engage with the second clamping seats 53 respectively, clamping the tail fin. The fins are clamped together, and the first clamping member 3 and two second clamping members 5 are arranged in a triangle to provide three-point auxiliary fixation for the traceability tag 1, increasing the stability of the traceability tag 1. The two second clamping members 5 are connected to the traceability tag 1 by pins. As the fish's tail fin grows, the two second clamping members 5 will adaptively adjust their positions along the adjustment grooves 4 on the two auxiliary fixing members 2 towards the tip of the fish's tail fin, and drive the two auxiliary fixing members 2 to adaptively unfold towards the upper and lower sides of the traceability tag 1. This does not restrict the growth of the fish's tail fin, so that the fish anti-fall-off traceability tag device can adapt to the growth of the fish's tail fin and will not fall off, thus enabling long-term traceability of fish information.

[0042] When fixing this fish anti-detachment traceability tag device, the traceability tag 1 can be fixed horizontally along the fish's tail fin or vertically along the fish's tail fin, such as... Figure 2 or Figure 9 As shown, when the traceability tag 1 is horizontally fixed, the two auxiliary fixing parts 2 can simultaneously be pinned to the first clamping part 3 or the third clamping part 7 on the traceability tag 1; as Figure 10 As shown, when the traceability tag 1 is vertically fixed, the two auxiliary fixing parts 2 can be pinned to the first clamping part 3 and the third clamping part 7 on the traceability tag 1, respectively. Both can be implemented. When the traceability tag 1 is vertically fixed, one of the first clamping part 3 and the third clamping part 7 can be fixed in a movable fixing method, such as the auxiliary fixing part 2 and the second clamping part 5, which is beneficial to the lateral growth of the fish tail fin.

[0043] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the invention. Those skilled in the art will understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
