Example Embodiment

[0021] Example 1:

[0022] Such as Figure 1-4 As shown, a traceability device containing fish biological information includes a post 2 and a cap 7 connected to the post 2. The post 2 and the cap 7 are metal rods and metal caps, and the length of the post 2 is the cap 7 It is 5 times the diameter. A break hole 6 is provided on the mark 2 where the mark 2 and the mark cap 7 are connected. The distance from the break hole 6 to the mark 7 is 1 / 5 of the total length of the mark 2. The front end of the mark 2 is a tapered head. The taper of the tapered head at the front end of Marker 2 is 38°. The design of the tapered head is conducive to reducing the resistance of the marking machine or the time Marker 2 inserted into the fish body. It can quickly push the Marker 2 into the fish completely. The tapered head The surface is also provided with barbs. The angle between the barb and the tapered head is 8°. The surface of the benchmark 2 is also provided with uniformly distributed throug...

[0025] Example 2:

[0026] Such as Figure 1-4 As shown, a traceability device containing fish biological information includes a standard rod 2, a standard cap 7 connected to the standard post 2, and the standard post 2 and the standard cap 7 are metal rods and metal caps. The length of the standard post 2 is preferably the standard cap 7 is 6 times the diameter, which is conducive to the effective fixation of the benchmark 2 in the fish body, and avoids the situation that the benchmark 2 is too short and the benchmark 7 is too large to cause the traceability device to easily fall off. The benchmark 2 at the junction of the benchmark 2 and the benchmark 7 is provided with a benchmark 2 The distance between the broken hole 6, the broken hole 6 and the standard cap 7 is preferably 4 / 15 of the total length of the standard rod 2. The designed broken hole 6 can break the end of the standard rod 2 during the pulling process, avoiding fish pulling the waterweed. 2 Causes excessive mech...

[0028] Example 3:

[0029] When the device actually works: First, the device uses to track many fishes, such as large yellow croaker, dolphins, tuna, etc. After the researcher catches the target that needs to be marked, the biological information is collected, and the collected biological information data can be input into the electronic The chip 9 is used to compare and study the biological information when the target is captured next time. After the data input of the electronic chip 9 is completed, the device can be placed in the tail tissue of the target dorsal fin by a marking machine or manually. The placement should be based on the target The structure of the object selects the position with the least damage. The benchmark 2 of this device is similar to a metal wire inserted into the fish body, which is less harmful to the muscles when the fish is swimming. When the device is placed in the target, the front end of the benchmark 2 is tapered The barbs on the head are tightly...

Abstract

The invention provides a traceable device carrying fish biological information, and belongs to the field of fish tagging devices. The traceable device carrying the fish biological information includes a tagging rod, and a tagging cap connected to the tagging rod; a front end of the tagging rod is a cone-shaped head; a radio frequency chip is arranged on a surface of the tagging rod; an electronic chip is embedded in the tagging cap; rubber layers are arranged on surfaces of the tagging rod and the tagging cap; and character marks and a two-dimensional code are arranged on the surface of the tagging cap. A firing pin impacts the tagging cap so as to inject the tagging rod into a tail tissue of a dorsal fin of a fish, the tagging cap contacts a surface of the fish, the traceable device is clamped in a body of the fish; when the fish is captured, biological information can be acquired, and the acquired biological information can be input to the electronic chip so as to compare and research the biological information when the fish is captured next time; the traceable device will not fall, can position, trace and record fish biological information, has strong tracing signals, can be easily injected into the fish body, will not be corroded and rust in the fish body, and will not affect movement of the fish.

Description

technical field [0001] The invention relates to an artificial marker, in particular to a traceable device carrying fish biological information. Background technique [0002] A method of studying fish migration and fish stocks. Mark the fish caught in natural waters and put them back into the original waters. When they are recaptured, they can be used to study the migration, distribution, growth and resources of fish. In 1886, Petersen et al. used the method of marking fish to estimate the size and mortality of fish populations in closed water bodies, and the technology of tagged releasing was developed. [0003] The markers in the prior art are often stuck on the back of the fish body. The markers are easy to be found and are not resistant to corrosion. The use of sign plates for some marks will affect the movement of the fish, and the sign plates may be caught when the fish swims underwater. Aquatic plants affect the fish, or the marks fall off or deform during violent co...
