Problems solved by technology

[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 collisions such as fish being attacked, making it impossible to track fish information. Some metal wire marks may corrode and rust in the fish body after being penetrated into the fish body, causing damage to the fish and Affect the actual function of the line mark

Embodiment 1

[0022] Such as Figure 1-4 As shown, a traceable device carrying fish biological information includes a mark pole 2, a mark cap 7 connected to the mark pole 2, the mark pole 2 and the mark cap 7 are metal rods and metal caps, and the length of the mark pole 2 is the mark cap 7 5 times the diameter, the pole 2 at the junction of the pole 2 and the cap 7 is provided with a break hole 6, the distance from the break hole 6 to the cap 7 is 1 / 5 of the total length of the pole 2, and the front end of the pole 2 is a tapered head, The taper of the conical head at the front end of the pole 2 is 38°. The design of the conical head is beneficial to reduce the resistance of the marking machine or when it is inserted into the fish body, and can quickly push the pole 2 into the fish body completely. There are also barbs on the surface, the angle between the barbs and the conical head is 8°, the surface of the benchmark 2 is also provided with uniform through holes 3, the diameter ratio of t...

Embodiment 2

[0026] Such as Figure 1-4As shown, a traceable device carrying fish biological information includes a mark pole 2, a mark cap 7 connected with the mark pole 2, the mark pole 2 and the mark cap 7 are metal rods and metal caps, and the length of the mark pole 2 is preferably the mark cap 7 is 6 times of the diameter, which is conducive to the effective fixing of the benchmark rod 2 in the fish body, and avoids the situation that the benchmark rod 2 is too short and the standard cap 7 is too large to cause the traceability device to fall off easily. The break hole 6, the distance from the break hole 6 to the mark cap 7 is preferably 4 / 15 of the total length of the mark pole 2. The designed break hole 6 can break the end part of the mark pole 2 during the pulling process, so as to avoid fish pulling the mark pole when pulling aquatic plants. 2. Excessive mechanical damage is caused to the fish. The front end of the pole 2 is a conical head. The taper of the conical head at the fr...

Embodiment 3

[0029] When the device is actually working: First, the device is used to track many fish, such as large yellow croaker, dolphin, tuna, etc. After the researchers catch the target to be marked, they will collect biological information, and the collected biological information data can be input into the electronic In the chip 9, in order to carry out biological information comparison and research when the target is captured next time, after the data input of the electronic chip 9 is completed, the device is placed in the tissue of the dorsal fin and tail of the target by a marking machine or manually, and the placement position should be according to the target. The structure of the object chooses the position with the least damage. The pole 2 of this device is similar to a metal wire inserted into the fish body, which will cause little muscle damage when the fish swims. When the device is placed into the target, the cone at the front end of the pole 2 will The barbs on the head ...

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...
