Traceable tag for large yellow croaker

Abstract

The invention provides a traceable tag for large yellow croaker and belongs to the technical field of artificial tagging. The traceable tag for the large yellow croaker comprises a tag rod and a tag cap connected with the tag rod; the front end of the tag rod is provided with a threaded head which is connected with a fixing ring; the front end of the tag rod is also provided with a radio frequency chip; the tag cap is embedded with an electronic chip; the surface of the tag rod and the tag cap is provided with rubber layers; the surface of the tag cap is provided with a work mark and a QR (quick response) code. An operator can penetrate the tag rod through tissue under the tail part of the dorsal fin of a large yellow croaker through a tagging machine or manually so that the tag cap can be in contact with the body surface of the large yellow croaker, then connect the fixing ring with the threaded head at the front end of the tag rod to complete fixation of the traceable tag to the large yellow croaker; when capturing the large yellow croaker, the user can achieve biological information collection, input the collected biological information into the electronic chip for biological information comparison and study when the large yellow croaker is captured next time, and meanwhile, read relevant data of the traceable tag in the radio frequency chip through a code reader.

Description

technical field [0001] The invention belongs to the technical field of manual marking, in particular to a traceable label for large yellow croaker. Background technique [0002] The large yellow croaker has an elongated body and flat sides, with a body length of about 40-50cm. Golden. Tail slender. The scales are small, with 8-9 rows of scales between the starting point of the dorsal fin and the lateral line. 25-27 vertebrae. It usually inhabits deep sea areas, and migrates to the sea to spawn from April to June. After spawning, it is scattered along the coast to seek food and feeds on fish and shrimp. It migrates to the deep sea again in autumn and winter. Swim bladder can make sound; one method of studying fish migration and fish resources in the prior art is to mark the fish caught in natural waters and put them back into the original waters, so that the migration of fish can be studied when they are recaptured , distribution, growth and resources. In 1886, Peterse...

AI Technical Summary

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
