Metal magnetic wire mark for broad tonguefish

Abstract

The invention discloses a metal magnetic wire mark for a broad tonguefish, wherein the metal magnetic wire mark belongs to the technical field of an artificial mark. The metal magnetic wire mark comprises a mark post, and a mark cap which is connected with the mark post. The front end of the mark post is a threaded head. The threaded head is connected with a fixing ring. The front end of the mark post is further provided with an RF chip. An electronic chip is embedded in the mark cap. The surfaces of the mark post and the mark cap are provided with rubber layers. The surface of the mark cap is provided with a character mark and a two-dimensional code. The mark post penetrates through a tissue below the dorsal fin of the broad sole through a marking machine or manually. The mark cap contacts with the surface of the broad tonguefish. The fixing ring is connected with the threaded head at the front end of the mark post, thereby finishing fixation of the metal magnetic wire mark and the broad tonguefish. When the broad tonguefish is captured, biological information acquisition can be performed. The acquired biological information can be input into the electronic chip for performing biological information comparing and research when the broad tonguefish is captured at the next time. Furthermore related data of a tag in the RF chip can be read by means of a card reader.

Description

technical field [0001] The invention belongs to the technical field of artificial marking, and in particular relates to a metal magnetic wire marker for wide body tongue sole. Background technique [0002] Wide-body tongue sole is commonly known as short strong sole fish, flatfish sole, tongue, and beef tongue. Osteichthyes, Plaiceiformes, Glossoid Soleidae. Tongue sole broad-bodied is a warm-temperate offshore demersal fish. The wide body tongue sole likes to inhabit the bottom of sandy and muddy waters. It has no long-distance migratory habit, and only moves between shallow near-shore water and deep-shore offshore water with seasonal changes. It breeds in coastal waters in summer and forages in nearby waters after spawning. Move to deep water area to overwinter in winter. In the early stage, the larva has the abnormal characteristic of moving the right eye to the left. The main food is polychaetes and small crustaceans. 2 age reach sexual maturity. The reproductive...

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
