The invention discloses a traceable
label for a dolphin, and belongs to the technical field of manual marking. The
label comprises a marking post and a marking cap connected with the marking post, a threaded head is arranged at the front end of the marking post, a fixing ring is connected to the threaded head, a
radio frequency chip is arranged at the front end of the marking post, an
electronic chip is embedded in the marking cap, a rubber layer is arranged on the surfaces of the marking post and the marking cap, the surface of the marking cap is provided with word marks and a two-dimensional code, the marking post penetrates through the tissue of the lower portion of a marking post or the back through a marking
machine or manual operation, the marking cap makes contact with the surface of the dolphin body, the fixing ring is connected with the threaded head at the front end of the marking post, fixation of the
label and the dolphin is completed, biological information collecting can be conducted when the dolphin is captured, and the collected biological information can be input into the
electronic chip, so that biological information comparison and research are conducted when the dolphin body is captured next time; related data of markers in the
radio frequency chip is read by means of a code reader.
