Problems solved by technology

Existing RFIDs can be implanted in fish and show good results. However, squids have a soft body surface and will fall off when implanted with existing RFIDs. Moreover, squids have flexible arms and feet, and the implantation position of the mark is improper or loose. will be pulled out by its arms and legs

Embodiment 1

[0017] Embodiment 1: refer to Figure 1 to Figure 2 , special RFID tag for squid, including body 1, wherein: one end of body 1 is shaped on the head of conical shape, and the side of this head is shaped on spiral pattern 3; The side of the body 1 is radial and has six pieces; the body 1 is formed with a hollow cavity 2 inside. The cavity 2 of the body 1 of the above-mentioned squid-specific RFID tag can accommodate an existing RFID module. The helical pattern 3 can make the main body 1 rub against and squeeze the surrounding sea octopus to generate a certain rotation during the process of injecting the cuttlefish octopus, and make the above-mentioned tail fin 4 also rotate together. When the body 1 of the entire squid-specific RFID tag enters the cuttlefish octopus, it can be predicted that the radial tail 4 also enters the tagged target. The resulting rotation opens up instantly, in other words, the angle between the empennage 4 and the radial direction of the main body 1 g...

Embodiment 2

[0021] Embodiment 2: refer to image 3 , this embodiment makes some changes on the basis of embodiment 1, specifically the empennage 4 is crescent-shaped. This shape can relatively reduce the resistance during insertion, and can make the empennage 21 obliquely insert into the marking target like a plurality of radial nails during the rotation process, so as to prevent the marking from falling off.

[0022] The spiral pattern 3 is convex. It can increase friction and stabilize the rotation.

Embodiment 3

[0023] Embodiment 3: refer to Figure 4 , this embodiment makes some changes on the basis of embodiment 1, specifically, the helical pattern 3 extends to the side peripheral surface of the body 1 . The purpose is to enhance friction and effectively ensure the rotation of the body 1 .

Abstract

The invention discloses a RFID mark special for a cuttlefish, which comprises a main body, wherein one end of the main body is provided with a conical head; the side wall of the head is provided with threads; the side wall of the other end of the main body is provided with a tail which is radial along the side wall of the main body; and a hollow cavity is arranged in the main body. The invention has the advantages that the mark is difficult to drop off after being fixed, the technique is simple and the structure is novel. The mark is fit for being used as a releasing mark for sepiella maindroni de rochebrune multiplication in order to evaluate the multiplication effect.

Description

technical field [0001] The invention relates to a live release tag for aquatic animals, in particular to a special RFID tag for squid. Background technique [0002] Cephalopods are important fishing objects in the world's marine fisheries, and have important economic and medicinal values. The development and utilization of these species have always been valued by countries all over the world. In recent years, with the decline of some marine cephalopod resources, people's research focus on cephalopods has gradually shifted from the simple investigation and assessment of marine resources in the past to the technical aspects of rational utilization, protection and proliferation of marine resources. So far, in the protection, development and comprehensive utilization of marine cephalopods, many scholars at home and abroad have done a lot of preliminary work, which has laid an important foundation for our cephalopod breeding and development. In the 1980s, it was reported that Li...
