Problems solved by technology

The downside is that the amputated fin will continue to regenerate in many cases
Therefore, finning is usually only used for salmon whose adipose fins are completely unable to regenerate

Embodiment

[0014] Example: refer to Figure 1 to Figure 3 , a fish metal wire marker, comprising a wire marker body 1, wherein: the front end of the wire marker body 1 has a wedge-shaped head 1b; the tail end of the wire marker body 1 has a split tail end 1c, and the split tail end 1c A cylindrical impact hole 1d is formed on the central axis of the base; part of the side of the line mark body 1 is a cylindrical surface, and the other part is a non-cylindrical marking surface 1a. The wedge-shaped head 1b of the wire mark body 1 can reduce resistance during the process of penetrating into the marking target. Since the line marker body 1 is made of metal and has elasticity, the split tail end 1c is also elastic. During the injection process, the split tail end 1c is at a position where they are close together. After entering the working depth, the split tail end 1c It is more open than the injection process, so it can get stuck in the marking target. The cylindrical impact hole 1d is for...

Abstract

The invention discloses a metal line marker for fishes. The metal line marker comprises a line marker body, and the front end part of the line marker body is provided with wedged head; the tail end of the line marker body is provided with a furcal tail end, and a basal central shaft of the furcal tail end is provided with a cylindrical impact hole; a part of the side face of the line marker body is a cylindrical surface, and the other part of the side face of the line marker body is a marking surface which is not a cylindrical surface); in the process of sticking the wedged head of the line marker body into a marked target object, the resistance can be reduced; because the line marker body is made of metal and has elasticity, the furcal tail end also has elasticity; in the process of injection, the furcal tail end is located at a close convergence position, and after entering into an operating depth, the furcal tail end is in a more open state compared with the injection process, therefore, the furcal tail end can be clamped in the marked target object; and the cylindrical impact hole is used for facilitating the accommodating of striker parts for continuously and rapidly calibrating so as to improve the operating speed. The metal line marker for fishes disclosed by the invention has the advantages of low possibility of falling off, quickness for manufacturing, low requirement on machining accuracy, and stable and clear identification number, and is suitable for batch production.

Description

technical field [0001] The invention relates to an artificial marker, in particular to a fish wire marker. 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. There are two types of labeling techniques: in vitro labeling and in vivo labeling. In vitro labeling methods include fin cutting method, spine cutting method, pigment labeling method (specifically, dyeing method, ink-injecting method, fluorescent pigment labeling method, etc.), external standard (including penetrating body mark, arrow mark and internal anchor mark), etc.; in vivo Marking methods include wire...
