specific Embodiment approach 1

[0018] Specific implementation mode one: this implementation mode distinguishes and marks the flounder flounder individual according to the following steps:

[0019] 1. Cut off the N adjacent fin rays in the dorsal fin as the starting point O of the mark, N≥2;

[0020] 2. Count M fin rays from the starting point O to the head or tail, and then cut off the Mth fin ray, M≥2; the cut fin rays are located between the starting point O and the head, and the number is the front back N-M; the cut off fin rays are located between the starting point O and the tail, and the number is N-M on the back; that is, the mark is completed;

[0021] Wherein, in step 1, the adjacent N fin rays in the dorsal fin are randomly cut off.

specific Embodiment approach 2

[0022] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is: in step 2, count P and Q fin rays from the starting point O to the head and tail respectively, and then cut the P and Q fin rays If P≥2 and Q≥2, the individual number of this fish is P-N-Q. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0023] Specific implementation mode three: this implementation mode distinguishes and marks the flounder flounder individual according to the following steps:

[0024] 1. Cut off the adjacent N rays of the anal fin as the starting point O of the mark, N≥2;

[0025] 2. Count M fin rays from the starting point O to the head or tail, and then cut off the Mth fin rays, M≥2; the cut fin rays are located between the starting point O and the head, and are numbered as the front abdomen N-M; the cut off fin rays are located between the starting point O and the tail, numbered as the hind abdomen N-M; that is, the mark is completed;

[0026] Wherein, in step 1, the adjacent N fin rays in the anal fin are randomly cut off.

Abstract

The invention discloses a method for differentiating and marking flounder individuals, and relates to a marking method for differentiating fish individuals. By the aid of the method, the problem that electronic marks are unsuitable for differentiating flounder individuals can be solved. The method includes firstly, cutting off adjacent N fin rays to be used as marking starting points O; secondly, counting M fin rays from the starting points O to the heads or the tails of the flounder individuals and then cutting off the M fin rays; numbering the flounder individuals as N-M to completely mark the flounder individuals. The N is larger than or equal to 2. The M is larger than or equal to 2. The method has the advantages that numbers of the individuals can be quickly determined from numerous fish fins of flounder, and accordingly the individuals can be efficiently and accurately identified.

Description

technical field [0001] The invention relates to a marking method for distinguishing fish individuals. Background technique [0002] It is currently the most commonly used method to distinguish individual animals by implanting electronic tags in the body. Card reader scanning can quickly obtain information on individual animals for differentiation and identification; moreover, electronic tags can be used for a long period of time after implantation Work. However, the use of electronic markers also has a high cost. During the implantation process, the wounds are deep and the wounds are deep and the damage is large. Moreover, the inside of the wounds caused by the syringes cannot be disinfected, which can easily cause infection and lead to animal death. . [0003] Flounder and flounder belong to the class Osteichthyes, order Pleuronectiformes, commonly known as flatfishes, and can be divided into families Bothidae, Pleuronectidae and Soleoidae. Flounder is an important part ...
