Method for marking fish individual

Abstract

The invention provides a method for marking a fish individual. A dorsal fin position, a pectoral fin position, a pelvic fin position and a tail fin position of the individual are punched and marked, holes at different positions represent different figures, and the sum of the figures represented by the holes is a serial number of the fish individual, thereby achieving a marking range from 1 to 4999. The marking method can achieve permanent marking of the fish individual, is good in safety, high in marking efficiency and low in cost, accordingly meets the requirements of common fish breeding and scientific experiments, only needs a pair of punching forceps and is especially suitable for marking of fish individuals under the hard conditions outdoors.

Description

technical field [0001] The invention belongs to the technical field of fish genetics and breeding, in particular to a method for individual marking of fish. Background technique [0002] At present, when marking fish individuals, the commonly used marks are external tags, that is, a tag with a specific shape is attached to the fish body for identification, mainly including Floy tags and T-shaped tags, which are disclosed in the prior art. It is used for tagging of operculum fish (see patent application document 201010267335.1), fish metal wire marking (see patent application document 201110329502.5), this marking method is easy to be caught by fishing nets, or between thin lines or short rods Intertwining with each other will not only cause the loss of marks, but also be easily discovered and attacked by predators, causing damage to the fish body or affecting its normal activities. There is also a built-in marker, the most commonly used is the PIT marker, that is, a radio f...

[0002] At present, when marking fish individuals, the commonly used marks are external tags, that is, a tag with a specific shape is attached to the fish body for identification, mainly including Floy tags and T-shaped tags, which are disclosed in the prior art. It is used for tagging of operculum fish (see patent application document 201010267335.1), fish metal wire marking (see patent application document 201110329502.5), this marking method is easy to be caught by fishing nets, or between thin lines or short rods Intertwining with each other will not only cause the loss of markings, but also be easily discovered and attacked by enemies, causing damage to the fish body or affecting its normal activities

There is also a built-in marker, the most commonly used is the PIT marker, that is, a radio frequency marker is injected into the abdominal cavity of the fish with a syringe; the fish otolith fluorescent marker method is also disclosed in the prior art (see patent application document 201110172710.9). The marking method has a good individual marking effect, can also reduce the damage to the fish body, and at the same time improve the marking efficiency, and has little impact on the fish breeding process, but its cost is high, and it is generally marked when the fish is small

[0003] In order to reduce the cost and meet the requirements of fish breeding, the present invention provides a method of marking by punching fish fins, which can not only reduce the cost, improve the marking efficiency, but also not affect the breeding. This kind of research has not been reported so far.
