Method for making carp individual

Abstract

The invention relates to an individual labeling method of carp, in particular to an individual labeling method that PIT label is injected in the carp body for labeling, belonging to the technical field of aquiculture, which comprises the following steps: firstly, the PIT label and an injector are immersed in disinfection solution for sterilization; then the carp is anaesthetized; the sterilized PIT label is arranged in the injector needle; the abdomen wall is pierced with the needle on the side near the abdomen edge and anus of carp, and then the needle is pushed in the abdomen cavity along the abdomen wall; when the length of needle in the abdomen cavity is 0.8 to 1.0cm, the injector syringe is gently pushed to push the PIT label in the abdomen cavity of carp, and then the needle is extracted out. The invention has the advantages of ability of improving the retention rate of label, less impairment to the carp body in labeling and less influence on carp cultivation.

Description

technical field [0001] The invention relates to a carp individual marking method, in particular injecting PIT markers into carp body for individual marking, and belongs to the technical field of aquaculture. Background technique [0002] In the prior art, when carrying out the individual mark of carp, adopt the external type mark usually, promptly hang on the carp fish body with numbered signboard. Commonly used external signs include Floy markers and T-shaped markers. The former passes a needle and thread through the back of the carp to hang the marker on the carp body surface, and the latter uses a marking gun to mark the marker through the carp tail. [0003] Both of these two types of external markers need to penetrate the body of the carp, so the damage to the carp is relatively large; the other two markers either have a thin line or a short plastic rod left on the fish body. , These thin wires or short rods will be entangled with each other or around other things in t...

[0003] Both of these two types of external markers need to penetrate the body of the carp, so the damage to the carp is relatively large; the other two markers either have a thin line or a short piece of thin plastic rod left on the fish body. , these thin wires or short rods will be entangled with each other or around other things in the pond, which will not only cause the marks to fall off, but also affect the normal activities of carp and even cause damage to the fish body, which will adversely affect the breeding results
