Problems solved by technology

[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

Embodiment 1

[0016] A kind of carp individual marking method of the present invention adopts following process step:

[0017] First, soak the PIT marker and its syringe in the disinfectant solution for more than 1 minute; anesthetize the carp with an anesthetic, the concentration of the anesthetic is: 1:3000W / V, that is, 1gMS222 is dissolved in 3000ml of water. Put the sterilized PIT mark in the needle of the syringe, hold a carp weighing 10.1 g in the left hand, hold the syringe in the right hand, and pierce the abdominal wall with the needle at 45 degrees from the side close to the carp's ventral rib and anus, and wait until After the needle enters the abdominal wall, push the needle into the abdominal cavity in a direction parallel to the abdominal wall. After the needle enters the abdominal cavity for about 1 cm, gently push the syringe barrel, push the PIT mark into the abdominal cavity of the carp, and then withdraw the needle. Described mark is the PIT mark placed in carp body, and...

Embodiment 2

[0019] A kind of carp individual marking method of the present invention adopts following process step:

[0020] First, soak the PIT marker and its syringe in the disinfectant solution for more than 1 minute; anesthetize the carp with an anesthetic, the concentration of the anesthetic is: 1:3000W / V, that is, 1gMS222 is dissolved in 3000ml of water. Put the sterilized PIT mark in the needle of the syringe, hold a carp weighing 22.6 g in the left hand, hold the syringe in the right hand, and pierce the abdominal wall with the needle at 45 degrees from the side close to the carp’s ventral rib and anus. After the needle enters the abdominal wall, push the needle into the abdominal cavity in a direction parallel to the abdominal wall. After the needle enters the abdominal cavity by about 0.9 cm, gently push the syringe barrel, push the PIT mark into the carp abdominal cavity, and then withdraw the needle.

Embodiment 3

[0022] A kind of carp individual marking method of the present invention adopts following process step:

[0023] First, soak the PIT marker and its syringe in the disinfectant solution for more than 1 minute; anesthetize the carp with an anesthetic, the concentration of the anesthetic is: 1:3000W / V, that is, 1gMS222 is dissolved in 3000ml of water. Put the sterilized PIT mark in the needle of the syringe, hold a carp weighing 84.3 g in the left hand, hold the syringe in the right hand, and pierce the abdominal wall with the needle at 45 degrees from the side close to the carp’s ventral rib and anus, and wait until After the needle enters the abdominal wall, push the needle into the abdominal cavity in a direction parallel to the abdominal wall. After the needle enters the abdominal cavity for about 1.2 cm, gently push the syringe barrel, push the PIT mark into the abdominal cavity of the carp, and then withdraw the needle.

[0024] A total of 3,012 carps were marked, and the ...

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...
