Problems solved by technology

Although tricaine (MS-222) has high efficiency and its safety has been approved by FDA, FDA requires that food fish anesthetized by tricaine (MS-222) must go through a 21-day drug regression period before it can be released on the market. Online sales, and the high price of MS-222 affects its wide application

Embodiment 1

[0014] A kind of carp anesthesia method of the present invention adopts following process step:

[0015] Add 99.98% by weight of water and 0.02% by weight of anesthetic clove oil into a 75L PVC vat to prepare an anesthetic solution. The concentration of the anesthetic solution is 0.01%; the content of eugenol in the clove oil is >85%. Put 21 carps with a weight of about 450g into the anesthetic solution. After 1 minute, you can see that the carp's swimming slowed down and stopped until 2 minutes later, the carp turned over, indicating that the carp had been anesthetized. Then move the anesthetized carp into normal pool water, and after 5 minutes, the carp can resume normal swimming.

Embodiment 2

[0017] A kind of carp anesthesia method of the present invention adopts following process step:

[0018] Add 99.99% by weight of water and 0.01% by weight of anesthetic clove oil into a 75L PVC vat to prepare an anesthetic solution; the concentration of the anesthetic solution is 0.01%; the content of eugenol in the clove oil is >85%. Put 20 carps with a weight of about 1200g into the anesthetic solution. After 2 minutes, you can see that the carp swimming slowed down and stopped until 4 minutes later, the carp turned over, indicating that the carp had been anesthetized. Move the anesthetized carp into normal pool water, and after 6 minutes, the carp can resume normal swimming.

Embodiment 3

[0020] A kind of carp anesthesia method of the present invention adopts following process step:

[0021] Add 99.98% by weight of water and 0.02% by weight of anesthetic clove oil into a 75L PVC vat to prepare an anesthetic solution; the concentration of the anesthetic solution is 0.02%; the content of eugenol in the clove oil is >85%. Put 50 carps with a weight of about 15g into the anesthetic solution. After 2 minutes, you can see that the carp swimming slows down and stops until 5 minutes later, the carp body rolls over, indicating that the carp has been anesthetized. Move the anesthetized carp into normal pool water, and after 8 minutes, the carp can resume normal swimming.

Abstract

The invention relates to an anesthesia method for carp, which belongs to the technical field of aquiculture. The invention is characterized in that the water of 99.98 to 99.99 weight percentage and the clove oil of 0.01 to 0.02 weight percentage are added in to a container to prepare anesthesia solution, and the carp is put into the container to be anesthetized. After being anesthetized for 2 to 5 minutes, the carp is found lying on side in the solution. And then, the carp is put into the waters of a pond. After 5 to 8 minutes, the crap can swim as usual. The anesthesia method of the invention adopts the clove oil that is commercially available and has good anesthesia effect. The clove oil can be used for soothing toothache of human. So the clove oil is safe to anesthetize the carp and does not affect edibleness. In addition, the clove oil has the advantages of low cost and wide application range.

Description

technical field [0001] The invention relates to a carp anesthesia method, in particular to using clove oil as an anesthetic to anesthetize carp, and belongs to the technical field of aquaculture. Background technique [0002] In the prior art, when carp is anesthetized, anesthetics such as tricaine (MS-222), quinaldine, and phenoxyethanol are usually added to a container containing fish at a certain concentration. After a period of time, carp can be anesthetized. [0003] Among these anesthetics, the anesthesia time of some anesthetics is relatively long, and most of them have certain problems in terms of safety. Although tricaine (MS-222) has high efficiency and its safety has been approved by FDA, FDA requires that food fish anesthetized by tricaine (MS-222) must go through a 21-day drug regression period before it can be released on the market. Online sales, and the high price of MS-222 affects its wide application. Contents of the invention [0004] The purpose of t...
