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 method of tilapia anesthesia of the present invention adopts following processing steps:

[0015] Inject 20L of warm water at 30°C into a plastic bucket, add 2mL of anesthetic clove oil to prepare an anesthetic clove oil solution; the concentration of the anesthetic clove oil solution is: 0.01%; put 31 tilapias weighing about 450g into the anesthetic clove oil In the solution, after 2 minutes, it can be seen that the tilapia swimming slows down and stops until 3 minutes later, the fish rolls over, indicating that the tilapia has been anesthetized. Then move the anesthetized tilapia into normal pool water, and after 3 minutes, the tilapia can resume normal swimming.

Embodiment 2

[0017] A kind of method of tilapia anesthesia of the present invention adopts following processing steps:

[0018] Inject 20L of warm water at 28°C into a plastic bucket, add 2mL of anesthetic clove oil to prepare an anesthetic clove oil solution; the concentration of the anesthetic clove oil solution is: 0.01%; put 28 tilapias weighing about 200g into the anesthetic clove oil In the solution, after 2 and a half minutes, the tilapia swimming can be seen to slow down and stop until 4 minutes later, the fish rolls over, indicating that the tilapia has been anesthetized. Move the anesthetized tilapia into normal pool water, and after 5 minutes, the tilapia can resume normal swimming.

Embodiment 3

[0020] A kind of method of tilapia anesthesia of the present invention adopts following processing steps:

[0021] Inject 1L of warm water at 18°C ​​into a plastic washbasin, add 0.2mL of clove oil to prepare an anesthetic clove oil solution; In the oil solution, after 3 minutes, the tilapia swimming can be seen to slow down and stop until 5 minutes later, the fish body rolls over, indicating that the tilapia has been anesthetized. Move the anesthetized tilapia into normal pool water, and after 7 minutes, the tilapia can resume normal swimming.

Abstract

The invention belonging to the field of aquaculture technology relates to a method of anesthesia for tilapia. The invention is characterized in that, infuse warm water into the container, the water temperature is 18 DEG C-30 DEG C; infuse narcotic clove oil into container to prepare for the clove oil solution; put the tilapia into the clove oil solution, the anesthesia time is: 2-5 minutes, then move the anaesthetic anesthesia into the pool for recovery of 3-8 minutes, the tilapia is recovered to swim normally. The invention applies the clove oil on the market as the anesthesia to anaesthetize the tilapia, the anesthesia effect is good; the clove oil can be used as tooth pain killer for human, so the anaesthetic anesthesia is safe to eat; the price is low, and the applied range is wide.

Description

technical field [0001] The invention relates to a method for tilapia anesthesia, in particular to using clove oil as an anesthetic for tilapia anesthesia, and belongs to the technical field of aquaculture. Background technique [0002] In the prior art, when tilapia is anesthetized, anesthetics such as tricaine (MS-222), quinaldine, and phenoxyethanol are usually added to the container containing the fish at a certain concentration. Non-fish 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 th...
