Embodiment

[0025] In 2012, during the transportation of turbot finished fish and live fish in a Yantai aquatic product company in Longkou City, Yantai City, Shandong Province, we used the atomization anesthesia technology described in the present invention to anesthetize commercial turbot fish, specifically Methods as below:

[0026] (1) Ethyl m-aminobenzoate methanesulfonate (abbreviated as MS-222) is used as the anesthetic agent. Dissolve MS-222 in distilled water with a solution concentration of 300mg / L and a solution temperature of 6°C. Put the MS-222 aqueous solution into the water tank of the ultrasonic nebulizer, and the anesthetic nebulizer is blown out from the trachea. Put the organ into the mouth of the fish to be anesthetized, spray the atomized substance, and spray each fish for about 10-20 seconds, and wait for 5 seconds after the fish stops struggling and jumping.

[0027] (2) Afterwards, use an anhydrous container to transport the anesthetized fish, and keep the environm...

Abstract

A transportation method of narcotized fish by atomized anesthetic includes (1) utilizing ethyl 3-aminobenzoate mesylate (abbreviated as MS-222) as anesthetic, and melting the MS-222 into distilled water or purified water to allow the solution concentration to range from 200mg / L to400mg / L and the solution temperature to range from 6 DEG C to 8 DEG C; (2) utilizing a ultrasonic atomizer, and putting the anesthetic solution into a tank of the ultrasonic atomizer to allow the atomized anesthetic to be blown out from a gas guide tube; placing the gas guide tube into a mouth of fish to be narcotized, spraying the atomized anesthetic till the fish stops struggle, and lasting for 5 seconds continuously, namely 10 to 20 seconds for each fish; (3) maintaining a wet environment during transportation of the narcotized fish, placing the narcotized fish into normal water, at temperature at 10 DEG C to 20 DEG C after reaching a destination, oxygenating continuously and allowing the narcotized fish to recover after 10 to 20 minutes.

Description

technical field [0001] The invention relates to an anesthesia method in breeding technology, in particular to a fish atomization anesthesia transportation method. Background technique [0002] Anesthesia technology is widely used in manual operations such as fish transportation, marking, sampling, and measurement, which not only brings great convenience to the above operations, but also reduces the damage to the fish body. However, in the anesthesia used for commercial fish transportation, the method of bath anesthesia will cause more anesthetic residues on the body surface of commercial fish, and the anesthetic dosage is relatively high, which increases the economic cost of anesthetic; the operation of injection anesthesia is complicated, and the injection The dose is difficult to control, and there are more anesthetic residues in the anesthetized fish, and the anesthetic metabolism cycle is long. [0003] At present, there are many patents and papers on fish anesthesia, b...
