Anesthesia in fish print PDF emailWritten by Administrator Tuesday February 21 2012 14:52 pmAnesthesia in fishes.By Hsu Wan down rats.Anaesthesia or Anaesthetic means the chemicals that cause the loss of some or all of your feelings by doping is spreading into the central nervous system to inhibit the function of nerve cells in the part of the transfer of information to other neurons to. Cause loss of response to exerted from outside stimulation.Current anaesthesia used in animals, there are many types of water used in fish, but most commonly used include:MS-222 1.0) is the name that the 3-aminobenzoic chemical acid ethylester methanesulfonate or trade name that Tricane and Meta-caine methanesulfonate, which is one type of doping that has been registered by the FDA of the United States, European Nations and countries with fish as food. But I want the fish for at least 21 days after the use of the drug can be consumed. MS-222 has a white powder soluble fragrance comes in both fresh water and salt water thus penetrates through the gums quickly. This type of anesthesia is expensive. 5 g approx 1350 bahtPrecautions on use 1.MS-222 will cause acid-base (pH) of the water is reduced. Not suitable for water containing acid-base, low. 2. should be filled with sodium bicarbonate When made into a slurry concentration should be put in opaque glass bottles and store in the refrigerator for about 3 months to maintain performance. The concentration used. -Salmon concentration 40-50 mg/l.Tilapia and CARP Chanal-catfish 100 mg per liter concentration.-Transport of tilapia is a 24-hour time. The concentration of 30 mg per liter.-Transport of fish for a period of 48 h. The concentration of 25-30 mg/l.-Transport of GuppY is a 48 HR time. The concentration of 70-80 mg per liter.2.0) is that the chemical name ethyl-p-aminobenzoate Benzocaine. Benzocaine is characterized as white powder soluble in water, but very little. Good soluble in acetone and ethanol thatha. Water quality does not make change. If the Bebzocain-hydrocloride will be in the form of soluble, but will make the pH of water is reduced. The user should be careful and select the appropriate purchase. This type of anesthesia can be used in both fresh water and sea water are the same and it is likely that it has been approved by the FDA of the United States, the country fetched MS-222 is cheaper because instead of 100 g approx 1600 baht. Precautions on use, as well as MS-222 The concentration used. -Salmon concentration 40 mg per liter.-Tilapia 100 mg per liter concentration.2-Phenoxyethanol 3.0) are trade names, such as phenoxethol, phenylmonoglycol ether, ether rose. 2-Phenoxyethanol it is a pale yellow liquid resembling gasoline smells slightly soluble Pan.The central feature is a disinfectant, bacteria and fungi. So it is used as an ingredient of cosmetics and medicine. This type of anesthesia is used in significant fish because it is inexpensive. 500 ml volume anesthesia approx 2750 baht.Precautions on use 1. a mixture of ethylene oxide cause irritationThe user should enter the skin, gloves, do not touch directly or. 2. should dissolve in water volume slightly doping people together before pouring into a container that will perform anaesthesia fish. The concentration used. -1.5-inch long fish tailed in size 66 h. 75 mg per liter concentration.Adult Red sailfin Molly-60 h 200-220 concentrations mg per liter.GuppY male-concentrated 180-200 mg per liter.4.0) Quinadine chemical name is 2-4-methyquinoline. Quinadine liquid fuel similar characteristics in yellow sugar dissolved in water. Good soluble in acetone or alcohol smell will reduce performance chun into water with pH less than 5, and the water will fill when quinaldine causes acid increased. Accumulation in fish tissue found after a 24-hour use, cannot be measured as the anesthesia used. Very affordable price 3900 baht 250 ml is used widely.Precautions on use 1. make water acidic so should increase bicarbonate. 2. If the water has low alkalinity values. Each pattern should be applied before in acetone and keep in a bottle is not a solid color, light, and then store in the fridge.The concentration used to stun fish, most commonly used in laboratory studies is in the range of concentrations. 15-60 mg per liter. Depending on the size and type of the fish and during anaesthesia for surgery were found to respond occasionally. Experiments to use in a fish transport found that quinaldine is not appropriate and the death rate is higher than the group that did not use anesthesia. However, although all four types of anesthesia above can help to reduce the response to stimulation from the outside, but what remains is the trial, the report found that such hormone doping Corti received the primeval fish SEO anesthesia increased, which will affect the immune system. ดังนั้นผู้เขียนคิดว่าหากจะทำการสลบปลาแล้วนำไปเลี้ยงต่อ น้ำที่ใช้ควรสะอาดปราศจากเชื้อโรค และควรมีการทดสอบยาสลบกับปลาแต่ละชนิดและระยะเวลาที่ทำการสลบก่อนนำไปใช้จริง เพื่อป้องกันการผิดพลาดที่อาจเกิดขึ้นเนื่องจากปัจจัยต่างๆดังที่ได้เสนอไปแล้ว
