What is sedation technique in fish transport?
Among the broad spectrum of anaesthetics,
tricaine methanesulfonate (MS-222) and quinaldine
appear to be used most frequently. MS-222 is a very mild tranquilizer and fish easily recover from its effects even after a long stupor. Horváth, Tamás and Tölg (1984) recommend to apply MS-222 to water at the rate of 20 mg.
Can you perform surgery on a fish?

Submersion into ice water bath (5 parts ice/1 part water, 2-4o C) for at least 20 minutes to ensure death
.
How do you make Tricaine solution?
To use Tricaine as an anesthetic,

How do you cull zebrafish?

Immobilization by submersion in ice water (5 parts ice/1 part water, 0-4o C) for at least 10 minutes following cessation of opercular (i.e., gill) movement
.
Why anaesthetics are used in transportation of ornamental fish?
Conversely, anesthesia
reduces metabolic rate, need for oxygen, activity, and response to stress
(Brown, 2011; Skar, Haugland, Powell1, Heidrun, & Samuelsen, 2017), enabling fish to be transferred in higher densities more efficiently.
Which chemical is used as antiseptic in fish transport?

|---|
Can you intubate a fish?
Fish are immobilized in an imaging chamber followed by oral intubation
. Subsequent delivery of anesthetic-containing water is achieved via a peristaltic pump. The setup of the system will take ∼90 min for two adult zebrafish, and it requires only a little previous experience of working with zebrafish.
What is a fish doctor called?

What is gas anesthesia called?
Anesthetic gases (nitrous oxide, halothane, isoflurane, desflurane, sevoflurane), also known as
inhaled anesthetics
, are administered as primary therapy for preoperative sedation and adjunctive anesthesia maintenance to intravenous (IV) anesthetic agents (i.e., midazolam, propofol) in the perioperative setting.
Is propofol a general anesthetic?
Propofol is used as an “induction agent”—the drug that causes loss of consciousness— for general anesthesia in major surgery
. In lower doses it is also used for “conscious sedation” of patients getting procedures on an outpatient basis at ambulatory surgery centers.
