Anesthetic effects.
Quinaldine has been used for fish anesthesia and is more commonly used for collection of fish in tide pools and coral reefs than is tricaine. In higher concentrations, it can cause a rapid induction. Recovery characteristics are more variable than with tricaine, in part because of the relatively uncontrolled dosing that occurs with the drug in some applications. Quinaldine often does not completely stop muscle movement, and many anesthetists find it more appropriate for sedation than for induction of surgical anesthesia. Long-term sedation/anesthesia has been associated with mortality (Yanar and Kumlu, 2000). Quinaldine can be an irritant to gills and cause corneal damage, particularly when administered at high concentrations for rapid immobilization in captures or when using unbuffered stock solutions administered directly onto the fish rather than mixing the stock into the anesthesia bath water (Stoskopf, 1993).
