Immersion anaesthesia with tricaine
methanesulphonate or propofol on different sizes and strains of silver catfish Rhamdia quelen.
A review of tricaine
methanesulfonate for anesthesia of fish.
Benzocaine hydrochloride, similar to tricaine
, may be used in an immersion and recirculation system for fish and amphibians in a buffered solution up to pH 7.
Benzocaine is similar to the topical anesthetic tricaine
methanesulfonate (MS-222) commonly employed in the sedation, immobilization and anesthesia of poikilothermic animals.
Anaesthetic efficacy of metomidate and comparison of plasma cortisol responses to tricaine
methanesulfonate, quinaldine and clove oil anesthetized channel catfish ictalurus punctatus.
Samples of from 37-332 (mean = 205) fish in each treatment group were over-anesthetized with tricaine
methanesulfonate (MS-222) and dissected.
Among fish collected 10 fish of estimated reproductive size (>25 mm SL; Harrell, 1980) of each species were retained for reproductive analysis, euthanized using tricaine
methane-sulfonate (MS-222), and fixed in 10% formalin.
Safest level of tricaine
methanesulfonate (MS 222) to induce anesthesia in juveniles of matrinxa Brycon cephalus.
Methane Sulfonate, MS-222, Sigma, USA).
At the end of the feeding trial, all fish in each tank were collectively weighed immediately after anesthetizing with tricaine
methanesulfonate (MS222, Sigma, St.
The anesthetics mostly used in fish include the tricaine
methanesulfonate (MS222), benzocaine, quinaldine, 2-phenoxyethanol, clove oil and its derivatives (methyleugenol, eugenol and isoeugenol) (2).
Each day, nine larvae were randomly selected, sedated and killed with an overdose of tricaine
methanesulphonate (MS 222), and individually weighed on an Ohaus scale ([+ or -] 0.
