COMPARISON OF THREE CONCENTRATIONS OF AQUA-SED FOR IMMERSION EUTHANASIA OF BUTTERFLY SPLITFIN ().

The efficacies of three concentrations of 2-phenoxyethanol from Aqua-sed were examined to determine the suitability for euthanasia of butterfly splitfin (). Thirty fish were randomly assigned to be immersed in one of three Aqua-Sed concentrations: 0.5, 2, and 6 ml/L.

USE OF TRICAINE METHANESULFONATE, CLOVE OIL AND 2-PHENOXYETHANOL FOR IMMERSION EUTHANASIA OF UNGA CICHLIDS ().

Fish may warrant euthanasia for a variety of reasons, but euthanasia may be difficult to accomplish or confirm because fish can recover from deep anesthesia even after cardiac and respiratory arrest. The efficacies of three types of anesthetics were evaluated to compare their suitability for euthanasia of Unga cichlids (). Thirty cichlids were randomly assigned to be immersed in one of the three anesthetic solutions: tricaine methanesulfonate (MS-222), 2-phenoxyethanol (2-PE), and clove oil (CO) at doses of 1,000 mg/L, 2 mL/L, and 500 mg/L respectively.
