The effectiveness of 2 phenoxyethanol (2 PE), quinaldine (2-methyl quinoline), benzocaine (ethyl 4 aminobenzoate) and tertiary amyl alcohol (TAA) was tested to determine their optimal dosages for rapid induction and recovery in the first experiment, while the second experiment evaluated the effects of low dose quinaldine (175 µl/L) and 2 PE (250 µl/L) with oxygen for 1, 3, 6 and 9 h on the mortality and water qualities at 400 g/L rohu Labeo rohita fingerlings in a truck transport simulation. Optimum dosages of 2 PE (250 µl/L), quinaldine (175 µl/L), benzocaine (40 mg/L) and TAA (1.5 ml/L) were found to have rapid (within 6 min) immobilization and recovery. Very low level of immediate and delayed mortality (<1%) was found across all three transport methods. While 2 PE had dissolved oxygen (DO) concentration above 13 mg/L, quinaldine had lower level. Results suggest that rohu fingerlings at 400 g/L can be transported for 9 hours with oxygen with or without sedatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
