Summary, Etc. Note: |
Abstract: The acute toxicities of the candidate fish anesthetic, quinaldine sulfate (QdSO4), were determined against selected species of coldwater and warmwater fishes. The LC50's (concentrations producing 50 percent mortality) were derived for 3-, 6-, 24-, and 96-hour exposures in bioassays with different temperatures, hardnesses, and pH's. In very soft water QdSO4 solutions are acidic and considerably less toxic than in harder water. This lack of activity is attributed to a decrease in the pH of the test solution which thereby decreases the concentration of the active, un-ionized form of the molecule. |
