Summary, Etc. Note: |
Abstract: Antimycin A was subjectedto field trials as a fish toxicant in 20 ponds and lakes and 5 streams in the East, Midwest, and West of the United States. The formulations of toxicant included three on sand grains which are designed to release antimycin uniformly within certain depths, and one formulation in a liquid. Differences in sensitivit among fish suggest possible use of antimycin as a selective toxicant. The efficacy of the toxicant is influence by pH and water temperature, with slightly higher concentrations necessary at high pH or in cold water. Antimycin does not repel fish, and its toxic action on fish appears irreversible. It degrades rapidly, usually within a week. Fish-killing concentrations have little or no effect on other aquatic animals. |
