Abstract |
Swimming performance of the Sheepshead minnow, Cyprinodon variegatus, was measured in a stamina tunnel at the end of life-cycle toxicity tests with the organophosphate pesticides, EPN and Guthion. Swimming stamina was affected by 2.2 micrograms EPN/l but not by 0.88 micrograms EPN/l; these concentrations are about one half of those that significantly affect survival, growth or reproduction. Fish brain acetylcholinesterase (AChE) activity, assayed by the pH-Stat method, was inhibited 72% by 0.88 micrograms EPN/l and 83% by 2.2 micrograms EPN/l. Swimming performance was not affected by Guthion concentrations up to 0.5 micrograms/l; this concentration reduced survival and inhibited AChE 78%. |
