Sheepshead minnows (Cyprinodon variegatus) were exposed to the synthethic pyrethroid insecticides AC 222,705, permethrin or fenvalerate for 28 d in early life stage toxicity tests. AC 222,705 was 370 times more toxic than permethrin and 30 times more toxic than fenvalerate, with survival and size of fish being the most sensitive measures of effect. AC 222,705 significantly reduced survival of hatched fish at 0.61 μg/L and their average weight at 0.06 μg/L; no effects were detected at 0.03 μg/L. Two of the AC 222,705 concentrations that diminished weights, 0.06 and 0.12 μg/L, were below our limit of chemical detection (0.15 μg/L). Permethrin reduced survival of hatched fish at 22 μg/L; no effects were detected at 10 μg/L. Fenvalerate significantly reduced survival of hatched fish at 3.9 μg/L and both weight and length at 2.2 μg/L; no effects were detected at 0.56 μg/L. The 96‐h LC 50 divided by the no‐effect concentration was 0.8 for permethrin, 9 for fenvalerate and 37 for AC 222,705. The mean bioconcentration factors determined from concentrations measured in whole fish divided by average concentrations measured in exposure water were 480 for permethrin and 570 for fenvalerate; AC 222,705 was not detected in fish that survived the exposure.
