Embryonic, larval and early juvenile stages of fathead minnows (Pimephales promelas) and juvenile amphipods (Hyalella azteca) were exposed to Kelthane, and fathead minnows were exposed to Pydrin in a small self-contained continuous-flow diluter system for approximately 30 days. Survival of the newly hatched larvae was found to be the most sensitive measure of the effect on fathead minnows of both pesticides.
