Abstract

The powdered root of Derris elliptica, which contains the alkaloid, rotenone, has long been used by the natives of tropical countries as a fish and arrow poison. Recently it has been introduced in this country as an insecticide, and is being used by conservation workers to remove rough fish from waters which are to be stocked with game fish. Little or no consideration has been given to the possibility that the poison might kill other members of a lake fauna (thus breaking the food chain) and seriously affect the survival of any fish with which the waters might he restocked. The purpose of the present investigation was to determine the effect of rotenone on various aquatic animals.
