Abstract

The use of fish toxicants for rough fish control, fish re- stocking, and density estimations is an accepted tool for fishery management in freshwater systems (Everhart et al. 1975). Among the many toxicants available such as antimycin, copper sulfate, and toxaphene, rotenone has become the most widely used and accepted in the field. Rotenone concentrations ranging from 0.1 to 3.0 ppm are routinely used in freshwater (Siegler and Pillsbury 1946). Krumholz (1948) found rotenone to be effective in collecting small fishes in salt- and brackish water but gave no dosage levels. Sampling in Louisiana estuaries and dredged coastal canals have used rotenone concentrations ranging from 2.0 to 5.0 ppm, respectively (Adkins and Bowman 1976; Perry 1976).
