Abstract
The acute toxicity of Kepone in freshwater was determined with three fish species,Ictalurus punctatus (channel catfish),Lepomis macrochirus (bluegills), andAnguilla rostrata (American eel). Elvers ofA. rostrata were most sensitive with a 96 h lethal concentration for 50% of the animals tested (LC50) of 35 μg per. 1. Bluegills were slightly less sensitive with a 96 h LC50 of 50 μg per 1. Catfish were most tolerant with a 96 h LC50 of 514 μg per l. Bluegills and catfish exposed to comparable concentrations of Kepone accumulated equivalent amounts in 96 h. This observation in conjunction with the markedly different 96 h LC50's for these species suggest a difference in the ways these fish cope with Kepone.
