Two-year-old yellow perch (Perca flavescens) from Chautauqua Lake in western New York State were examined using short-term static bioassay techniques to determine possible deleterious subtoxic effects of Diquat (l,l'-ethylene-2,2'-dipyridylium dibromide), an aquatic herbicide commonly used in the lake. Under laboratory conditions, a significant level of respiratory stress was suffered by fish at Diquat concentrations similar to those applied to the lake during weed control measures and at concentrations significantly lower than those causing death (1 to 5 ppm).
