Avoidance responses of striped bass (Morone saxatilis) and Atlantic menhaden (Brevoortia tyrannus) exposed to simultaneous dechlorinated waters (using SO/sub 2/ to dechlorinate total residual chlorine (TRC) concentrations of 0.00, 0.05, 0.10, and 0.15 mg/L TRC) and elevated temperatures (0, 2, 4 and 6 /sup 0/C) were evaluated at acclimation temperatures of 15, 20, 25, and 30/sup 0/C. Both species showed minimal avoidance to dechlorinated estuarine water (no ..delta..T) at all acclimation temperatures. Elevated temperature (..delta..T) or a combination of ..delta..T and dechlorination were the most important factors influencing avoidance of the test species. Acclimation temperature was an important factor influencing the avoidance behavior of both species exposed to heated-dechlorinated power plant conditions. Greatest avoidance of all test conditions generally occurred at an acclimation temperature of 30/sup 0/C. Both species avoided 34/sup 0/C when acclimated to 30/sup 0/C regardless of the dechlorinated condition.
