Larval white perch were subjected to interacting power plant conditions of total residual chlorine (0.00 to 0.30 mg/l), elevated temperature (2, 6, and 10/sup 0/C), and exposure time (0.08, 2.0, and 4.0 h) at acclimation temperatures of 15 and 23/sup 0/C. Mortality observations were conducted up to 96 h after exposure. Acclimation temperature was a significant factor contributing to the effects of simulated power plant conditions during the low and high thermal conditions. Larvae tested at 23/sup 0/C generally showed greater mortality at all treatment levels than those tested at 15/sup 0/C. Mortality of test organisms during a 4-h exposure at the higher acclimation temperature was greater than 85% at elevated tempeatures greater than 6/sup 0/C regardless of other treatment factors. Mortalities as low as 30% were observed at the lower acclimation temperature.
