Laboratory-derived findings and dated field studies of thermal preferences of fishes frequently dictate thermal criteria for power plant discharges. To better understand thermal tolerances and develop more accurate criteria, especially during the summer months, 56 fish were tagged with temperature-sensing ultrasonic transmitters and monitored with continuous telemetry to record thermoregulatory behavior in and around the heated discharge at the Tennessee Valley Authority`s Cumberland Fossil Plant on the Cumberland River. During three seasons (summer 2012, winter-spring 2013, and summer 2013) an array of submersible ultrasonic receivers (SURs) in the vicinity of the discharge logged thousands of observations on the temperatures used by Channel Catfish Ictalurus punctatus, Smallmouth Buffalo Ictiobus bubalus, Largemouth Bass Micropterus salmoides, and Striped Bass Morone saxatilis. Tagged fish of each species spent at least some time in the thermal plume, though each species used the heated discharge differently. Variation in plume usage was described as a function of several continuous environmental variables with Generalized Linear Mixed-Effects models. Largemouth Bass frequently occupied water that exceeded their published upper avoidance limits (29 and 30°C) and the probability of plume usage was most strongly related to fish size. Smallmouth Buffalo rarely exceeded their upper avoidance limit (34.5°C) and the probability of plume usage was most influenced by ambient river temperatures. Channel Catfish regularly exceeded their upper avoidance limits (32 and 34°C) and the probability of plume usage was mainly influenced by time of day. Striped Bass seldom exceeded their upper avoidance limit (24°C) and probability of plume usage was predicted most strongly by the magnitude of the difference between ambient and discharge temperatures. The actual thermal exposure of these fishes documented during this study will help provide more realistic criteria for regulatory standards.
