Juvenile specimens of largemouth bass, bluegill, and channel catfish were tested to determine their ability to withstand abrupt temperature decreases simulating the environmental impact from a sudden shutdown of a nuclear reactor during the winter. Temperature reductions were administered over 2‐hour and 24‐hour periods to assess the importance of the rate of temperature change and hence the mitigative value of having a holding pond with a one‐day retention time between the proposed cooling tower discharge and the receiving stream. Temperature decreases administered over a 2‐hour period resulted in much greater mortality than decreases of the same magnitude administered over a 24‐hour period. Thus, the value of a pond for mitigation from cold shock was substantiated. Results also indicated that adherence to the U.S. EPA temperature criteria for freshwater fish should provide adequate protection from cold shock.
