Increased population and industrial pressures have focused attention on the need for an accelerated and effective program to prevent and control pollution-caused fish kills in Tennessee waters. A training program to facilitate more rapid and accurate determination of the extent, severity, and probable cause or causes has been developed by the Tennessee Game and Fish Commission. Game and Fish Officers are located in each of Tennessee's 95 counties, and they comprise a readily available source of manpower to implement the program. The Officers must be specially trained in fish welfare so that they will react quickly and efficiently in the event of a fish kill. A training program and manual for investigation of pollution and fish kills for Game and Fish Officers have been developed. All Officers in Tennessee have completed the first two-day pollution school of a proposed series of courses. The school was conducted by personnel from both the Game and Fish Commission and the Tennessee Stream Pollution Control Board.
