Mark-recapture techniques were used during spring 1982 and 1983 to estimate the abundance of harvestable size paddlefish (Polyodon spathula) in Watts Bar Reservoir, Tennessee. Results indicated a harvestable population in 1982 of 3,421 fish (95% confidence interval of 2,184 to 6,665). Aging studies indicated a relatively young population with an abrupt decrease in survival after the ninth year. This decrease was attributed to extreme fishing mortality on these older age classes before July 1980 when Watts Bar Reservoir was closed to net fishing. Estimated annual growth of adult paddlefish...

Ultrasonic tracking was conducted on 11 smallmouth bass (Micropterus dolomieui Lacepede) in Center Hill Reservoir, TN from 24 May 1973 to 25 July 1974. Transmitters which had an average life of 30.4 days, were implanted in the body cavity and were a successful tool for studying fish movement and behavior. Factors observed were "homing" behavior of displaced fish, horizontal movement, distance ranged offshore, depth ranges, water temperature, and habitat preference. Also determined were correlations between fish movement and water temperature, barometric pressure, water turbidity, water...
