A Growth Study Of Redbreast, Lepomis Auritus (Gunther), And Bluegill, Lepomis Machrochirus (Rafinesque), Populations In A Thermally Influenced Lake

Bluegill and redbreast populations were sampled by electric shocking techniques from two normal areas and an area affected by the heated discharge of a power generation plant at Lake Sinclair, Georgia. Growth of the fish was derived by the Lea method from measurements of the distance between the last formed annulus to the edge of the scale. By comparison of the study areas, temperature was found not to be the controlling factor of bluegill and redbreast growth in the discharge area.
