Abstract

Total lengths (62-285mm) and body scales from 75 redear sunfish collected by electroshocking from Bob Kidd Lake during October and November 1985 were used for this study. The length-frequency distribution yielded five age groups, however, the body scale analysis revealed eight age groups. The total length scale radius relationship was estimated as, TL = 17.98 + 0.92 Sr . Lengths attained at earlier ages were estimated by the Fraser-Lee method and the Bertlanffy growth model was fitted to the lengths for ages five through ten, and the resulting equation, L₁ = 295 [1 - exp — 0.29 (t - 1.83)], estimated lengths similar to the back- calculated lengths (r = 0.98).
