Abstract

Cará, Satanoperca pappaterra (Osteichthyes, Cichlidae) age and growth estimates were taken from their scales growth rings, showing good consistence, according to the variation coefficients. The ring formation annual cycle was determined by calculating the standard length average marginal increment for each age. This showed that the rings are formed from May to July, due to the temperatures and food availability decrease. The highest number of rings found was 3. The growth curve, expressed through von Bertalanffy model, using the nonlinear procedure, is: Ls = 18.1.[1-e –1.02 (t)] for males and ls=16.9.[1-e –1.52(t)] for females.
