Resumo: 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.

O ciclo anual de formação dos anéis foi determinado a partir do cálculo do incremento marginal médio do comprimento padrão para cada idade, mostrando que os anéis se formam no período de maio a julho, decorrentes da queda na temperatura e disponibilidade do alimento no ambiente. O número máximo de anéis encontrados foi 3. A curva de crescimento expressa pelo modelo de von Bertalanffy, usando o procedimento não linear é, para machos; Ls=18,1.[1-e –1,02(t) ] e para fêmeas Ls=16,9.[1-e –1,52(t) ].Universidade Estadual De Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/231810.4025/actascibiolsci.v24i0.2318Acta Scientiarum.
