<p>The purpose of this paper was to determine the average total length and the average age at which the first maturation period succeeds in the females of <em>Steindachnenna insculpta </em>caught in Ibitinga Reservoir, SãoPaulo State. The observed values from the maturation curve, adjusted to von Bertalanffy's equation, were the following ones: Loo = 143.5mm and K = 0.381. The first sexual maturation period was detected when they were three years old and 97.73 mm length.</p>

Os valores encontrados através da curva de maturação, ajustados pela equação de von Bertalanffy, foram: Loo= 143,5 mm e K = 0,381. A primeira maturação sexualdá-se com um comprimento total médio de 97,73 mm, aos 3 anos de idade.</p>
