Abstract

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 Steindachnenna insculpta 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.
