Abstract

This paper describes the fecundity and type of spawning of Moenkhausia intermedia in Ibitinga reservoir, São Paulo State, collected from June 1989 to May 1990. 37 mature females were examined and the average fecundity resulted in 6092 ovocytes. For determination of type of spawning 584 females were used. It was observed that spawning is discontinuous, with annual periodicity and higher, in October and November. Fecundity was related to total length, total weight, body weight and ovary weight. The best correlation was between fecundity and ovary weight.
