This paper is a contribution to the knowledgment of some aspects of the reproduction of Sardinella brasiliensis (Steindachner, 1879) from the area between 23º40'S and 24º20'S, Brazil. The individual spawning, fecundity, maturation and gonadal indexes, condition factor and spawning power, have been evaluated for the spawning periods of 1963-64 and 1964-65 and the results were statistically analysed. Fecundity/ total length, total weight, ovarian weight and body weight relations were determined for each period and the results statisticaly compared, showing significant differences between the periods under observation.
