Gonadosomatio index (RGS) , mean ovaries length and weight variations has been analysed in order to verify if they may be used as quantitative indicators of spawning period and gonadal development in Micropogonias funieri, population I (23º-29ºS). The analysis of the relationships between gonadosomatio index and total weight single valuesy for females in the same maturity stage, didn't show dependence, being a constant value for each stage, which makes it useful as an a indicator of gonadal development. The three indices showed cyclic Variations with modal values corresponding to the three spawning periods (autumn, winter and spring-summer).Analisaram-se as variações da relaçao gonadossomática (RGS), do comprimento e do peso médios dos ovár...
