Fig. 3 in Estimating size at first maturity (L ) from Gonadossomatic Index (GSI) data

Fig. 3. Individual distribution of female gonadossomatic index (GSI) according to the total length in four fish species. Animals captured using seine and gill nets over 17 monthly samples (November/2002 to May/2004) from two sites (lagoa do Casamento and lagoa dos Gateados, Rio Grande do Sul State, Brazil). Vertical lines or areas represent published estimates of size at first maturity (L50).
