The reproductive biology of Centropomus pectinatus is described from an artisanal fish landings collaborative monitoring programme between May 2012 and April 2013 in estuarine waters in north‐eastern Brazil. The total length ( L T ) at which 50% are mature was 24 cm, corresponding to 37·7% of the maximum recorded L T . Gonado‐somatic indices were variable, but highest values were in June and August 2012. Length‐frequency distributions showed male dominance in smaller length classes (15–30 cm) and females in larger length classes (>30 cm).
