Fig. 2. Annual catch per unit effort (CPUE) of Brachyplatystoma rousseauxii before and after dam closure. The horizontal dotted line before dam closure depicts the mean annual CPUE between 1998 and 2007. The inserted diagrams show the relative contribution of gilded catfish to river catch before and after closure.
