dc.description.abstract | Mean biomass (B) and production (P) of fish in two small tributaries of the Paraná River (Paraná, Brazil) were 61 kg ha 1 and 48 kg ha 1 yr 1 in the Caracu River and 29 kg ha 1 and 26 kg ha 1 yr 1 in the Agua do Rancho River, respectively. Matrix correlation analysis revealed high positive correlations of both B and P to maximum depth and hiding places and, at a lower level of significance, to mean depth, pH and oxygen level. Lower B and P values were found in the Agua do Rancho River, whose valley has retained a more natural character, rich canopy and scarcity of macrophytes, but also lower conductivity and nitrogen and phosphate levels than those in the Caracu River. | en |
