Ichthyofauna of two streams (silted and reference) in the Upper Paraná river basin, Southeastern Brazil Ictiofauna de dois riachos (assoreado e referência) na bacia do Alto Rio Paraná, Sudeste do Brasil

Autor: L. Casatti

Publikováno v: Brazilian Journal of Biology, Vol 64, Iss 4, Pp 757-765 (2004)

In this study the fish assemblages of the silted Águas Claras stream (AC) was compared with that of a reference, the São Carlos stream (SC), so as to identify potential fish indicators of integrity or degradation. Both streams, located about 5 km f
