Resumen:
In the Argentine Pampa fertile soils were originally covered by grasslands, but at present are intensively cultivated.We assessed the specific composition of the fish assemblage of El Pescado stream and compared it with thatrecorded in 1991?1993, when land use in the watershed consisted in natural pastures. The persistence of the fishassemblage between the two studies was rather high: 0.76. Abundance, biomass and species richness were higherduring drought periods. Connectivity with the huge Río de la Plata hydrographic system seems the mostimportant contribution to the high and stable species richness of El Pescado stream.
