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