W. of the Corrientes Province.  During the years 1974-1977, the studies were performed in several samplings in the whole area were registered 124 species of fishes belonging to 81 genera, 24 families and 11 orders, recording the greatest diversity in the Riachuelo river, where prevail typical fishes of lotic waters. In the pools, swamps and marshes of its basin were registered 73 species, from which 26 were absent in the Riachuelo's waters. Only one typical migratory fish : Prochilodus platensis, was somewhat frequent.  The distributional mechanisms resulting from the rain floods are analized, as well as the integration of new populations, the tropic relations, the contributions of these bodies to the bioproductivity of the Riachuelo's waters, and the possibilities offered by them to the development of the regional pisciculture 4aIctiología 4aIchthyology 4aPeces de Agua Dulce 4aFreshwater Fish 4aInland Waters 4aLimnología 4aLimnology 4aSabalo 4aProchilodus Platensis 4aLaguna Totora 4aCorrientes 4aArgentina 4aLaguna Gonzalez0 tEcosurx0325-108Xgv. 5 n. 9 (1978)w234603  a(INICN)34655234634  aAR-ReUNNbspacAR-ReUNNeaacr2
