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 4aIctiología99239 4aIchthyology9119207 4aPeces de Agua Dulce96471 4aFreshwater Fish9117439 4aInland Waters9117440 4aLimnología961825 4aLimnology9147026 4aSabalo913182 4aProchilodus Platensis9137130 4aLaguna Totora9147464 4aCorrientes94086 4aArgentina94258 4aLaguna Gonzalez91471030 tEcosurx0325-108Xgv. 5 n. 9 (1978)w234603 cART a(INICN)34655234634 c234634d234634 aAR-ReUNNbspacAR-ReUNNeaacr2
