Data on the fish populations of lentic water bodies in the Paraná River are given for different areas sampled over more than twenty years. Three kinds of environment are considered: small, medium and large lagoons. Each kind has a particular fish population, the characteristics of which are described. Fish populations are also considered in relation to the macrophytes along the Paraná River. In general Prochilodus lineatus is the most important species, both in numbers and in biomass, in the majority of the lagoons. Considerations related to size and age of fish species are also discussed.
