Abstract The La Plata basin is the second largest of South America and has supported important river fisheries for more than a century. In this paper, we evaluate first time historical trends landings 21 fish taxa recent population 27 species commercial fishes in lower (Argentina). We compiled three kinds data sets: Total fishery (between 1934 1986) exports (1994‒2019), monitoring programs Chaco Santa Fe provinces Paraná River (2009‒2019), surveys populations Upper (Corrientes, 1993‒2020)...
We applied a multiscale approach to understand the patterns of longitudinal, lateral, and temporal variability in fish assemblage structure large floodplain river explored their relationships with climatic seasonality, hydrological variability, geomorphology. studied 35 connected lakes along 600-km section Paraná River over 5 y. Longitudinal changes were associated latitudinal gradient, whereas seasonality variability. seasonal probably based on different thermal preferences species that...
