ABSTRACT
The Araguaia River is an important watercourse located in Central Brazil and well known for its diversity of fish fauna. Differences between landscape and resources in the distinct environments existing in a floodplain can determine the success of a species. This study presents a list of ichthyofauna species found in lentic and lotic environments in the floodplain of the Araguaia River basin, bordering Mato Grosso and Goiás States. We carried out sampling in July 2019, during the dry season, using diverse fish collection strategies, such as waiting nets, trawl, cast net and fishing rods. Were distributed 12 sampling points between lentic and lotic environments and we captured a total of 168 individuals of 42 species, 19 families and six orders. The predominant orders were Characiformes, Siluriformes and Cichliformes, while the families were Serrasalmidae, Characidae, Triportheidae, Curimatidae and Anostomidae. The genera Triportheus, Psectrogaster and Moenkhausia were the most abundant, while Pimelodus was the most dispersed. Results showed greater abundance and diversity in the lentic environment than in the lotic one, with top-of-the-chain species in both. The variance between environments and the presence of species that are endemic, recently described, of undefined taxonomic status, and bioindicators, highlight the importance of conserving and further studying the ichthyofauna in the Araguaia River basin.(AU)
