RESUMO:

Invasions of exotic species in Brazil are one of the factors that most negatively impacts biodiversity. Its existence generates threats and conflicts with native species, causing biological losses to the ecosystem. The Pantanal is one of the Brazilian biomes most threatened by the presence of exotic species in its aquatic ecosystems. In order to monitor biodiversity and use of the fishing resource, the Brazilian government has implemented a control system that uses the Declaration of Individual Fishing (DIFs), in the which each fisherman informs the species caught, the quantity (units and kilos), the locations and baits used. This study aims to investigate the occurrences of invasive fish species, reported in DIFs, and their possible environmental and socioeconomic effects in the region of the municipality of Cáceres in the Paraguay River Basin. In all, 4002 DIFs were evaluated from the years 2019 to 2020. Of the 35 species of fish registered, 10 are exotic (originating in the Amazon basin) were registered in 40 locations, totaling 6,410 kg. However, of the 10 species, only Tucunaré, had already been registered by researchers in the region. Our results indicate the need for actions to confirm the actual occurrence of these reported species and point to two possible scenarios: 1) If the occurrences are confirmed, monitoring, study of impacts on native species, management strategies and evaluation of the economic potential for tourist marketing and fishing. 2) If the records are errors in the IPR records, it is necessary to improve the system used and offer training so that fishermen fill out the guides correctly.
