Aquatic ecosystems are among the richest in biodiversity on the planet but also the most threatened. For this, most of them are protected. However, in Brazil, the creation and expansion of conservation units are biased towards terrestrial ecosystems and focused on the Amazon. Planning for the conservation of aquatic environments is a gap in scientific and applied practice, although it is an important trend in the scientific literature. Therefore, in this dissertation, we evaluated the representativeness of the biodiversity of freshwater fish and aquatic flora of the Paraná Hydrographic Region in its current network of conservation units and indigenous lands, as well as proposed priority areas for the conservation of these species. We find that 6.3% of the region is protected. However, on average, less than 10% of the distribution of the species is covered. Furthermore, our spatial prioritization analyses show that the increase in 30% of protection in the region would cover an average of 48% of the species distribution. Results like these can be used to support the planning and implementation of conservation actions aimed at protecting and managing the aquatic biodiversity of this hydrographic region.
