Lago Paranoá, the urban reservoir at the heart of Brasília in Brazil's Federal District, stands as the only significant fishing water body within the DF and serves as a vital resource for both recreational and small-scale commercial anglers. Formed by the damming of the Rio Paranoá, this large artificial lake sits within one of Brazil's most densely populated urban environments, offering a surprisingly productive fishery amid the backdrop of the nation's capital. The lake is remarkably fertile — estimated fish biomass production exceeds 300 kg per hectare, placing it among the most productive aquatic ecosystems when compared to many temperate and tropical reservoirs worldwide. The local population consumes fish at a rate of approximately 12.8 kg per capita per year, more than double the Brazilian national average of 5.8 kg per capita per year, underscoring the cultural and nutritional importance of this fishery to the region.
