The economic displacement of thousands of fishers in the Pantanal, Brazil: A telling story of small‐scale fisheries marginalization worldwide.

Fish and Fisheries, Volume 25, Issue 6, Page 951-958, November 2024.
Abstract A new policy in the Pantanal wetland, Brazil, aims to economically displace thousands of artisanal fishers from one‐third of the region. The legislation disregards several FAO Voluntary Guidelines for Securing Sustainability in Small‐Scale Fisheries' guiding principles (SSF guidelines). Considering that 2024 marks the 10th anniversary of these

Spar genetic analysis of two invasive species of Cichla (Tucunaré) (Perciformes: Cichlidae) in the Paraná river basin = Análise genética via spar, de duas espécies de Cichla (Tucunaré) (Perciformes: Cichlidae) introduzidas na Bacia do rio Paraná

Acta Scientiarum: Biological Sciences, 2011
The introduction of exotic species in lake ecosystems has been greatly highlighted in the literature worldwide. Since introduction may threaten diversity of native fish, the issue turns up to be of paramount importance.
