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

Larvae of migratory fish (Teleostei: Ostariophysi) in the lotic remnant of the Paraná River in Brazil

Zoologia (Curitiba), 2015
Fish larvae and adults are morphologically distinct from each other and have different ecological requirements. Research on the dynamics of ichthyoplankton provides valuable information about the early stages of the life cycle of fish.

An individual-based model for evolutionary effects of selective fishing applied to Pseudoplatystoma corruscans

Physica A: Statistical Mechanics and its Applications, 2012
AbstractThis paper proposes an individual-based model that takes into account the evolutionary effects of selective fishing on exploited populations. The model is an adaptation of the Penna model based on the biology of exploited species and characteristics of fishing. Given the importance of the Pintado Pseudoplatystoma corruscans, a native species of

Quality and digestibility of food ingested by various trophic fish groups in the Upper Paraná River floodplain

Revista de Biología Tropical, 2011
Determining quality of food ingested and digestibility can be helpful in understanding the mechanisms that determine trophic plasticity, which is the ability of a given species to use a more advantageous food source at a given time.

Diferenciação genética entre populações de Pseudoplatystoma corruscans (Agassiz, 1829) (Osteichthyes, Pimelodidae) isoladas pelos saltos de Guaíra do rio Paraná

Acta Scientiarum: Biological Sciences, 2008
Os saltos de Guaíra, também denominados Sete Quedas, constituíam até 1982 uma barreira para a dispersão de peixes migradores. Este trabalho teve por objetivo verificar se populações de Pseudoplatystoma corruscans (Osteichthyes, Pimelodidae) eram isoladas
