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

Foraging behavior interactions between the invasive Nile Tilapia (Cichliformes: Cichlidae) and three large native predators

Neotropical Ichthyology
The predator-prey relationships between juvenile Nile Tilapia Oreochromis niloticus and native fish species of the Paraná River basin, Brazil, were experimentally examined. Juveniles of O. niloticus were offered to three native predator species (Salminus

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.

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.
