Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...

Fisher Behavior While Illegally Fishing for Atlantic Goliath Grouper (Epinephelus itajara, Epinephelinae) on the Amazon Continental Shelf, Brazil

Fisheries Management and Ecology, Volume 33, Issue 1, Page 1-13, February 2026.
ABSTRACT In 2002, the Brazilian government banned fishing for Goliath grouper, Epinephelus itajara (Lichtenstein, 1822), through 2007. This grouper was the first fish species targeted by a specific law in Brazilian environmental legislation. Grouper stocks showed no signs of recovery, so the ban was renewed multiple times since 2007. Official estimates

Local knowledge enhances the sustainability of interconnected fisheries

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our modelling approach allows managers to compare alternative conservation strategies under different socio‐ecological scenarios, highlighting trade‐offs and guiding investment of effort and resources. While immediately valuable for pirarucu management in the Middle Juruá, the framework scales across tiers of applicability, each requiring progressively

Spread of Amazonian Freshwater Fishes Beyond Their Native Ranges

Fish and Fisheries, Volume 27, Issue 1, Page 56-67, January 2026.
ABSTRACT The spread and establishment of Amazonian species outside their native ranges through activities such as sport fishing, aquaculture, and the ornamental fish industry may lead to ecological changes in recipient ecosystems. We investigated the global distribution of Amazonian freshwater fish (AFF) and conducted a case study in the upper Paraná ...
