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

open access: yesFisheries 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

open access: yesJournal 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
