Pirarucu management in Rondônia

Overview

Environmental management operations in the Rio Cautário State Extractive Reserve in Costa Marques, Rondônia, have focused on controlling the pirarucu (Arapaima gigas) to maintain ecological balance. While the species is native to the Amazon, it is treated as an invasive species within this specific river basin.

During the second stage of the 2026 managed fishing season, authorities recorded the capture of a significant specimen measuring 2.46 meters and weighing approximately 137.90 kilograms, noted as the largest pirarucu recorded to date in a Rondônia conservation unit.

Between August and October 2026, a two-stage operation conducted by the State Secretariat for Environmental Development (SEDAM) and the Chico Mendes Institute for Biodiversity Conservation (ICMBio) resulted in the removal of over 18 tons of fish, totaling 361 specimens. The initiative involved approximately 40 local extractivists in the capture and cleaning process, generating roughly R$ 180,000 in revenue for the community.
