Sustainable Use Units have been carrying out sustainable management since the 1990s in the State of Amazonas, leading to research on the influence of management plans on restoring ecosystems. We developed an integrative review and analyzed official documents, data from the Brazilian government and information obtained from fishermen on the Unini River Extractive Reserve. The review articles were analyzed qualitatively, and a X2 test was used to verify differences in the distribution of proportions of pirarucu between the years after implementing the management. The management plan was the most cited as a solution to the environmental, social, and economic problems identified in the ecosystems. The data showed an increase in the numbers of pirarucu both in State of Amazonas and in the Unini River Reserve, reinforcing the perception of the community and fishermen. This suggests that when management plans are developed with the involvement of the local community, they present potential to restore ecosystems.
