< 76 > Aquatic ecosystem conservation Protecting the aquatic wildlife is also a commitment we have taken through the Fisheries Management Program. Its main initiative focuses on raising fingerlings to be released in the reservoirs of the hydroelectric power plants, located in the Grande, Tietê, Pardo, and Mogi Guaçu rivers. The fingerlings repopulation uses the species curimbatá (Prochilodus lineatus), dourado (Salminus brasiliensis), pacu-guaçu (Piaractus mesopotamicus), piapara (Megaleporinus obtusidens), piracanjuba (Brycon orbygnianus), and tabarana (Salminus hilarii). Fish reproduction is carried out in the aquaculture stations at our Barra Bonita and Promissão (SP) power plants. An important biodiversity conservation mechanism is the Macrophyte Monitoring and Management Program. Through field surveys and remote sensing, we can prevent operational risks of the uncontrolled presence of these aquatic plants in the hydroelectric power plants reservoirs. Divided into two phases, the program relies on an automated system that monitors by satellite the displacement of the macrophytes in the water and a management process that involves the analysis of the effluent water quality and the pouring of the plants in the dams' spillways. In 2022, we had to perform an operational maneuver at the Mogi Small Hydroelectric Power Plant (SHPP), in the municipality of Mogi Guaçu (SP). A vessel, which works as a type of floating scissor, mechanically removed an exotic species of macrophyte that had proliferated in the plant's reservoir. In this operation, we worked together with stakeholder groups that use the reservoir mainly for navigation and water supply. Research projects with Unesp, from Botucatu (SP), are under development focused on using certain types of macrophytes for pharmaceutical or cosmetic purposes. 2022 Integrated Sustainability Report > Responsibility aes Brasil
