Abstract: In this study, has been used water quality indices and remote sensing tools to support fish farming planning and monitoring in the Graminha Reservoir, São Paulo, Brazil. Data collected between January 2020 and May 2024 by the São Paulo State Environmental Agency were used to calculate the Water Quality Index (WQI), which considers the Trophic State Index (TSI) and the Water Quality Index for Aquatic Life Protection (WQIALP). This work underscores the importance of continuous monitoring and careful management of water resources to safeguard the environment and sustain fish farming activities. The suggested plans include cutting down on pollution, controlling land use around the reservoir, and better planning of fish farming based on water changes. It is also important to adjust fish farming methods to different water quality conditions. Using remote sensing is helpful for planning and checking fish farming activities in reservoirs.
