EVALUATION OF ABIOTIC WATER PARAMETERS IN THE RESERVOIR (SURFACE AND DEEP) AT THE SCHOOL FARM OF THE FEDERAL RURAL UNIVERSITY OF THE AMAZ

Abstract

This study evaluated the water quality of the reservoir at the School Farm of the Federal Rural University of the Amazon (UFRA), an aquatic ecosystem of great importance for aquaculture, fishing, and academic research. Physical–chemical parameters such as pH, temperature, conductivity, turbidity, and transparency were measured at different points and depths, following the Standard Methods and comparing the results with the standards established for Class 2 water bodies. Overall, the water presented thermal stability, good transparency, low conductivity, and controlled turbidity, indicating favorable conditions for aquatic life, although the slightly acidic pH in some areas requires continuous monitoring. Maintaining water quality is essential not only for environmental preservation but also for the social and economic sustainability of fish farming, promoting responsible fish production, local income generation, inclusion of riverside communities, and the supply of healthy and high-quality food to the population without compromising natural resources. Furthermore, aquaculture in the Amazon stands out as a promising and environmentally more sustainable economic alternative compared to traditional livestock farming, although challenges such as limited investment, adequate infrastructure, and technical training still restrict the full development of the sector in the region.
