Abstract Coastal lagoons are ecologically sensitive environments increasingly exposed to human pressures, particularly in regions affected by seasonal tourism. These pressures may alter water quality and induce sublethal biological responses in aquatic organisms. This study evaluated physicochemical and microbiological parameters and cytogenetic biomarkers in the fish Geophagus iporangensis from nine lagoons within the Tramandaí River Basin (TRB), southern Brazil, sampled before, during, and aft
