| Abstract: | The Billings Reservoir shows eutrophic waters due to the large amount of sewage, and consequently, the fish can be a problem for public health. Thus, this project aimed to analyze the histological gills and liver of Nile tilapia to verify morphological changes caused by environment, and the frequency of micronuclei was done, to observe the response to genotoxic activity. We observed histological alterations in gills and livers of Nile Tilapia classified as mild to severe, and the presence of micronucleus. The results enable better environmental monitoring and quality control of this species. |
