In this study, it was aimed to determine the oxidative stress in the tissues of the swordtail fish (Xiphophorus hellerii Heckel, 1848) after exposed to the active ingredient of Prozac® and one of the SSRI (Selective Serotonine Reuptake Inhibitor) group antidepressants, Fluoxetine Hydrochloride, which is considered to be safe cardiovascular. It is widely used in the treatment of depression, which is one of the increasing health problems in the World. Fluoxetine-HCl has been found 0.012 μg/L in surface waters and in the dose range of 0.54-0.929 μg/L in wastewater (Sehonova et al., 2018). In line with this information, 0.1 μg / L and 1 μg / L Fluoxetine-HCl was administered to swordtails. At the end of 96 hours, heart and liver tissues of the fish were dissected under antiseptic conditions and homogenized. Later, malondialdehyde (MDA), total glutathione (GSH), catalase (CAT) enzyme activity, superoxide dismutase (SOD) enzyme activity and total protein amount were determined by spectrophotometric methods. As a result, while CAT enzyme activity and MDA level decreased in heart tissue, SOD enzyme activity and GSH level increased. In liver tissue, while CAT enzyme activity and GSH amount increased, SOD enzyme activity and MDA level decreased. As a result of the comparisons with the control group, it was determined that Fluoxetine-HCl is effective in regulating the stress response by affecting the stress pathways in swordtails.
