E2 has a complex effects on the liver, female reproduction, sexual development and other organs. On the other hand, estrogenic compounds are also present in the aquatic environment by domestic waste and can adversely affect on aquatic organisms. The present study is aimed to investigate the effects of the injected E2 in a short period on the total weight, liver weight, gonad weight, hepatosomatic index (HSI), gonadosomatic index (GSI), plasma total protein, and vitellogenin (Vtg) levels on Chalcalburnus tarichi. It was found that the injected E2 caused an increase in all the measured values. However, only the liver weight, HSI, plasma total protein, and Vtg levels were found to be statistically significant (P}, number={2}, publisher={Van Yüzüncü Yıl Üniversitesi}
