In this study, Garra rufa Heckel, 1843 (popularly known as doctor fishes), which is a fatty fish species living in Kangal BalÃ?Â±klÃ?Â± Çermik Thermal Hot Springs and TopardÃ?Â±ç Stream mixing with these hot spring waters, was investigated. Hema-tological and non-specific immune parameters were investi-gated by comparing each environment in terms of seasons and each season in terms of environments. The amount of eryth-rocyte (RBC) and leukocyte (WBC) in the stream was found to be increased in summer and decreased in winter. On the other hand, no seasonal differences were observed in the pools due to the thermal water. Hb, Hct, monocyte, neutro-phil, phagocytic activity values were found to be low in the winters and high in the summers in the stream whereas no changes were observed in the pools. No difference was found between seasons and environments in terms of the amount of eosinophil cells. Lymphocyte and MCV levels in the stream were found to be increased in winter and decreased in sum-mer. No change was observed in the pools. Seasonal and en-vironmental no difference was observed in MCH values of both pools and the stream, whereas MCHC values in the stream were found to be high in summer and low in winter. In the research, differences in winter and summer seasons and effects of different environments in these values were inves-tigated.
