The research has been conducted on the chub fish caught in Melendiz Stream (Aksaray) at different times (2010 - April, June, July, and November; 2011 - February and March). As a result of the hormonal analyses on blood serums, TT3 and TT4 levels have shown meaningful changes (p < 0.05) inversely proportional to the water temperature. It made us think that this change is due to adaptation decreased/increased metabolic (energy) activity provided by the fishes against temperature stress.eninfo:eu-repo/semantics/closedAccessSqualius cappadocicustriiodotironinethyroxineseasonArticle51580981410.1080/09291016.2019.15669872-s2.0-85060492490Q2WOS:000547524200014Q4
