As a result of the study, seasonal changes in ACTH and cortisol levels were found statistically significant (p <0.05). It was suggested that ACTH and cortisol levels may increase due to reproductive activities in spring and rising water temperature in summer. It was concluded that animals have physiologically adaptive arrangements on the hypothalamic-pituitary-interrenal (HPI) axis to overcome stress and survive.eninfo:eu-repo/semantics/closedAccessCyprinus CarpioACTHCortisolSeasonArticle3011A1210712110N/A
