The Effect of Rosehip (Rosa Canina L.) Plant Extract Application on Serum Acth, Cortisol and Aldosterone Hormone Levels of Carp (Cyprinus Carpio L.)

Abstract

In this study, Rosa canina L. plant extract was applied on carp at acute and sub-chronic durations in different periods (4 and 30 days) and at different doses (5, 10 and 20 ppm). After the application, adrenocorticotropic hormone (ACTH), cortisol and aldosterone hormone levels were determined in the serum. It was found out that there was a significant increase at ACTH level in 10 and 20 ppm groups at acute and in all dose groups at sub-chronic periods when compared to control group (p<0.05). It was found significant that cortisol hormone level decreased at acute period 10 and 20 ppm in dose groups but, in all dose groups at sub-chronic period cortisol level increased according to the control group (p<0.05). It was determined that aldosterone hormone levels increased significantly at acute period in all dose groups related to the control group and at sub-chronic period, it also increased at 10 and 20 ppm groups (p<0.05). Increasing of serum ACTH levels at acute and sub-chronic period and serum cortisol levels at sub-chronic period was thought as an adaptive organization towards to overcome the stress which caused by the application of rosehip extract on the fish.
