Effects of Anesthesia on the Cortisol, Glucose and Some Blood Electrolite Levels of the Juvenil Rainbow Trout (Oncorhynchus mykiss, W. 1792)

In this study, the effect of the anesthesia on the cortisol levels and glucose in the plasm in addition to sodium (na), calcium (ca), potassium (k) and chloride (cl) levels in the serum of rainbow trout juvenil of was investigated. cortisol, glucose, na, ca, k and cl values in the blood samples of fishes which were applied anesthesia and not applied anesthesia were determined and the values were compared as statistically. it was found that the cortisol and glucose levels of the groups which were applied anesthesia significantly increased compared to control group as statistically (p<0.05) but na and k levels significantly reduced compared to control group (p<0.05). additionally, it was determined that the ca and cl values of both groups are close to each other and between them there is no significant different (p>0.05).
