ABSTRACT
This study was conducted to investigate the effects of starvation for 8 days on the serum metabolites and antioxidant enzymes, thiobarbituric acid reacting substance levels, endogenous reserves in liver and muscle tissues of rainbow trout (Oncorhynchus mykiss). Eight-days of fasting caused a significant decrease in glucose, total protein, triglyceride, cholesterol, high-density lipoprotein and low-density lipoprotein levels as well as protein and lipid reserves in liver and muscle tissue of fish (p<0.05). The fasting period had no significant effect on the hepatic thiobarbituric acid reactive substances (TBARS), but, it caused a significant decrease in the hepatic catalase and glutathione peroxidase (p<0.05). In muscle tissue, the TBARS levels were significantly decreased (p<0.05). Whereas, antioxidant enzyme activities remained unchanged (p>0.05). The results obtained from this study showed that the short-term starvation leads to significant changes on serum metabolites, antioxidant enyzme activities and endogenous reserves of rainbow trout.
