Zusammenfassung:Nile tilapia is one of the main fish species cultivated in the World. However, there are few studies evaluating the effects of stunning methods on the stress of this fish. The aim of this study was to evaluate the effect of electrical stunning (ES), CO sub(2) narcosis (CN), and iced water (IW) on indicators of stress in tilapia, e.g., muscle adenosine triphosphate (ATP), enzymatic antioxidants (catalase, lactate dehydrogenase and glutathione reductase) and plasma cortisol. The muscle ATP was highest (P
