The present paper systematizes the results of the research on the effect of wheatgrass juice administration on some important indicators in assessing the physiological state of two summer-old Cyprinus carpio individuals coming from a recirculating system, as well as on some biochemical parameters with role in the antioxidant defensive. For this, an experiment was carried out over a period of 56 days, which consist in growth of 200 carp specimens, with an initial average weight of 72.85�1.79 g/specimen. Observations carried out during the entire monitoring period of the experimental variants emphasized a good sanitary status of the studied specimens, accompanied by an active feeding behavior. The results on the activity of oxidative stress enzymes and malon-dialdehyde concentration emphasized significant differences between the treated variants with wheatgrass juice and the control variant, closely related to the wheat juice concentration with which the food ration was supplemented.
