ABSTRACT
The purpose of this study was to determine the influence of some phytobiotics on oxidative stress at Oreochromis niloticus reared in a recirculating aquaculture system. The experimental variants were: V1-control, V2-1% rosemary (Rosmarinus officinalis)/kg feed, V3-1% sea buckthorn (Hippophae rhamnoides)/kg feed and V4-1% ginger (Zingiber officinale)/kg feed. Analysis of oxidative stress was performed by measuring the following indicators: reduced glutathione (GSH), lipid peroxidation (malondialdehyde-MDA) and total antioxidant capacity (TAC). The analyses were measured using the spectrophotometer SPECORD 210 Analytikjena, at the beginning and at the end of the experiment from the blood, plasma, muscle tissue, liver and gut. Regarding lipid peroxidation significant differences (p<0.05), in statistical terms, were recorded in plasma and gut level. Concerning the total antioxidant capacity significant differences (p<0.05) were recorded in plasma. Results obtained in determination of reduced glutathione from blood showed between initial and final experimental variants significant differences (p<0.05). At the end of experiment, it was observed a correlation between MDA and TAC in the gut level. In conclusion, based on the results from lipid peroxidation analysis, we can say that oxidative stress was reduced after administration of sea buckthorn in feed of Oreochromis niloticus species.
