ncreased environmental pollution can be attributed to a variety of factors resulting from different industrial and agricultural
activities. In fish, pollutants can be captured from various sources including the persistent contaminants of agricultural
origin. Such pollutants can seriously affect the aquatic organisms by inducing the oxidative stress through the generation of
extremely harmful substances known as free radicals. Exposure to stress and diseases and resulting losses are among the major
constraints in the aquaculture business, and even more so in intensive production such as re-circulating aquaculture system
(RAS). Thus diseases are a major cause for morbidity and mortality, causing substantial financial economic losses. However,
one of the most promising methods of oxidative stress and diseases control in aquaculture is the strengthening of defense
mechanisms in fish through prophylactic administration of immunostimulants. On the other hand, antioxidants such as the
flavonoids are agents that inhibit or neutralize these free radicals. Flavonoids are naturally occurring polyphenolic compounds
in plants of positive effects on human health. In this study, we investigated the influence of incorporation of some natural
antioxidants in fish feed on the oxidative stress induced by the aquaculture pesticide cypermethrin which promote severe tissue
injury in Redbelly tilapia (Tilapia zillii) reared in mega flow re-circulating aquaculture system (RAS).
