Increased 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).
