|Issue Date:||2006||Abstract:||Most marine fish larvae require high amounts of n-3 HUFA (highly unsaturated fatty acids) such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (Watanabe, 1982; Izquierdo, 1996). Fish larvae tissue lipids are also very high in n-3 HUFA, what implies a higher risk of peroxidation (Sargent et al. 1999) and cellular damage (Kanazawa, 1991), requiring then antioxidants to protect them intra- and extra-cellularly from free radical compounds. Vitamin E (Vit E) functions as a chain breaking antioxidant, reacting with the lipid peroxide radical produced and preventing the further reaction with a new PUFA. Hence their requirements are related with the dietary and tissue PUFA contents. The objective of the present study was to determine the effect of dietary Vit E on gilthead sea bream and sea bass survival, growth and stress, at different n-3 HUFA levels.||URI:||http://hdl.handle.net/10553/5855||Source:||XII International Symposium on Fish Nutrition & Feeding, 28 May - 1 June 2006, Biarritz, France||Rights:||by-nc-nd|
