Abstract
A 10 weeks growth experiment was conducted to determine the effects of dietary vitamin C, E and highly unsaturated fatty acid on growth and survival of goldfish (carassius auratus) with initial weight of 0.69±0.12 gr. They were fed with ten experimental diets having different level of vitamin E (50, 100, 1000 mg kg diet-1), C (100, 1000 mg kg diet-1), HUFA (highly unsaturated fatty acid): the test treatments were as follow: C100+E1000-HUFA, C1000+HUFA, C100+HUFA, C100+E1000+HUFA, E100+HUFA, E50+HUFA, C1000-HUFA, C100+HUFA,-C-E+HUFA,-C-E-HUFA. Final weight, specific growth rate, feed conversion rate and condition factor were evaluated at the end of experimental period. Final weight, specific growth rate were higher in fish fed the diet with C100+E1000+HUFA. The lowest final weight and specific growth rate were observed in-C –E-HUFA.Whereas food conversion rate (FCR) and condition factor (K) were not significantly different between groups. These results indicate that the diet with C100+E1000+ HUFA can effect some factors growth in goldfish, Carassius auratus.
