Treatment of vitamin E levesls were significant (p<0.05) different with respect to time ripe gonads, ovi somatic index, fecundity and egg diameter. Females exposed to 300 μg/kg feed of vitamin E can increased time matured gonads 67 days, somatic ovi index 14.95%, absolute fecundity 13547 eggs/spaw, relative fecundity 98 eggs/g gonado weight and egg diameter 1.16 mm. But hatching rate and time to hatching did not different between the treatments (p>0.05).enLabeobarbus festivusFeedVitamin EReproductionHatching rateArticle
