This study was conducted as long as six months from May ? October 2013; located at the soil ponds owned by the Hatchery Laboratory and fish breeding; University of Riau. The purpose of this study was to evaluate the best dose of Vit E added to fish pellets on egg quality of kelabau fish (Osteochilus kelabau) which includes: time for gonadal maturity achievement; ovisomatic index; laten time; number of ovulating eggs; maximum egg dimeter at the end of experiment; percentage of fertilized eggs; hatching rate and survival rate of larva. Applied doses of Vit E were 0; 100; 150; 200 mg/kg pellets. The results show that the best dose of VIT E to reach gonad maturity was 200 mg/kg pellets with three months cultivation period. Laten time was 13.5 hours and the average number of ovulated eggs were 4; 807. The ovisomati index was 0.82 % and the average diameter of eggs after treatments was o.14 mm. Fertilization rate was 0.61 %; with hatching rate was 16.68 %. Unfortunately; survival rate of larve was 0 % after 3 days old.
