The study wasconducted from November 2018 to January 2019 at Center for BrackishwaterAquaculture in Ujong Batee, Aceh Besar District, Indonesia. The completelyrandomized design feed; 200 mg kg-1feed; 250 mg kg-1feed; 300 mg kg-1-1feed; 150 mg kgfeed; and 350 mg kgfeed.The seabass body weight ranges from 2 g to 4 g and total length ranges from 5 cm to7 cm with a stocking densities of 10 fish 10 liter-1. The fish fed at feeding 10% ofbody weight, twice daily at morning and evening. The result showed that the feedwith the addition of vitamin E had a significant effect on body weight gain, specificgrowth rate, feed convertion rasio, feed efficiency and sulvival rate -1of feed.Keyword : Seabass, Lates calcarifer, vitamin E, performance growth, sulvival rate,feed utilization-1-
