Abstract

The role of essential fatty acids  as a precursor of prostaglandin and as a component of cell membrane in the form of phospholipids, can affect cell fluidity. Vitamin E functions as  fatty acid antioxidant in the body and affects egg quality.  Vitamin E and essential fatty acids (n-3 and n-6) are required at the same time in a proper  ratio to induce fish gonad maturation.  Zebra fish Danio rerio broodstock in 29 days pre-saline were fed on diet containing 4 different vitamin E concentration; i.e. 325, 375, 425 and 475 mg/kg diet with constant n-3 and n-6 fatty acid doses of 1% and 2%, respectively, for 6 weeks.  Reproduction performance in terms of fecundity was improved (p<0.05), whilst gonado somatic index, gonado somatic index saline, fertilization rate, hatching rate, survival rate, yolk absorption rate and daily growth rate were insignificantly different.

  ABSTRAK

Asam lemak esensial berperan sebagai prekursor prostaglandin dan sebagai fosfolipid pada membran sel yang dapat mempengaruhi fluiditasnya. Sedangkan vitamin E berperan  sebagai antioksidan asam lemak dalam tubuh sehingga berpengaruh terhadap kualitas telur yang dihasilkan. Vitamin E dan asam lemak  essensial (n-3 dan n-6) dibutuhkan secara bersamaan dengan kombinasi perbandingan yang tepat untuk pematangan gonad ikan. Induk ikan yang digunakan dalam penelitian ini adalah ikan zebra Danio rerio yang berumur 29 hari pra salin dan dipelihara selama 6 minggu dengan pakan mengandung kadar vitamin E yang berbeda yaitu 325, 375, 425, dan 475 mg/kg pakan pada kadar asam lemak n-3 (1%) dan n-6 (2 %) tetap. Penampilan reproduksi pra salin ikan tersebut hanya berpengaruh nyata terhadap fekunditas namun tidak berpengaruh nyata terhadap gonado somatik indek, gonado somatik indek salin, derajat pembuahan telur, derajat tetas telur, kelangsungan hidup larva, laju penyerapan kuning telur dan laju pertumbuhan harian.
