Milkfish, Chanos chanos is one of economically important fish whose population is almost scattered in the waters of Indonesia. The study was conducted in Pejarakan ponds, Pejarakan village , Buleleng regency, Bali. Pond size used ± 14,200 m2 separated net into 4 plots; each plots ± 2350 m2. Weight of the fish used ± 806 g. Stocking density 165 ind./plot. The feeding treatment A = commercial pellet + vegetable oils; Treatment B = commercial pellet + fish oil. The feeding of fish during maintenance broodstock with frequency of 3 times/day as much as 3% / day. The result of observation that the activity of observed growth of broodstock milkfish, Chanos chanos in ponds by treatment A produces: body length: 52.36 ± 0.19 cm; weight: 1595.32 ± 52.36 (g); B = body length: 53.27 ± 0.11 (cm), body weight: 1709.4 ± 246.27 (g). The data result showed that treatment B of growth of length and weight are good when compared with treatment A; later from the analysis of the fatty acid content of DHA treatment B has a content of 3.72% when compared to treatment A is 2.86%. Research purposes to obtained data and information milkfish broodstock production through of vegetable oils and fish oils addition in feed formulation.
