Abstract

Cobia is potential fish culture, because has characteristic fast growth.The purpose of this research is observe feed formulation to growth and survival rate of cobia on floating cages. This research was conducted at floating cages of marine culture fisheries Lampung on September until Desember 2017. The research using three treatments and three replication. The Treatments feed is commersial feed with 37% protein level (P0) as a control, formulation feed with 37%protein level (P1) and formulation feed with 35% protein level (P2). The result of this research showed that the absolute growth of weight 227.6 g, length 8.87 cm, protein retention 16.80% and survival rate 77%, the best feed in P0 with total feed consumption 719.71 g and feed convertion 3.02. Water quality during research were still optimum for fish culture except ammonia. pH 7.77-8.3, dissolved oxygen 5.03-6.81 mg.L-1, temperature 29.5-30.5 °C, salinity 32-33 ppt, ammonia 0.118-0.599 mg.L-1, depth 19-19.3 m and brightness 6-9 m.
