Cobia (Rachycentron canadum) is a coastal pelagic fish that has a rapid growth rate. The fish was expected a candidate for aquaculture development. The limitation of tank culture may effect growth, therefore information for rearing system in different culture densities for growth and survival of fishes is needed. The purpose of the experiment was to know the ideal density for the growth of cobia juvenile reared in circulation system. Juvenile of cobia 5 months old reared in polycarbonate tank with volume of 4 m3 with various densities: (A) 50 fishes/tank; (B) 100 fishes/tank; (C) 150 fishes/tank and (D) 200 fishes/tank with total length 33,04
