The preliminary study on the rearing of carp broodstock in aquarium using recirculation system was conducted in a period about 9 weeks. Carp broodstock were stocked in 63 l glass aquaria filled with 53 l water at a rate 2 fish per aquarium. They were fed diet containing 35 percent protein and 7,5 percent lipid at a rate of 3 percent of the total body weight daily. The result showed that the broodstock spawned naturally 44-63 days after being reared in aquarium. The weight of eggs about 130-180 gram. The water quality was good enough for normal life of fish where the dissolved oxygen content was 4,0-8,3 ppm and NH3 content was 0,18-0,68 ppm.
