The objective of this research was to know the growth and survival rate of redclaw crayfish (Cherax quadricarinatus) reared in recirculation system with density 20, 30, 40 and 50 m-2. Lobster with 6.02 ± 0.13 cm length and 6.23 ± 0.51 gram initial body weights were cultured in 60 x 30 x 40 cm aquarium and compiled in recirculation system, for 42 days. Result of research showed that there are statistically difference at growth rate daily weight, coefficient of variances and feed efficiency (p<0.05). No significantly differences in absolute length growth and survival rate were observed (p>0.05). From this research it can be concluded that the best density for freshwater crayfish (Cherax quadricarinatus) was 50 m-2.
