This research was conducted to determine the effect of lime (CaCO3) concentration on the availability of calcium in water and growth of Crayfish (Cherax quadricarinatus). Completely random design was used in the experiment that consisted of 4 treatments and 3 replications. Four treatments of lime concentration were 0, 50, 100, and 150 mg CaCO3/l. The research was conducted in Fisheries Research Station, Agriculture Faculty, Gadjah Mada University for 30 days. Ten Crayfish were reared in 60 cm x 40 cm x 50 cm aquarium in 60 l water. Crayfish were fed ad libitum with Tubifex tubifex. Calcium concentration on water, Crayfish growth, and water quality were observed every tenth days. The data of calcium concentration on water and Crayfish growth were analyzed with regression and correlation analysis at 95% confi dence level, whereas water quality analyzed descriptively. The research showed that there was correlation between lime concentration and its availability in the water. It showed that, more lime concentration resulted on higher calcium availability in water. Crayfish growth was relative faster on higher lime concentration.
