A sea anemone is one kind of marine biota whose habitat is found in the coral reef area. Sea anemones have quite high ecological and economical value. Currently, the population keeps on being degraded due to the high intensity of fish catching to meet the demand from domestic market and exports. Therefore, it is necessary of undertake restocking efforts and environment-friendly aquaculture using the seeds of asexual reproduction results in the hatchery. The purpose of this study is to find out the survival and growth rate of three species of sea anemones, namely Stichodactyla gigantea, Entacmaea quadricolor, and Macrodactyla doreensis are cultured in the water of the islands of Kerumputan and Kerayaan, Indonesia, for 4 months, from June - September 2015. The seeds used are from the result of asexual reproduction of a sea anemone with longitudinal body cleavage techniques, from all three parents. The results showed that asexual technology of seeds reproduction are able to produce the survival and growth rate quite well when they are cultivated in natural water. The three species of anemones had different survival and growth rate. The anemones, S. gigantea and E. quadricolor, had the highest survival and growth rate, whereas anemone of M. doreensis had the lowest survival and growth rate. The survival and growth rate of anemones among cultivation sites had no difference at all species of anemones.
