UJI PLAGIASI : The survival and growth rate of three species of sea anemones from asexsual reproduction in pulau kerumputan and pulau karayaan, Indonesia

Abstract

A sea anemone is one kind of marine biota which habitat is found in the coral reef area. Sea anemones havequite high ecological and economical value. Currently, the population keeps on being degraded due to thehigh intensity of fish catching to meet the demand from domestic market and exports. Therefore, it isnecessary of having restocking efforts and environment-friendly aquaculture using the seeds of asexualreproduction results in the hatchery. The purpose of this study is to find out the survival and growth rateof three species of sea anemones, namely Stichodactyla gigantea, Entacmaea quadricolor, and Macrodactyladoreensis 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 anemonewith longitudinal body cleavage techniques, from all three parents. The results showed that asexualtechnology of seeds reproduction are able to produce the survival and growth rate quite well when theyare cultivated in natural water. The three species of anemones had different survival and growth rate. Theanemones, 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 amongcultivation sites had no difference at all species of anemones
