Abstract
Sustainability cultivation and management of sea urchin is an important effort to maintain the marine biological resources. Conservation and cultivation should be done ex-situ through education in universities. Purpose of this research is to determine sea urchin stages of cultivation in the laboratory and of embryonic development stages of Salmachis sphaeroides. The cultivation method consists of five stages: preparation of feed, taking sea urchin in natural habitats, spawning and fertilization, maintenance and enlargement of larvae. Spawning method is doing by natural stimulating, is raising slowly temperature and sea water adding. Salmachis sphaeroides was taken from Senggora, Pangkalanbun and cultured in a laboratory of one of university Palangkaraya. This research has of sea urchin is a good early models organism development, because of spawning can be one naturally and the stages of development the faster and simple and of embryonic development stages it is easy to observe. The success of sea urchin cultivation, because an attention to external factors, such as temperature, salinity, feed and sea water filter. The results of this study can be used as a reference for sea urchin cultivation ex-situ in laboratory and a very helpful for understanding early models of organism.
