There are five stages in the cultivation of starfish, namely: spawning (spawning of adult) fertilization of the egg (egg fertilization) Raising larvae (larval culture) Maintenance (settlement) Enlargement (growout) Stock fertilized eggs in the summer will produce larvae with good quality , Larvae will be cultivated in the cultivation container in the form of a parabolic tank with a source of air at one point. The sea water is set at a temperature great 5 of 28 C and salinity of 32 ppt. Larvae feed in the form of phytoplankton culture Dunaliella tertiolecta and Phaeodactylum tricornutum with a density of 5000-10000 cells / ml.

The picture above is a submersible culture chambers that are used to store a sea star larvae. This chamber is placed in sea water at a depth of 5-15 m, cahmber is equipped with a battery voltage of 12 V gel cell. Larvae will be included on each bottle and will metamorphose into brachiolaria within 12 days. Larvae feed in the form of Dunaliella great 5 primolecta and Phaeodactylum tricornutum.

BENEFITS Starfish STARFISH often considered detrimental because it is a predatory animal. great 5 Increasing the abundance of sea stars because it has no economic value so that the exploitation factor is very low.
ECOLOGICAL VALUE bioindikator level of diversity of animals, especially those living in areas of coral reefs. Starfish species, becoming the main predator in the ecosystem of the rocky coast. The specific blue oyster population control so that other species may inhabit the coast and the bivalves do not dominate excessively.
ECONOMIC VALUE The research team from the Scottish Association for Marine Science studying the substance / slimy substance that coats the spiny starfish body. Recent studies that starfish can become a drug for asthma and arthritis / arthritis. Inflammatory diseases such as asthma and arthritis is a condition that occurs when the body's natural great 5 response to infection à accelerated beyond the control of the white blood cells (leukocytes) began to accumulate in the blood vessels and attached to the side-sisinyaà great 5 tissue damage. Mucus starfish can be used to coat the blood vessels that would allow white blood cells to flow easily.

Only certain types in the Indonesian archipelago. Starfish cut and squeezed out black liquid, then soaked together tamarind leaves for 2 days and cooked with coconut milk (Georg Eberhard Rumpf). In Japan sold for food in the dry state. great 5 (Wikipedia.org) Materials research
