Major constrain in the pearl oyster breeding that are lowest of growth and development of larvae to spat and also low survival rate. One of the affected factors its unknown the optimum of rearing environment conditions, such as temperature, salinity, dissolved oxygen and light intensity. The objective of this research was to determine feeding activity, levels of food consumption, types and correct density of feed for optimizing of larvae growth and development of spat so that obtained high survival rate. This research consisted of four levels experiments, which are the study of larvae rearing in laboratory, spat rearing in laboratory, rearing of larvae and spat under optimum environment condition and study of spat rearing in the sea. Factorial completely randomized design was applied to know that effect of types and feed density, physiology response of larvae and spat to the levels of temperature and salinity. Completely randomized design was applied to the study of response of larvae and spat to the levels of light intensity. Randomized block design was applied to the study of spat in natural sea waters.
