Abstract

Substrate materials for oyster and mussel may be used as spat collectors. Generally, spat occurrence is associated with salinity. Fluctuation of temperature during rainy season also triggers spat occurrence. It has been observed that Crassostrea iredalei and S. tuberculata (both tropical oysters) spawn 15 hours after lowering of temperature from 28 to 24°C, implying that temperature drop may be a stimulus for spat occurrence. Direct effect of salinity alone is not very clear but experts reported that tropical bivalves have been induced to spawn in 3 to 5 days by lowering salinity from 34 to 24 ppt.
