Black-lip oyster, Pinctada margaritifera (Linnaeus, 1758) with high nutritional value has been considered in the study of growth characteristics. Temperature factor by effect on the physiological functions such as the rates of respiration, clearance and excretion and absorption efficiency play key role in the metabolism and energy balance. SFG (scope for growth) is a physiological index; which reflects health status and the ability of adaptive responses of individuals to natural environments quality changes, particularly temperature and food. When this balance is positive, the organism has matter or energy available for growth, biomass and reproduction. This study was conducted at the pre-monsoon, winter monsoon season and post-monsoon climatological periods in Chabahar Bay, Oman sea under laboratory conditions. In this experiment, SFG values was positive at temperatures ranging from 21°C to 28°C did observed at the post-monsoon significantly higher relative to the pre-monsoon. The results showed that Pinctada margaritifera grew better in less stress conditions after winter monsoon; that is manifest as an increase in SFG index. The STELLA model also shows that Chabahar Bay is a favorable habitat for Black-lip oyster farming.
