Abstract
Oil spills potentially effect exposed organisms at various stage of life. This work aimed to access health risk of crude oil to larva development of a sessile organism the Black scar oyster Crassostrea iredalei by using water accommodate fraction (WAF) of crude oil. Male and female gametes was collect and fertilized to obtained larvae at cleavage stage. The larvae were then incubate in various concentrations of WAF (0, 6.25, 12.5, 25, 50, and 100 %). After 24 hour of exposure, normal D-shaped veliger larva (D-larva) was observe. The result showed that WAF crude oil affected the development and the successful of D-larva development. Severity of WAF effect was increasing with dosages of exposure. The abnormal larva developments were increasing in the high concentrations. The information obtaining from current work is important for health risk assessment of crude oil contamination incident in marine ecosystem. This study will also contribute valuable knowledge needed for aquaculture to know effect of crude oil spill to oyster farming area.
