Abstract
After the oil spill incident in Rayong, Thailand in 2013, it was recognized that information on the toxicity and other effects of dispersed oil on reef organisms, and corals in particular, was very limited. This study examined the effects of the oil spill on gonadal maturation of reef corals in Rayong. We repeatedly sampled colonies of six coral taxa (Favia spp., Favites spp., Goniastrea spp., Platygyra spp., Symphyllia spp. and Porites spp.) at impacted and control sites during October 2013 and March 2014. The results showed no significant difference in gonadal development between impacted and control sites. However, we found that Porites spp. was very sensitive to the oil spill, and they responded by producing large amounts of mucus, with some colonies losing zooxanthellae and being bleached. The histological study revealed that most colonies contained oocytes and spermaries at stages II – IV both in October 2013 and March 2014. Long term monitoring at these sites should be done to monitor for chronic effects, and that data should include the average number of ovaria per colony and oocyte diameter from impacted sites compared to control sites.
