Abstract: From October 2012 to February 2014,we carried out the transplant experiment of Tubastraea coccinea in Tongan Bay,Xiamen.After collecting 11 stony coral samples from Taishan Islands sea area in Fuding,we had monthly observations of coral survival,morphology,growth and the ecological factors including water temperature,salinity,turbidity etc,and analyzed the relationship between coral growth,survival and ecological factors by temperature,salt depth turbidity profiler and Vernier calipers as well as other tools.The results showed that,during the observation period,the sea water temperature was 15.27~30.11℃,the salinity was 21.98~30.35,and the turbidity was 2.91~50.31 FTU;the changes of water temperature and turbidity did not cause coral bleaching and death;due to the increase of the amount of water in the sea during storm,the salinity was decreased significantly,and when the salinity dropped below 28,the coral began to turn white,and after a period of time,the coral was severely white and then died.During the transplantation experiments,Tubastraea coccinea had an average growth rate of about 8.2 mm/a.In addition,due to the enrichment of attached marine organisms in Tongan Bay,the transplanted coral samples were attached to a large number of algae,shellfish and other organisms which inhibited coral growth and seriously caused coral death.In summary,the experimental results showed that,mainly due to the salinity and attachment of biological organisms,Tubastraea coccinea couldnt survive and grow in Tongan Bay sea area.
