Calculating the Contribution of Zooxanthellae to Giant Clams Respiration Energy Requirements
Giant clams (Tridacnidae) are known to live in association with photosynthetic single cell dinoflagellate
algae commonly called zooxanthellae. These algae which can be found in the mantle of the clams are
capable of transferring part of their photosynthates which become an important source of energy to the
host ( apart from filter feeding activity). In order to understand the basic biological processes of the
giant clams , the contribution of zooxanthellae to the clam’s energy requirement need to be determined.
This review describes how to calculate the contribution of zooxanthellae to the giant clam’s energy
requirement for the respiration process.
