Giant Clam Nurseries and Population Studies

Giant Clams are important regulators of the oligotrophic conditions that coral reefs need the thrive. They are
able to filter on average 1000 litres of water per day which controls the water quality and nutrient levels in the ecosystem. This reduction in nutrients by filter feeders allow corals to thrive.
During this course students will be introduce to different
survey techniques to monitor giant clams and be taught the
key processes to evaluate and recognise different species.
We will also demonstrate the steps required to manage giant
clam nurseries and the on-going maintenance and data
collection to be done following transplanting.
