Pillai, C S G and Nair, P V Ramachandran (1972) Productivity studies on some hermatypic corals by means of both oxygen measurements and 14 C method. In: Proceedings of the First International Symposium on Corals and Coral Reefs, Marine Biological Association of India, Mandapam Camp, India, 12-16 January 1969, Mandapam.
The hennatypic corals harbaur boring filamentous. alpe in their skeleton as well as symbiotic zooxanthellae in their soft tissue. These imprisoned algae produce much more quantity of oxygen by photosynthesis than the respiratory needs of the coral. Various attempts have been made in the past to. estimate the oxygen production of corals and there was apparently disagreement among authors on the role of boring algae in the total production. In this work an attempt is made to evaluate the percentage of oxygen production contributed by the boring algae and the symbionts of a few species of reef building stony corals. from Palk Bay and Gulf of Mannar around hlandapam (S. India). The gross production was estimated by dark and light bottles by Winkler technique, converting the oxygen values into carbon equivalents. The share of zooxanthellae was then determined by incubating the isolated symbionts with NaH14CO3. A marked difference was observed in the two sets of values thus obtained. In the light of the present results the role of the boring algae in the productivity of reef corals is discussed.
