Description 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.
