| Abstract: | A
survey on bleaching and the secondary threats on bleached corals in the
selected sites of Palk-Bay were conducted during May and June 2010. Massive
corals represented by the genera Porites,
Goniopora, Favia were bleached extensively. Significant portion of the
surface of live corals were found dead. Coral recovery after bleaching was at a
great risk due to the algal overgrowth and sedimentation which would lead to
their death and permanent loss. Destruction of the slow growing corals by natural
and altered environmental conditions warrant the proactive conservation
approach guided by scientific principles. Current conservation methods in India offers
physical protection to corals by entry restriction and a ban on collection of
corals under wild life act. This is inadequate as they could not prevent
secondary stressors taking toll on corals during environmentally induced stress
conditions. |
