The climate of Gulf of Kachchh, India is dry and has low rainfall, high
salinity, temperature and tidal amplitude.
The average annual rainfall is about 400mm.
Tidal amplitude varies from 3.0 to 6.0 meter.
Surface salinities vary from 35.2 to 39.4 ppt.
The water temperature exceeds 35 degree centigrade in extreme summer and
drops below 15 in extreme winter.
Hence, Low salinity may not be the key factor in determining the
occurrence of Pseudosiderastrea tayami Yabe and Sugiyama, 1935

In Indonesia, relatively dense populations of Pseudosiderastrea tayami Yabe
and Sugiyama, 1935
may co-occur with abundant Oulastrea crispata (Lamarck, 1816) corals.
This this is likely the case on reefs near river outlets with much
siltation (e.g. in Jakarta Bay, off Jakarta, and in the Makassar Strait
off Makassar). However, there are also reefs with freshwater inflow (e.g.
at Tulamben, Bali) where both species can be found in very clear water.
Siltation may not be the key-factor determining the occurrence of these
species, but low salinity.

Dear All,
Recently I surveyed the coral reefs of Gulf of Kachchh, India.
During my survey I observed that the coral Pseudosiderastrea tayami Yabe
and Sugiyama, 1935 was commonly distributed in shallow areas near
mangroves where the silting rate was very high. I would like to know "
Which coral species in the world has high survival rate in muddy
environment?"
Kind regards,
R. Jeyabaskaran
