| Summary: | Coral bleaching was investigated in the coral reefs of Sta. Ana Calatagan
in Batangas and have been set the date during summer. There are three points in
Calatagan bay where every point has 100 meter away from the seashore. When
gathering data, there are three physical parameter to used such us temperature,
salinity and pH. The method that used in this study to count the coral is the lines
intercept method. Photo documentation is also need to this study in order to see
the corals who intercept the line by using the field tape measure.
A total of 83 coral specimens falling under six families were counted,
which translates to a live coral cover of 2.69%. Bleached live coral cover was
calculated to be at 2.69%. Average values for temperature were found to be
slightly above the upper limit of 30°C, while average salinity values fall slightly
below the ideal range of 32% to 40%. These measurements indicate elevated
temperatures and reduced salinity respectively, and we concluded to account for
the occurrence of bleaching in the study site. |
