Abstract

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.
