Caluya Island has 8 Barangays and in Barangay Poblacion, where the municipality Hall is located, in 2008 has enacted a public ordinance to convert 15% (5 hectares) of its coastal area as a protected marine sanctuary. DENR in CENR office in Culasi and Caluya Municipality have asked for the technical assistance of PSDCF to establish this sanctuary. Caluya Island is an elongated island that stretches from north to south. It is approximately 7.3kms long and 4.7kms at its widest point. See maps below of where Caluya Island is in the Philipines, map of Caluya and a map of the precise location of the Caluya marine sanctuary in Barangay Poblacion. This area was initially identified by a local fisherman as a feeding ground of sea turtles and when PSDCF has done a preliminary visual underwater observation and sonar analysis of the area, the coral reefs was found to be in excellent condition.
