Caulerpa species, collectively known as “sea grapes”, are widely cultivated and harvested in the Philippines. This study identified Caulerpa species from Coron, Northern Palawan based upon their morphology, and described for the first time the current status of Caulerpa harvesting in the municipality through a social survey. In Coron, it is suggested that the supply is adequate for their local market demand given the current harvesting methods. The possibilities of phycoculture of sea grapes have also been explored but, at present, with only limited success. This study revealed that Caulerpa is still regarded as an economically important crop that provides income and livelihood to the Calamian archipelago and has the potential to be cultivated for sustainable production and use.
