Abstract
The preliminary survey of the Project “Species diversity and genetic resources assessment of the genus Caulerpa (Caulerpaceae, Chlorophyta) in Thailand for the principal conservation and sustainable utilization” was kicked off in Trat Province as representative of the upper part of the Gulf of Thailand. Caulerpa, some other seaweeds and seagrasses were sampled mainly by scuba diving in the area of Ko Kut, Ko Chang, and nearby islands, totaling ten sampling sites from 19–23 December 2022. Unfortunately, it seems like December is not the right season for Caulerpa sampling, hence, not many Caulerpa were found. Ko Kradad, Ko Khai Hua Ro, and Ko Mak were the only three sites that Caulerpa could be collected. Based on morphological characters solely, at least four Caulerpa species were identified. For better precision of species diversity in the genus Caulerpa in these areas, twenty Caulerpa voucher specimens were prepared, and twelve of them were sent for DNA extraction and molecular analysis. The molecular results are pending.
