Plankton community in mangrove estuary at Khao Kao canal, Phang-nga Bay was studied in September 1990 (wet season) and April 1991 (dry season). A diatom, Chaetoceros, was the dominant taxon in both wet and dry season. More genera (38) of phytoplankton were found in the dry season compared to the wet season (22). The total number of cells per cubic meter were also greater in the dry season. Nine phyla of zooplankton were observed in Khao kao Canal. Adult copepods were often found in both seasons. Tintinnids were more common in dry season. Gastropod and pelecypod larvae were found throughout the canal. Post larvae of shrimps Penaeus monodon, P. semisulcatus and P. merguiensis were abundant around mangrove roots near the banks, especially after sunset. The diversity and abundance of plankton were higher during high tide compared to low tide. These observations suggest that this mangrove estuary is an important nursery ground.
