Abstract

Planktons are well known for their abundance in the water column but their dynamic population has been less studied especially on a temporal basis. Coral reef ecosystems in Pulau Bidong and Pulau Karah were chosen as the sampling point to study the mesozooplankton monsoonal distribution during the two main monsoons in the South China Sea the southwest and the northeast together with their respective pre- and postseason. The usage of 200-micron mesh size plankton net for this study was intended to expand the tropical knowledge that would focus on smaller zooplankton net mesh size. Mesozooplankton bloom was onset on pre-southwest peaked in density during postsouthwest monsoon and showed a significant fluctuation pattern compared to northeast monsoons series. Seven mesozooplankton phylum was identified and Arthropoda with its predominant class Crustacea was the most abundant organisms in the sampling area. Copepoda community which dominated the water column consist of Copepodite (juvenile) Calanoida Cyclopoida Poecilostamatoida and Harpacticoida. Larvae from phylum Echinodermata showed a post-southwest monsoon preference which was then recognized as its spawning season. Station 2 (north Pulau Bidong N05 37.809; E103 03.963) and station 3 (east Pulau Bidong N05 37.497; E103 04.193) were highlighted for their significantly high mesozooplankton density while Station 1 the UMTs Research Station (west Pulau Bidong N05 37.299; E103 03.827) and station 5 (south Pulau Bidong N05 36.580; E103 03.963) were deemed important as a ground for marine productivity. Findings from this study could contribute to the establishment of baseline information for the ecological dynamics of mesozooplankton about the coral reefs ecosystem resilience in Bidong Archipelago.
