Description
Summary:Harmful Algal Blooms (HABs) is not negligible as their occurrence poses threat to human health, ecosystem and environmental deterioration, as well as negative implications to the aquaculture and fisheries economy. Phytoplankton dynamic in tropical countries, especially in conjunction with physicochemical influences to the production and growth of phytoplankton species are still poorly understood. In this study, qualitative and quantitative samples of phytoplankton were obtained from October 2012 to March 2013. Macronutrients especially silicate showed to have direct impact on cell density trend, while in-situ parameters showed weak relation to cell density with exception to Secchi depth.Cell density was also affected by fluctuations of nutrients with northeast monsoon (NEM) that influence precipitation and upwelling in the west coast of Sarawak. A total of 61 taxa of phytoplankton was identified to the generic level, with 41 diatoms (18 pennate and 23 centric), 17 dinoflagellates, 1 silicoflagellates and 2 cyanobacteria.
