Abstract
Study on Species Diversity of Phytoplankton and Correlation Between with Phytoplankton in Green Mussels farm area at Bang Ta boon Bay, Phetchaburi Province was conducted during a rainy period (November, 2016). The results showed that a total of 35 phytoplankton species. The highest number of phytoplankton was found in dinoflagellates and diatom are the most species diversity. The dominant species are Cyclotella sp. , Coscinodiscus sp. , Oscillatoria sp. and Ceratium furca . The index of species diversity ,richness index and evenness index of phytoplankton were 0.34 , 0.098 and 3.56 respectively. Average water quality of seawater in the coastal area of Bang Ta boon Bay was still in the standard, except for phosphate and ammonium. The analysis of the correlation between water quality and phytoplankton was found that phytoplankton on the Bang Ta Boon bay had a moderate correlation with ammonium. Correlation with other factors, Calcium silicate had the positive significant at 0.01 level with phosphate content and the negative significant at 0.05 level with pH.
