Species Diversity of Plankton in Suan Sunandha Rajabhat University, Samut Songkhram Campus
Keywords:Species diversity, Plankton, Samut Songkhram
The study of phytoplankton and zooplankton in Suan Sunandha Rajabhat University, Samut Songkram Campus by collecting the samples following the seasons: the cool season (December, 2012), the hot season (March, 2013) and the rainy season (June, 2013). The plankton samples were collected from 5 stations by using 70 micrometers mesh size of plankton net and examined the water quality.
The results showed that, in total, there are plankton in 48 genera, 77 species which consist of 36 genera, 58 species of the phytoplankton, and 12 genera, 19 species of the zooplankton. The phytoplankton: Class Bacillariophyceae was the dominant
group and the most diverse was the genus Chaetoceros (8 species). The zooplankton: Phylum Sarcomastigophora had the most species diversity and most diverse zooplankton was the genus Ceratium (5 species). The cool season was the season when the greatest species diversity of the plankton could be found and the water temperature average was 27.79 ° C. The pH average was 7.82. The dissolved oxygen average was 6.21 mg/l. The salinity average was 24 ppt. These conditions are the appropriate environment for these living aquatic organisms.
