This research, "A Study of Plankton Biodiversity in the Water Resources of Sa Nae Daeng Pond,
Somdet Phra Srinagarindra 95 Public Park (Khao Pae Choi), Na Ta Luang Subdistrict, Mueang Trang District,
Trang Province," aims to investigate the biodiversity of plankton in the water resources of Sa Nae Daeng
Pond. The study examines water temperature, pH, dissolved oxygen (DO), cloud types, relative humidity,
and air temperature.
The water quality study of Sa Nae Daeng Pond revealed an average water pH of 8, an average water
temperature of 28.25°C, a dissolved oxygen (DO) range of 5.25 mg/l, and an average water transparency of
0.32 m. The average air temperature was 32.8°C, the average humidity was 51.95%, and the most
prevalent cloud type was Cirrus, followed by Cumulus. The plankton biodiversity study identified 10
species of zooplankton, including Dugesia spp., Ephemeroporus barroisi, Rotifer sp., Paramecium sp.,
Spirulina sp., Neidium productum, Phacus sp., Strongyloides stercoralis, Oscillatoria sp., and Odonata sp.
Three species of phytoplankton were identified : Micrasterias furcata, Closterium sp., and Arcella
discoides Ehr.
