Abstract: In this study, we reported aquatic micro-organisms observed at Kado-ike pond, anirrigation pond in Numazu City, Shizuoka, in summer of 2006-2019. Kado-ike pond is aneutrophic pond and blue-green algae are blooming. In observation with microscope, 12 generaof unicellular prokaryotes, 70 genera of unicellular eukaryotes including 22 genera ofprotozoans, 18 genera of multicellular eukaryotes (metazoans), and 1 genus of a higher plant
were found. Some micro-organisms of Cyanophyceae, Bacillariophyceae, Chlorophyceae,
Oligohymenophorea, Lobosea, Rotatoria, and Branchiopoda were observed relatively frequently.
These communities of phytoplankters and zooplankters have been balanced with each otherand were thought to keep the ecosystem of this pond.
