The limnological fauna and flora of the garden pond of Prince Akishinonomiya Residence in the Akasaka Imperial Gardens, Tokyo, were investigated on July 22, 2004. The species are referred to 133 species of 76 genera. This pond is small in scale, but excellent as biota for microscopic organisms, with many kinds of water plants. There is no dominant species in animals, but Brachionus forficula of the Rotatoria is rather prominent and followed by Testudinella patina of the Rotatoria, Centropyxis hirsute and Arcella discoides of the Protozoa, and in plants Microcystis firma of the Cyanophyceae is dominant and followed by Chroococcus disperses of the Cyanophyceae, Coelastrum cambricum, Pediastrum boryanum and Dicty-osphaerium pulchellum of the Chlorophyceae, and Fragilari a construens of the Bacillariophyceae. Consulting Tanaka (1992), the fauna is referred to the type XI (mesotrophic rotiferal community) or the type XII (eutrophic rhyzopodean community), and the flora may belong to the type XI (eutrophic cyanophyceaean community).
