Zooplankton samples were taken in the littoral zone (A area, northwest part； B area, northeast part) and the lake center of Lake Kizaki (surface 140ha; maximum depth 29.5m), Nagano, Japan, five times from August to November, 1983. There were found about 28 species of the Rotatoria in the A area, while in the B area, much larger biomass of the Copepoda was obtained and the Cladocera were more abundant (11 species). On the other hand, the dominant species in the lake center were Kellicottia longispina (Rotatoria) in number and Daphnia hyaline (Cladocera) in biomass. These are psychrophile and were collected a little in the littoral zone from October on.
