抄録
The occurrence characteristics of zooplankton in brackish Lake Obuchi, located in the center of the Shimokita Peninsula in Aomori Prefecture, were observed from April 2001 to March 2004. Mean densities of the zooplankton at the freshwater river estuary and the center of the lake reached 5.4 × 104 and 3.4 × 104 individuals m-3, respectively, and each density showed two peaks in spring and autumn. The number of taxa found in this survey was 45. The dominant taxa were Copepoda (Acartia hudsonica, Harpacticoida and Poecilostomatoida), and larvae (Polychaeta, Gastropoda, Pelecypoda, Pelecypoda and Balanomorpha). In winter, Rotatoria showed a higher density than other taxa. There was no significant difference in either the density or taxa composition of zooplankton between the stations.
