Lake Biwa, the largest lake in Japan, has experienced eutrophication from late 1960s to mid 1980s. I will present the result of analyses conducted on long-term data series to illustrate the different responses of crustacean zooplankton to eutrophication. The population response of key species was investigated at different temporal scales. The results contribute to the debate about the use of zooplankton as indicator of environmental changes in Lake.
