Abstract
Lake Jusan is a brackish lake located in the down reaches of Iwaki River system and is one of the most famous fishing places of Corbicula japonica in Japan. A growth model of C. japonica was developed by applying DEB (Dynamic Energy Budget) modeling based on Kooijman (2007). The growth model was combined with the lake water quality model developed and validated by our previous studies in Lake Jusan to estimate phytoplankton biomass as food of the bivalve. Although temporal distribution of reproduction was not in a good agreement with the measured results of larvae, the total populations change of C. japonica during a year was in a reasonable range compared with the measured data.
