Keywords:ecosystem model, diatom, Eucampia, red tide, Harima-Nada

A coastal region is closely linked human society, and it is very influenced by anthropogenic effects.
Especially, oligotrophic waters became a problem last few decade in Harima-Nada.
The oligotrophic waters in Harima-Nada is considered that related to changes of species composition of phytoplankton.
Here, the bloom of Eucampia zodiacus and distribution of DIN in Harima-Nada were calucurated by used of the numerical simulation model.
