Summary

The authors used SEM to clarify the detailed morphology of Cymbella janischii that appeared in the Tama River.Through this study,we confirmed mat-like colonies even in early summer. We also attempted to understand the appearance of large diatoms not only by counting the number of cell, but also by measuring the capacity of the cells, and obtained good results.Silt has continued to flow down from the upstream dam,and the previous vegetation has not recovered for a long time.It was extremely regrettable that we were not able to conduct experiments to remove C.janischii or to consider countermeasures.
