Diatoms in the Kase River (Kasegawa) Estuary

Abstract

The diatoms of brackish water in the Kase River (Kasegawa) Estuary, Saga Prefecture, Japan were investigated. A total of 238 taxa, distributed among 50 genera, were recorded in an epilithic diatom sample. In the diatom assemblage, Hydrosera triquetra was a predominant taxon and the best represented genera were Bacillaria, Gyrosigma, Nitzschia and Synedra. In nineteen plates, all taxa are depicted by microphotographs.
