Abstract

This paper deals with the work performed at the Department of Zoology of the Faculty of Sciences in Saigon on planktonic material, collected in the Bay of Nhatrang, Central Vietnam. After preliminary considerations on the physical factors relating to plankton life in the Bay, the materials and methods are described. Follows a list of the planktonic organisms studied and identified, and the descriptions of 154 species of diatoms, containing mostly planktonic species mixed with a few benthic species. This is the first of a series of papers dealing with plankton organisms recorded in the Bay of Nhatrang. As it is intended to be a tool for Marine Biology students as well as interested, beginners, the systematic and descriptive characteristics have been reduced to a minimum. Stress was on making detailed and clear illustrations of the organisms described.
