| Research Abstract |
1) Samples of Lakes Shinji and Nakaumi from 1960's stored in the laboratory were arranged and put in the specimen boxes. 2) I taxonomically examined these samples, and changed species names and occurrences for several species. Cell number of Prorocentrum minimum causing red tides in Lake Nakaumi gradually decreased after 2005. A minute diatom, Chaetoceros minimus was firstly identified by SEM observation. 3) M. contortum and other several species showed seasonal changes of occurrence. 4) Four culture strains were isolated for a research of mold smells in Lake Shinji. 5) I prepared to show photos and descriptions about 180 species of phytoplankton of Lakes Shinji and Nakaumi in a homepage.
