Japanese National Representative of International Association of Theoretical and Applied Limnology since 1977. 1980-1983, President of Japanese Society of Limnology. In 1977, Prize of the Oceanographic Society of Japan for "Biogeochemical Studies in the Sea".

Major Scientific Activities were directed to the following fields:

Primary production and the carbon and nitrogen cycle in the sea and in lakes. Biogeochemical studies of sediments and sedimentation in lakes. Member of SCOR Working Group 15, Photosynthetic Radiant Energy. Studies of meromictic lakes and the volcanic acid lakes.

Studies of eutrophication of inland bays and the nitrogen metabolism in lakes. Studies of phytoplankton production and oxygen deficiency in tidal rivers.

Professor Yatsuka Saijo coordinated for many years the collaborative work Brazil/Japan in limnology. The experience of this collaboration was an important step in the development of Tropical Limnology and stimulated a great deal of studies that followed the expeditions to the Rio Doce Valley Lakes, Eastern Brazil, Minas Gerais State.

Professor Saijo was a scientist with a great wisdom and knowledge. He was also an artist, a painter and a person with a very high standard of moral and ethics, an example for future generations. He had a very fruitful and productive life with many important contributions to Limnology and Oceanography. He also prepared several very highly qualified limnologists which are following his scientific work.

His death was a great loss to science and limnology. He his survived by his wife Mrs. Noriko Saijo, son, and daughter.

This number of Brazilian Journal of Biology is dedicated to the memory of Prof. Yatsuka Saijo.
