Purification function by river and lacustrine benthos

Study period:1990 - 1992
Research overview:
1) To check the secondary production amount of benthos of Kasumigaura, Yunoko Lake, experimental lakes of organic ecosystems, etc., and to evaluate the water purification functionof benthos from the relation with nutritive salt concentration. 2) To fix underwater plants of floating leaf plants in atank with lacustrine mud, and to check experimentally the difference in the affects aquatic plants have on the water depending on the difference in kind and concentration.
