| 内容記述 | Phytoplankton dynamics in a shallow hypereutrophic lake, Lake Teganuma, about 40km NE of Tokyo, were studied over 4 years from June 1972 to November 1975. Properties of phytoplankton dynamics in such environment differed in several respects from deep eutrophic lakes. Water bloom appeard twice a year, summer and winter. Dominant species were blue-green algae such as Microcystis, Oscillatoria, Anabaena during the summer, and Chlamydomonas, Euglena in Winter. Chlorophyll a content was in a range of 140-680mg/m^2. Light saturated photosynthetic rates were almost above 10mg O_2/mg chl. a/hr (with maximum value of 24.5mg O_2/mg chl. a/hr) throughout the year. Average rate of daily gross photosynthetic production of 34.8g O_2 (13.1g C)/m^2/day recorded in the present study. This value was an upper limit of values reported in natural waters, and it was quite cloes to a value of 36.4g O_2/m^2/day which has been observed in outdoor mass cultures of Chorella. Mean annual gross production over 3 years was estimated as 4,190g O_2 (1,571g C)/m^2/year and this value was to be the highest so far encounterd in natural waters. Photosynthetic efficiency of radiation energy by phytoplankton was 3.28% for PHAR and this value may also be the highest in natural waters. | |||||
