| Since a substantial part of the total planktonic primary production is due to the activity of the picoplankton, seasonal change of chlorophyll a in the picoplankton, nanoplankton and microplankton was determined at four locations in Daechung Reservoir from September in 1998 to September in 1999. Chlorophyll a concentration (<$200;{mu}m$) was $0.7{sim}36.9;{mu}g/l$ In TAE (Taejeon site), $0.5{sim}23.5;{mu}g/l$ in MAN (Man site), $1.9{sim}20.1;{mu}g/l$ in HOE (Hoenam site), and $0.5{sim}17.4;{mu}g/l$ in DAM (Dam site). Generally it was observed the highest concentration of chlorophyll a was in September and the lowest in April to June. The relative contribution of chlorophyll a of each fraction was changed dramatically through the year. Relative contribution of chlorophyll a of microplankton was high from June to October, and low in March in all locations except HOE. However chlorophlyll a concentration of picoplankton fraction was $2.0{sim}24.3%$ of total chlorophyll a (<$200;{mu}m$) through the year and did not show any dramatic changes at all locations. |
