| Diurnal vertical distribution of phytoplankton and physico-chemical characteristics were studied in Kongsan reservoir during summer 1996, when a dense algal bloom, consisting mostly of Microcystis, developed. The maximum biomass was observed near the surface layer, where Microcystis aeruginosa dominated and declined gradually with depth. The dense population of blue-green alga M. aeruginosa acumulated near the surface layer during the early morning and evening, but abruptly decreased after sunrise. The most of biomass was distributed above 5 m of the water column and diurnal changes of biomass clearly appeared at the surface but was not showed upward and downward migration. The results of this study suggest that diurnal variation of biomass at the surface layer was affected by horizontal migration with wind. |
