The community of plankton and the environmental factors were investigated in Lake Soyang from January to July 1994. The relationship between transparency and biovolume of phytoplankton was negatively correlated. Phytoplankton dominants in Lake Soyang were Anabaena spp., Microcystis aeruginosa, Asterionella formosa, Asterionella gracillima Melosira distans, Synedra acus, and Asterococcus limneticus. Zooplankton dominants were Polyarthra spp., Keratella spp., Asplanchna placentula, Bosmina coregoni, and Daphnia longispina. Phytoplankton and zooplankton were clearly related each other with respect to biovolume, not to numbers. Microcystis aeruginosa rapidly increased and Daphnia longirostris disappeared in July, because Microcystis aeruginosa secret toxic substances to Daphnia longirostris. Transparency decreased from January to June, but increased in July. The highest number of phytoplankton was observed in April, and one month later, the zooplankton reached a maximal level in population density, implicating that spring bloom of phytoplankton was good feeding condition for zooplankton.
