| This study was conducted to identify the influences of light-to-nutrients ratio on the zooplankton and phytoplankton community. Various experiment conditions such as HL (high-light and without zooplankton), HLZ (high-light and with zooplankton), LL (low-light and without zooplankton), and LLZ (low-light and with zooplankton) were adjusted. Changes in biomass of phytoplankton species with the incubation time showed a similar tendency in the continuous cultures, but the change of species composition in the continuous cultures was detected. Cyanophyeeae (Phormidium sp.) seems to be affected by the existence of zooplankton. Also, the predominant species were Chlorophyceae (Staurastrum spp., S. dorsidentiferum, Coelastrum cambricam, Chlorella sp., Krichnerialla sp.) in a high-light environment and Bacillariophyceae (Melosyra granulata, Synedra acus, Fragilaria crotonensis) in a high-light environment. The estimated mean POC concentration (after twenty days) in a high-light environment was two times higher than that for a low-light environment. P : C ratio of seston component in a low-light environment was higher than that for a high-light environment. Changes in biomass of zooplankton species during the incubation time were higher than that for a high-light environment. |
