| Outline of Final Research Achievements |
We surveyed aquaculture ponds at different altitudes in order to evaluate the effect of global warming for proliferation of toxic cyanobacteria. Water temperature, nutrients, chlorophyll-a (phytoplankton surrogate), cyano-toxin microcystin were measured. Phycocyanin-ITS gene (total cyanobacteria surrogate), microcystin synthesis gene mcyB (toxic cyanobacteria with producing microcystin surrogate) were quantified by real-time PCR. We analyzed the obtained data by statistical model. The results clearly showed the following facts. The increment of water temperature and the increase of both N and P loading enhanced the growth of phytoplankton. Increment of water temperature and increase of nutrients N loading enhanced the growth of the total cyanobacteria and the toxic cyanobacteria. However, we found new fact that the standing crops of cyano-toxin microcystin was suppressed by the increment of water temperature, though the increase of nutrients N loading added to microcystin.
