In addition, Climate change causes sea level rise, thereby increasing the existing water level along with that in large rivers and also causing storm surge, which coincides with the time of flood discharge at Dau Tieng and Tri An reservoirs.

Eutrophication in waters often results in cyanobacterial mass development. Cyanobacterial blooms can cause major disruptions of the aquatic ecosystem due to strong negative effects on herbivorous zooplankton such as Daphnia. In this study, we used extract of cyanobacterial material from a scum to chronically expose to a tropical micro-crustacean, Daphnia lumholtzi.

Blooms of blue-green algae (cyanobacteria) occur in freshwater as well as marine environments and cause negative impacts to other organisms via production of natural toxins. Microcystins (MCs), producing by many species of cyanobacteria, cause liver damage, cancer, mental disorder and seriously effects on human health.

Microcystis is a bloom-forming, common cyanobacterium in Dau Tieng reservoir used for public water supply. To assess the presence of potentially microcystin-producing Microcystis, molecular techniques were conducted and acute toxicity bioassays were performed with the microcrustacean Daphnia magna exposed to cyanobacterial crude extracts. Potentially toxigenic of isolated strains was characterized by amplifying mcyD genes and identification of Microcystis was confirmed by 16S rRNA amplification.

In this study, a 16S rDNA clone library was used to evaluate the diversity of potential microcystin producing cyanobacteria and polymerase chain reaction (PCR) was used to analyze the diversity of this population based on the presence of the mcyD gene in samples collected during a bloom season. The results revealed that Microcystis genera from the Dau Tieng reservoir (DTR) contained several genotypes. The isolated Microcystis strains from the DTR were found to consist both toxic and non-toxic species within species and population.
