Abstract Cyanobacteria blooming phenomenon was studied at the King's Royally Initiated Laem Phak Bia Environmental Research and Development Project, Phetchaburi, Thailand. During cyanobacteria blooming, the most abundant species that found in oxidation pond was Spirulina platensis (7.46_108 cells/m3), non-toxic producer and dominant species was Microcystis aeruginosa (1.73_108 cells/m3), the toxic producer. The toxins can be harmful to fish๊s liver in an oxidation pond. The relationship between cyanobacteria blooming and solar radiation (during November 2013 to February 2014) in the oxidation pond of the wastewater treatment system is the main research objective. The net radiometer and spectroradiometer were used to measure solar radiation. Daytime and seasonal variation of net radiation, UV, visible light and infrared including their proportions were used to analyze the relationship. Daytime net radiation in Cyanobacteria blooming was continuously increasing during a period were 354.8, 405.4, 417 and 448 w/m2, respectively that contrasts non-blooming period. Cyanobacteria blooming period and non-blooming period that has the proportion of UV (300 to 380 nm), visible light (381 to 750 nm) and infrared (751 to1140 nm) were stable. Monthly cumulative of net radiation on blooming period that increased from November to February were 26,245.4, 27,488.1, 27,850 and 30,042 w/m2, respectively. The results showed that the continuously increasing of net radiation over four months and the sharply increasing of UV radiation were the main reasons for the phenomenon.
