| Abstract | This study aimed to determine relationship between Kai algae and water quality using the Applied Algal Research Laboratory-Physical and Chemical Score (AARL-PC score) and inverse distance weighting (IDW) in the Mekong River. Kai algal habitats were discovered at three sampling sites during a survey of the Mekong River, Chiang Khong district, Chiang Rai Province, Thailand in January and February 2022. Kai algae were collected in the field and identified by microscope. Kai morphology and environmental factors including length, dry weight, water conductivity, DO, BOD, nitrate nitrogen, soluble reactive phosphorus and ammonium nitrogen were investigated. The results showed two Kai genera, Cladophora sp. and Rhizoclonium sp., were presented in the sampling sites. In January, BOD had a strong positive relationship with the length of Kai algae while ammonium nitrogen had a significant relationship with water conductivity (p < 0.01), and DO had a significant relationship with dry weight (p < 0.05). In February, BOD had a strong positive relationship with the length of Kai algae (r = 0.9804), while ammonium nitrogen had a significant relationship with water conductivity (p < 0.05). IDW derived from the AARL-PC-score revealed that clean-moderate water quality was directly related to environmental factors in January and February and can be used to determine Kai algal growth in the Mekong River. |
