Abstract
We investigated the effect of the water quality on the phytoplankton community in the 2 sites of Andong reservoir. The water temperature in 1 m and 4 m depth (LH) was changed, but the temperature in 7 m depth (HD) was constant irrespective of the season. The dissolved oxygen in LH was lower than that of the HD. The turbidity of water and pH were similar in both depths. The concentration of chlorophyll-a decreased with increased depth of water. Fifty nine phytoplankton taxa were identified and the most abundant phytoplankton group was Chlorophyceae with 25 taxa (43%). Cyanophyceae and Bacillariophyceae consisted of 17 taxa (29%) and 10 taxa (17%), respectively. Cryptophyceae had 3 taxa (5%) and Synurophyceae and Dinophyceae had 2 taxa (3%) in Andong reservoir. Dominant species were Elakatothrix gelatinosa (Aug, 23) and Eutetramorus fottii (Aug. 23 and Sep. 28) from Chlorophyceae, Aphanizomenon cf. flos-aquae (Aug. 16), Microcystis aeruginosa (all sampling periods), and Aphanocapsa delicatissima (Oct. 27) from Cyanophyceae, and Cyclotella stelligera (Oct. 13), Cyclotella sp. (Oct. 13 and Oct. 27) and Synedra acus (Aug. 16) from Bacillariophyceae.
