摘要: Abstract This study was conducted to examine and determine the factors affecting dominance of blue‐green algal species genus Microcystis, Anabaena, Oscillatoria Phormidium from 1988 1990 in eutrophic Lake Kasumigaura. The dominancy three Anabaena species, A. affinis,A. flos‐aquae spiroides, took place early summer, while Microcystis M. aeruginosa, viridis wesenbergii, summer fall. Water samples were collected at Tsuchiura Harbour correlations between cell numbers water qualities investigated. growth rates algae situ determined. Af. aeruginosa showed highest increasing rate, lowest decay rate species. exhibited high single temperature, pH, total chemical oxygen demand (T‐COD) dissolved (D‐COD). ...
