Abstract: This study has been attempted to understand characteristics of algal blooms in relation to the marine environment of Jinhae Bay, located in the southern coastal waters of Korea, using 25 years worth of data since the first known occurrence of algal blooms in 1981. Skeletonema costatum, Heterosigma akashiwo and Prorocentrum sp. turned out to commonly appear as dominant causative organisms of the blooms in all the regions but their appearance conditions were different from place to place. That is, Skeletonema costatum appeared with a wide range of variations of water temperature and salinity, i. e. eurythermal ᆞ euryhaline in Masan and Jinhae Bays but it appeared with a narrow range of variations of water temperature and salinity i. e. stenothermal ᆞ stenohaline in other regions. Heterosigma akashiwo appeared under a wide range of variations of water temperature and salinity, i. e. eurythermal ᆞ euryhaline in Masan and Haengam Bays but it appeared with a narrow range of variations of water temperature and salinity, i. e. stenothermal ᆞ stenohaline in Woumun Bay. Prorocentrum sp. appeared with a narrow range of variation of water temperature and a wide range of variation of salinity, i. e. stenotermal ᆞ euryhaline in Masan and Dangdong Bays but it appeared with a narrow range of variations of water temperature and salinity, i. e. stenothermal ᆞ stenohaline in Haengam Bay.
