Harmful algal blooms are common world-wide and pose a serious problem to the aquaculture and fisheries industries. Flagellates such as Cochlodinium polykrikoides, Heterosigma akashiwo, Karenia mikimotoi and Chattonella aniiqua are recognised potentially harmful bloom organisms implicated in fish mortalities in Korean coastal waters. Although a bloom of Chattonella antiqua was reported for the first time from Jindong bay in 1983, the chloromonads species, however were never found in such high cell concentrations and formed large blooms in Korean coastal waters since 1983. In addition, the history of Chattonella spp. in the Korean coastal waters is not long. Because the cells are so fragile and difficult to preserve, they might be overlooked if cell density is low.
We has been conducted an extensive marine phytoplankton monitoring program for several years, and Chattonella spp, were routinely found during regular monitoring in the Yeosu coast of southern Korea. We describes that the composition and distribution of Chattonella with environmental characteristics were based on bottle samples collected weekly from May 2004 to October 2005 at four stations. All 4 species were identified (C. antiqua, C. marina, C. globosa and C. ovata). In addition, C. globosa and C. ovata were firstly recorded in Korean coastal waters. Those are mainly presented during the spring-summer seasons when water temperature and salinity ranged 17.8~28.4℃ and 28.1~33.9 psu respectively. C. globosa was initially appeared and following C. antiqua, C. marina and C. ovata. The most abundant cell concentrations were regularly measured at the middle layers.
No bloom events of Chattonella occurred during the period of our observation, but it seems that environmental conditions may be followed by the great possibility of the blooms of Chattonella in Korean coastal waters. Therefore, continued monitoring for this species is needed to learn more about its life cycle, ecological role and potential for fish kills.
