“…The great difference in brackish-water copepods between the two sides of the Tsushima Strait indicate that the strait has played the role of an effective barrier for their dispersion. Occasional transportation from Korea to Japan by the Tsushima Warm Current, which was recently observed for a bloom of a dinoflagellate (Onitsuka et al 2010), is probably impossible for brackish-water copepods.…”

“…If flushed-out brackishwater masses are transported by ocean currents and copepods survive within the masses, they could disperse to distant islands across the sea as sometimes happens through dispersion via ship ballast water. Although it has not yet been reported definitely for brackish-water copepods, satellite observations have revealed that a bloom of harmful dinoflagellates on the southeast Korean coast was transported to Ͼ500 km away to San-in district, western Honshu Island, over about two weeks to one month by the Tsushima Warm Current (Onitsuka et al 2010).…”

Brackish-water calanoid copepods, defined as those predominantly inhabiting oligo-and mesohaline waters, were investigated at 45 rivers in western Japan during 2006-2009 to review their faunas and, for comparison, 4 rivers of Korea in 2006. Eight species (Acartia ohtsukai, A. sinjiensis, A. tsuensis, Pseudodiaptomus inopinus, P. ishigakiensis, Sinocalanus sinensis, S. tenellus and Tortanus derjugini) were identified as brackish-water calanoid copepods from Japan. Among them, P. inopinus was most often collected; it occurred in 38 rivers. Acartia tsuensis and A. sinjiensis were also frequent species in Japan. Pseudodiaptomus ishigakiensis discovered from Kyushu Island is new to the mainland of Japan. From the rivers of Korea six species were identified (A. ohtsukai, A. sp., P. inopinus, P. sp., S. tenellus and T. dextrilobatus). Based on the present and previous studies, a total of 13 brackish-water calanoid copepods have been recorded from Japan and Korea, of which eight species, including three continental relicts (A. ohtsukai, S. sinensis and T. derjugini) in Kyushu Island, are common to both regions. Among them, only two species (P. inopinus and S. tenellus) are distributed widely on both Japanese and Korean coasts of the Tsushima (Korea) Strait. This indicates that the faunas of brackish-water calanoid copepods are very different between Japan and Korea despite the short geographical distance (about 170 km) and that the Tsushima Strait has played the role of an effective barrier for their dispersion.

“…The initiation and development of C. polykrikoides blooms have been shown to be related to diurnal migration behavior (Park et al, 2001;Y.-S. Kim et al, 2010), mixotrophy (Jeong et al, 2004), light quantity and quality (Oh et al, 2006), the production of toxins lethal to grazers (Jiang et al, 2009;Tang and Gobler, 2009a,b), allelopathic effects on competing phytoplankton , transport by large-scale currents (Onitsuka et al, 2010), and stimulation by nutrients such as nitrogen and vitamins . None of these factors, however, can account for the rapid and large geographic expansion of the species across Asia, North America, and even Europe during the past two decades.…”

Abstract. Red tide is a common phenomenon and almost present every year in Lampung Bay. In 2012, the red tide in Lampung Bay showed a different characteristic compared to the previous ones. The research was conducted to analyze the characteristics of organisms causing the red tide and the factors affecting its occurrence. Assessments were done by identifying the dominant phytoplankton and observing the environmental condition using rapid assessment method. Seawater sampling was conducted in 15 stations in December 2012 to monitor the phytoplankton abundance, nutrient, and physical condition. The results showed that the organism dominating the phytoplankton population is Cochlodinium sp., comprising of 85.89% of the total phytoplankton suggesting it was the red tide organism in the Bay. The average abundance of this species in the stations was 2.0 x 10 4 cells/L. Choclodinium sp. was present agglomerated and distributed along the west coast of the bay. The highest concentration of the organism was found around the tip of the bay. The outbreaks of Choclodinium sp. were induced by the high concentration of nitrogen in the coastal water with N:P ratio of 35.5. Moreover, the physical condition of the coastal water strongly influenced the distribution and abundance of Cochlodinium sp. in the bay.
