dc.description.abstract | This study aimed to understand relationship between dominant and risky phytoplankton species and environmental factors at major ports of Korea in 2007. During the study periods, Chaetoceros diadema (7.7 %), Ch. debilis (6.9 %), Ch. difficilis (5.1 %), Ch. pseudocrinitus (18.9 %), Ch. spp. (5.5 %) and Skeletonema costatum (10.1 %) appeared to be dominant species at Pusan port. Ch. diadema (43.8 %), Ch. pseudocrinitus (9.8 %) and S. costatum (21.2 %) were dominant species at Ulsan port, Ch. pseudocurvisetus (12.3 %), Paralia sulcata (18.1 %) and S. costatum (53.1 %) were at Incheon port, Eucampia zodiacus (17.1 %), and S. costatum (57.9 %) were at Gwangyang port. Risky species (red tide and toxic species) appeared 17 species in diatoms, 7 species in dinoflagellates and 1 species in Euglenoides. Pseudonitzschia seriata and P. pungens, which appeared at Gwangyang port during 4 seasons, are able to produce domoic acid. Alexandrium and Dinophysis were found in August throughout the study area, which can cause paralytic shellfish (PSP) and diarrhetic shellfish (DSP). Distribution pattern of Chaetoceros diadema, Ch. debilis, Ch. difficilis, Ch. pseudocrinitus and Ch. spp. was affected by salinity (p<0.01) at Pusan port. At Ulsan port, dominant species was highly affected by total suspended solids (TSS) than salinity. At Incheon port, dominant species was highly affected by chemical factors (ammonia, nitrite and phosphate) than physical factors (water temperature and salinity). Pseudo-nitzschia spp. was affected by nutrients such as nitrite and silicate in all study areas. Alexandrium and Dinophysis were affected by COD at Ulsan port. The abovementioned results indicated that dominant species were highly related to physical factors than chemical factors, while risky species were related to chemical factors. | - |
