Abstract
- This study aimed to understand a distribution of dominant species and potential risky species on phytoplankton and their relationship with physico-chemical factors at major ports in Korea in 2007. During the study periods, Chaetoceros socialis (11.1%), Ch. pseudocrinitus (10.6%) and Skeletonema costatum (10.3%) appeared to be dominant species at Pusan port. S. costatum (10.8%) and Detonula pumila (10.4%) were dominant species at Ulsan port, Paralia sulcata (20.5%) and S. costatum (30.7%) were at Incheon port, Odontella longicruis (11.3%), and S. costatum (41.8%) were at Gwangyang port. Potential risky species (red tide and toxic species) appeared 17 species in diatoms, 7 species in dinoflagellates and 1 species in Euglenoide. Multi regression of results, Ch. socialis and Ch. pseudocrinitus were affected by salinity (p<0.01) at Pusan port. At Ulsan port, dominant species (S. costatum and D. pumila) were highly affected by total suspended solids (TSS) than salinity. At Incheon port, dominant species were highly affected by chemical factors (ammonia, nitrite and phosphate) than physical factors such as 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, nitrate and phosphate at Ulsan port. As a results, indicated that dominant species were highly related to physical factors than chemical factors, while risky species were related to chemical factors such as nutrients.
