In 2017, total coliform (TC), fecal coliform (FC) and fecal Streptococci (FS) bacteria were examined in seawater
samples collected at coastal sites on Jeju Island (Aewol as a control, Namwon, and Daejeong) and at Pohang (Yeongil
as a control, Guryongpo-North, and Guryongpo-South) to examine the correlations between the density of fish farms
and distributions of the indicator bacteria. Only a few TC, FC, and FS colonies were detected in all of the samples
obtained from Jeju Island. Of note, 2,000 and 1,000 CFU of FS 100 mL-1 were detected in samples from Guryongpo-
South in June and August, respectively. Although the total area of approved fish farms located within 5 km of the
sampling point at Guryongpo-South is 5-16 times smaller than in other regions, the number of indicator bacteria was
highest in this region. Therefore, microbiological pollution in the Guryongpo-South region might be due to sources
other than the effluent released from nearby fish farms.
