초록

We aimed to study the structure of the zooplankton community in the Southern Sea of the Republic of Korea. Zooplanktonsamples were collected in February (winter), May (spring), August (summer), and November (autumn) of2020. The zooplankton collected belonged to a total of 166 taxa and 12 phyla, including some unidentified individualsand those from upper taxa. The number of taxa collected were the highest in winter at 117, and the lowest in May at93. The dominant taxa were Oikopleura spp. in the winter, Gastropoda larvae in the spring, and Paracalanus parvuss.l. in the summer and autumn. The community structure of the zooplankton was clearly distinguishable between theseasons. The mean density of zooplankton was the highest in autumn and the lowest in summer (576,039 and 313,000individuals/1,000 m3, respectively). Based on the analysis of relationships between the density of the six major taxaand environmental factors, a significant correlation (P<0.05) between the four taxa and environmental factors wasfound. Therefore, in order to understand changes in the zooplankton community, quantitative and qualitative investigationsof biological factors as well as physical factors should be conducted.
