각기 다른 해양 환경 특성을 보이는 서해, 남해, 동해, 제주 연안역을 대상으로 춘계 (5월)와 하계 (8월)에 출현한 부유성 요각류의 군집구조에 대하여 분석하였다. 봄과 여름에 출현한 부유성 요각류는 총 73종이었으며, 이 중 연안종이 28종이었다. 봄 (49종)에 비해 여름 (58종)에 출현 종이 다양하였다. 요각류 출현 개체수는 봄과 여름 Chl-a 농도가 낮게 나타난 동해연안해역에서 가장 낮았으며, 봄에 Chl-a 농도가 높게 나타난 서해연안해역에서 출현 개체수가 높게 나타났다. 그러나 여름에 제주연안해역에서 Chl-a 농도가 0.6 μg L-1으로 낮게 나타났으나, 높은 출현 개체수를 보였다. 봄에 한국 연안에서 우점적으로 출현하는 요각류는 Acartia hongi, A. ohtsukai, Paracalanus parvus s. l., Oithona similis이었다. 여름에는 이들 종 이외에 A. omorii, A. pacifica, A. steueri, Calanus sinicus, Corycaeus affinis, Corycaeus sp., Pseudodaiptomus marinus, Tortanus forcipatus이었다. Paracalanus parvus s. l.은 봄에 조사 해역에서 최우점종 또는 차우점종으로 생태적 지위를 달리하였으나, 여름에는 전 조사해역에서 최우점종으로 출현하였다. 요각류 군집특성은 수온, 염분, Chl-a 농도 등의 환경 요인에 따라 서해, 남해, 동해, 제주 4구역으로 명확하게 구분되었다.

The Korean coast is divided into the West Korea Coastal zone (WKC), the South
Coastal zone of Korea (SCK), the East Korea Coastal zone (EKC), and Jeju Coastal zone of Korea
(JCK). Each coastal zone has different marine environment characteristics. This study analyzed
zooplankton data of KOEM (Korea Environment Management Corporation) collected in the
Korean coastal waters the spring and summer of 2015 and 2016. In spring, water temperature
was lowest in the JCK, and gradually increased in the order of EKC, SCK, and WKC, while in
summer lowest in WKC and increased in the order of EKC, SCK, and JCK. Salinity was lowest in
WKC which had many rivers flowing inland, and increased in the order of SCK, EKC and JCK in
spring. In summer it was lowest in JCK and increased toward WKC, SCK, and EKC. In summer,
Chlorophyll-a concentrations were generally low, but was lowest in JCK in spring. In the study
area, a total of 77 species occurred, of which 50 species did in spring and 65 species in summer.
The number of species was lowest in JCK and highest in SCK in spring and summer, respectively.
Paracalanus parvus s. l. was the most dominant species or the second dominant species in Korean
coastal areas in spring, but it was predominant in summer. In addition, in spring Acartia hongi,
Calanus sinicus, Oithona similis were predominant in WKC, Oithona similis and Corycaeus
affinis in SCK, O. similis and Corycaeus sp. in EKC, C. affinis and O. setigera in JCK. In summer
Corycaeus spp., O. similis, A. hongi, Tortanus forcipatus were predominant in WKC, C. affinis,
Pseudodiaptomus marinus in SCK, O. similis, A. omorii, Corycaeus sp. in EKC, and A. steueri,
A. pacifica, Oithona sp., C. sinicus in JCK. The copepod community in the Korean coastal areas
were classified into four areas, WKC-western SCK, eastern SCK, EKC and JCK according to
differences in environmental factors such as water temperature, salinity, Chl-a concentration, and
suspended matter concentration of each coastal area.
