Abstract

Distribution characteristics of two dominant paracalanids of the family Paracalanidae on temperature and salinity were studied in the brackish and coastal waters from the West and South coasts of Korea. Bestiolina coreana mainly occurs in a range of 29.8~31.3 psu salinity and temperature of more than about $20^{\circ}C$, while Paracalanus parvus s. l. mainly occurs in a range $17{\sim}20^{\circ}C$ temperature and more than 30 psu salinity. The fact clearly indicates that temperature and salinity was a major factors in spatio-temporal distribution between these two paracalanids.

서해안과 남해안의 기수역과 연안해역에서 우점하는 곁노벌레과(Paracalanidae) 2종 간의 수온과 염분에 따른 출현 양상을 파악하고자 영광 인근해역을 중심으로 2007년 가을철, 2008년 겨울철, 봄철, 그리고 여름철에 걸쳐 사계절조사를 실시하였다. Bestiolina coreana는 봄철과 겨울철에 출현하지 않았으며, Paracalanus parvus s. l.는 연중 출현하는 것으로 나타났다. 이들 종간의 수온과 염분에 따른 출현 양상에서는 수온 $20^{\circ}C$ 이상과 32 psu 미만으로 낮아지는 시기에는 P. parvus s. l.보다 B. coreana의 개체군이 월등하게 높게 유지되는 것으로 나타나 결과적으로 계절에 따른 수온과 염분 변동이 두 종의 출현 양상에 영향을 미칠 수 있는 중요한 단서로 제공될수 있음을 의미한다.
