초록
사계절 수층별 채집에서 요각류는 총 40속 96개 분류군이 동정되었다. 가을철에 가장 많은 종류가 대마난류를 통해 동해로 유입되고 있었다. 정점별로는 모든 계절에서 유의적인 차이를 보이지 않았다 (ANOVA, p>0.05) 각 계절의 수심별 비교에서는 여름철과 겨울철에 중 저층에서 다소 많은 분류군이 동정되었다. 요각류의 총 개체수는 종수와는 달리 봄철에 가장 많은 163.8 개체/
In the Korea Strait total of 96 copepod taxa (40 genera) were identified from the seasonal and vertically stratified samples. Species richness was the highest in fall and the abundance was the highest in spring. Spatial differences were not significant within each season, but was meaningful among seasons. The water column layers of high abundances were near bottom in spring, and surface in summer and fall. Species association of copepods was examined by the cluster analysis. There are the two different results on the timing of the intrusion of East Sea Cold Water to the Korea Strait in the deeper layer based on physical data [in winter (Lee et al., 1938) vs in summer (Cho and Kim (1998)]. This study based on the distributional characteristics of copepods supported Cho and Kim (1998)'s result. Although sea water temperatures was one of major controlling factors of the copepod distribution in this strait, biological interrelation among the species such as common or exclusive exploitation of the habitat was also responsible for the observed distributional patterns.
