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.
