Abstract
The patterns of diel horizontal migration (DHM) of 7 copepod species are compared as part of a general investigation of the zooplankton adaptations to the surf zone habitats. In a sandy shore surf zone of Yongil Bay, 3 sites such as the bottom and surface of 1 m water depth and water's edge are sampled with a sledge net(n=108). The surf zone copepod assemblage is dominated by 7 species; Acartia hudsonica, Fseudodiaptomus marinus, Paracalanus indicus, Calanus sinicus, Oithona similis, Sinocalanus tenellus and Labidocera bipinnata. Threefold variations in copepod abundance are observed within a diel cycle. Abundances of 7 dominant species and total copepods captured in the surface exhibit significant diel differences, but those taken in the bottom are not significantly affected by diel period. It is shown that about
동물플랑크톤이 쇄파대에서 어떻게 적응하여 살아가고 있는가를 연구하면서, 부유성 요각류 일곱 종의 주야 수평이동 양상을 조사하여 비교했다. 동해 영일만 쇄파대에서 수심 1m 되는 곳의 표층과 저층과 해변가 세 곳을 썰매형 네트로 채집했다(총시료수=108개). 쇄파대 요각류 집단은 일곱 종 (Acartia hudsonica, Fseudodiaptomus marinu, Paracalanus indicus, Calanus sinicus, Oithena similis, Sinocalanus tenellus, Labidocera bipinnata)이 우점했다. 쇄파대 요각류의 주
