초록

We investigated mesozooplankton community in the Yellow Sea in summer immediately after the typhoon passed. Total mesozooplankton density ranged from 1,323 to 6,397 ind. m-3 and the biomass ranged from 3 to 28 mg C m-3 by stations. The dominant species of the research area were Paracalanus parvus s.l., Oithona atlantica, Acartia omorii, Oikopleuridae, Sagittoidae juvenile and Calanus sinicus in that order. Mesozooplankton community was divided into two groups by cluster analysis : the stations located in coastal and open seas as one group, and the stations located in the middle into another group. The number of species, density and richness of mesozooplankton were significantly lower in the middle region. Mesozooplankton density and biomass were not significantly correlated with chl-a concentrations, unlike previous studies in spring and autumn. This community characteristic in summer may be due to the passing of the typhoon, or other environmental influences.
