This study took plankton sample at ten fixed stations in the northern South China Sea in two cruises (July 2003, February 2004). Oblique plankton samples from 100m to surface were collected by using plankton net of 180-cm in length with 45-cm diameter and 200μm mash. Totally, 149 copepod species (92 calanoids, 16 cyclopoids, 36 poecilostomatoid, and 5 harpacticoids) were identified. They belong to 26 families and 52 genera.
The ten most abundant species of copepods were: Oncaea venusta, Acrocalanus gibber, Paracalanus parvus, Temora turbinate, Paracalanus aculeatus, Oncaea mediterranea, Oithona plumifera, Oncaea media, Farranula gibbula, and Clausocalanus furcatus. The range of copepod abundance was from 295 to 3,686 ind. m-3. The high copepod diversity, from 3.09 to 5.23 nits, indicated high diversity of species and an relatively even distribution. Furthermore, the copepod assemblage was analyzed by using MDS, Cluster, and ANOSIM analyses. We found that the variation in distribution of plankton copepods in the northern South China Sea was spatially insignificant, but temporally significant. The feeding impact of copepods on phytoplankton was 0.63-11.49 % per day in summer and between0.33-18.85 % per day in winter.
