Abstract: ABSTRACT:The study of ichthyoplankton community associated with
oceanic features on the continental shelf of southern East
China Sea (ECS) was conducted in early winter from 2006
to 2009. The species composition of the ichthyoplankton and
its spatial distribution was classified and compared with oceanic
front. A total number of 1,809 fish larvae individuals
were sampled from 5 field surveys, and represented 76 families
and 137 species. Using the Bray-Curtis dissimilarity, the
abundance of species found to exceed 0.5% of the total sample
from 36 stations were classified into four groups: China
Coastal Group, Mixed Shelf Group, Taiwan Strait Group, and
Kuroshio Group. The shallow water species Sebastiscus
marmoratus dominated the China Coastal Group, while the
Mixed Shelf Group was dominated by Saurida spp., Trichiurus
lepturus, and Bregmaceros spp. The Taiwan Strait Group
was dominated by Engraulis japonicus and Benthosema
pterotum. The dominant species in the Kuroshio Group was
found to include Sigmops gracile and unidentified Myctophid
larvae. The spatial distribution of the ichthyoplankton
community groups was superimposed on a thermal front
map of the study area. This clearly revealed that the China
Coastal Front could be the boundary which separated the
China Coastal Group on the west and the Mixed Shelf Group
on the east. In addition, ichthyoplankton were found to in-crease in abundance and diversity in the region close to the
Kuroshio Front.
