Distibution of ichthyoplankton in the south sea, Korea from summer

This study was carried out during the period of July 24~30, 1997 in order to obtain the information of the surface distributional features of ichthyoplankton in the adjacent waters of South Sea. The dominant fish eggs included the eggs of Engraulis japonicus, Maurolicus mullen and others. The eggs of Engraulis japonicus and Maurolicus mullen were 99.88% and 0.11% of the total eggs abundance, respectively. Nineteen taxa of pelagic larvae were collected. Among them 12 taxa were identified to the species level, and 7 taxa to the genus level. The domninant species was Engraulis japonicus accounting for 86.37% of the total larvae and followed by Gnathagnus elongatus (2.94%). Other major species were Argyrosomus argentatus (1.46%), Gobiidae spp. (1.23%), Paralichthys olivaceus (1.09%) and Auxis spp. (1.02%). These 6 taxa constituted 94.11% of the total larvae collected. The species diversities were low as E. japonicus eggs and larvae were predominant.
