We examined monthly variations in community structure of larval fish assemblage in the coastal waters of south-central Korea in spring and summer, 2016. A total of 31 taxa of larvae were collected during the study period. Engraulis japonicus larvae were dominated in spring than summer. The larvae of Cynoglossus abbreviates, a spring spawners, were exclusively collected in spring, while those of Nibea albiflora, a summer spawners, were exclusively caught in summer. Due to those seasonal differences in abundance of the dominant species, larval fish community was divided into two main seasonal groups (i.e. April~May and June~August). In addition, summer group was divided into two significant subgroups (June~July and August). During August, the larvae of E. japonicus and N. albiflora sharply decreased in abundance due to abnormally high sea water temperature that was raised up to 28°C, with the temperature being out of range of their optimum spawning temperature.
