The diet composition of john dory Zeus faber, was investigated using 266 specimens collected in the coastal waters of the South Sea, Korea. The specimens ranged in total length (TL) from 12.5 to 43.2 cm. The Z. faber fed mainly on Pisces and less often on Macrura. We further analyzed the data by dividing the specimens into five classes (<15.0 cm, 15.0-20.0 cm, 20.0-25.0 cm, 25.0-30.0 cm, ≥30.0 cm). The Z. faber diet shifted with size class from predominantly consuming Macrura to Pisces. The proportion of Macrura consumed decreased with increasing body size, whereas the consumption of Pisces increased gradually.
