- Abstract
- In this study, we analyzed the stomach contents of 303 john dory Zeus faber specimens collected from the South Sea of Korea in 2024. The specimens ranged in total length from 16.0 to 44.2 cm. The stomach contents of 151 specimens containing prey items indicated that fishes (Pisces) were the dominant prey group, representing 99.6% of the index of relative importance (%IRI). Engraulis japonicus was identified as the primary prey species. Other prey items, including Caridea, Cephalopoda, and Isopoda, were present but contributed less than 0.4% each to the %IRI. The trophic level of John Dory in the South Sea was 4.5. Analysis of dietary changes with growth indicated that fish remained the dominant prey across all size classes, with over 98.0 %IRI. The mean weight of prey per stomach increased significantly with body size (P<0.05).
