Abstract
Diel and gastrointestinal changes in relation to the feeding intensity and prey composition of Apogon lineatus were investigated through the analysis of the diet contents of 174 fishes collected from the southeastern coast of Korea. Fish samples were collected at both day and night times during winter using a small bottom trawl. Stomach fullness, stomach contents index (SCI) and intestine contents index (ICI) of A. lineatus varied with day-night changes. Multivariate analyses revealed that dietary contents differed significantly between the stomach and intestine, but were similar between day and night in both stomachs and intestines. In the stomachs, prey items mostly consisted of caridean shrimps and euphausiids, while the relative contributions of amphipods and unidentifiable items tended to be high in the intestine contents, indicating that the intestines mainly contained content made up of nearly digested and/or hard shell items.
