다국어 초록 (Multilingual Abstract)

The feeding habits of Repomucenus lunatus were studied using 232 specimens collected from January to December 2006 in the coastal waters off Gori, Korea. The size of R. lunatus ranged from 4.7 to 14.0cm in standard length (SL). R. lunatus was a bottom- feeding camivore which consumed mainly amphipids and polychaeres. lts diet also included small quantities of shrimps, cumaceans, bivalvies, gastropods, cravbl, copeods,euphausia, mysids,stomatopods, ostracods and sipunculides. Amphioks were eaaten predominantly for the smallest size class. The proportions of polychaetes increased qrakually with increasing fish size and large size class of R. lunarus mainly consumed poly-chdetes. The feeding strategy graphical method revealed that R. lunatus is a specialized feeder. The mean number and weight of preys per stomach of alrger size cl asses were higher than those of smaller size classes. The mean weight of preys per stomach ontogneeetically changed with size classes.
