Feeding habits of released Sebastes inermis obtained in daily and monthly collections from August 2007 to December 2007 in coastal waters off Jam Island in Jinhae Bay, Korea were assessed. A total 151 individuals of S. inermis (6.3-9.7cm TL) were recaptured during the study period. Initial food intake of released S. inermis occurred within three days of released. Stomach content index increased with time, however, the percentage of stomachs devoid of contents decreased. Sebastes inermis mainly consumed gammarid and caprellid amphipods, gastropods and mysids. Diet also included small quantities of bivalves, shrimps, copepods and ostracods. Amphipods were mainly consumed at all size groups and consumption of gastropods, bivalves and shrimps increased with increasing fish size.
