Abstract

The feeding habits of Sebastiscus marmoratus collected from the Western Coastal Waters of Jeju Island between June 2008 and July 2009 were studied based on examination of the stomach contents. A total 254 individuals of S. marmoratus ranged from 13.2 to 29.6cm (mean 20.7cm) in Standard length (SL). S. marmoratus consumed mainly teleosts such as Chromis notata and Sebastes inermis. Its diet also includes shrimps and crabs. The individuals smaller than 15cm SL consumed mainly shrimps, but on the other hand the individuals larger than 25cm SL consumed mainly fishes. The proportion of fish consumption increased with increasing size of S. marmoratus.
