The feeding habits of scorpion fish, Sebastiscus marmoratus, were studied using 324 specimens collected in the coastal waters of Tongyeong, from January to December, 2009. The size of the specimens ranged from 9.8 to 30.1 cm in standard length (SL). S. marmoratusis was a piscivore that consumed mainly teleosts such as Engraulis japonicus, Clupea pallasi and gobid fishes. Of the fish species Engraulis japonicus was the most preferred prey. Its diet also includes shrimps and crabs. Hermit crabs, polychaetes, bivalves and euphausia were minor preys. Smaller individuals (<13 cm SL) fed mainly on shrimps, crabs and fishes. The proportion of shrimps and crabs decreased as body size increased, whereas the consumption of fishes gradually increased. Fishes accounted for almost stomach contents of larger individuals (more than 19 cm SL). Seasonal changes in the S. marmoratusis diet were significant. Fishes was most common prey during summer, autumn and winter, whereas crabs and shrimps were mainly consumed during spring.
