Abstract

The feeding habits of olive flounder, Paralichthys olivaceus were studied using 126 specimens collected from coastal waters off Taean, Korea from April 2008 to March 2009. The total lengths of P. olivaceus ranged from 16.7 to 40.6 cm. P. olivaceus was a piscivore that consumed mainly fishes. The diet also included small quantities of shrimps, cephalopods, polychaetes and mysids. Although, P. olivaceus mainly consumed fishes of all size classes, some degree of change in diet composition was found; i.e. after fishes, smaller individuals fed more on shrimps, whereas larger individuals consumed more cephalopods.
