Abstract

The dietary habits and feeding strategy of Pseudorhombus pentophthalmus were studied based on 484 specimens collected from January to December 2006 off the southeastern coast of Korea. The total length (TL) of the specimens was 8.6-26.8 cm. P. pentophthalmus is a bottom-feeding carnivore that primarily consumes caridean shrimps and secondarily consumes teleosts, but also eats small amounts of crabs, cephalopods, mysids, euphausiids, stomatopods, amphipods, copepods, and isopods. The dietary compositions of P. pentophthalmus significantly differed between size groups during summer, but did not differ between size groups during other seasons, with caridean shrimps dominating the diet of both small and large groups in spring, autumn and winter. Permutational multivariate analysis of variance (PERMANOVA) and analysis of similarities (ANOSIM) revealed significant dietary differences by season, but not by size. Graphical analysis indicated that all size groups of P. pentophthalmus consumed mainly caridean shrimps during all seasons, but teleosts were only important during summer.
