Abstract
The bulk of diet of the rock sole Lepidopsetta polyxystra in waters of the eastern coast of the northern Kuril Islands and the southern extremity of Kamchatka from September to October 1997 was formed by polychaetes and amphipods (36.8 and 35.1% of the food bolus weight, respectively), which is typical of the feeding of this species, on the whole. The dominant consumption by L. polyxystra of polychaetes is recorded from February to June and of amphipods, from August to December. Polychaetes dominated in the diet of individuals with a length of 16–45 cm and amphipods, in the diet of individuals 46–55 cm long. The feeding migration of L. polyxystra in the study area took place at sites with an increased biomass of the accessible food benthos.
