• The dynamics of trophic relationships between prey and predator of yellowfin sole and influence of bottom water temperature upon them were examined in the eastern Bering Sea during summers from 1979 to 1984. Yellowfin sole were classified by sex and fork length. Mutual occurrences between yellowfin sole (male 11-25cm, female 16-20, 26-30cm) and capelin were found to vary with bottom temperature significantly. Area overlaps between yellowfin sole and most species were not correlated with ambient temperature. This fact suggests that mutual occurrence is due to other biological or physical considerations related to the intrinsic requirements of each species. This study has elucidated that some coexistences of prey and predators which facilitate predation to a greater degree were affected by bottom water temperature.
