Abstract: In this study, 239 perch which had been caught between May 1998 and December 2000 from Derbent Dam Lake with a number of different nets, shockers and tackles were examined. The organisms obtained after analyzing the perch stomach contents patterns were examined by means of the Geometric Index of Importance (GII). As a result, a total of 27 food items (19 of which were plant and eight animal) were found in the stomach contents. The percentage of plant diet was 6% and that of animal diet was 94%.
