Abstract

In this study, 75 Garra rufa samples were examined to determine the feeding preference. These samples were collected from the tributaries of the Orontes River by using fyke nets, set nets, and electroshock method. G. rufa shows grazer type of nutritional characteristics. Basic nutritional regime was found to rely on phytoplanktons. When importance values of the nutrition sources of this species are analyzed, it is observed that Bacillariophyta is the fundamental group with an IRI (Index of Relative Importance) value of 6800.198. Especially the benthic forms of this family are important nutrient groups. Total nutrients are comprised of Bacillariophyta (65.15%), Cyanophyta (16.21%), and Euglenophyta (0.02%). Organisms of animal origin (Protozoa, Nematoda), although in a very small amount, are also among the nutrient groups of this species.
