Maximum and minimum of total length of fish was 350 and 45 mm respectively. Ratio of intestine length to total length (RLG) was 4 for one year old and 2.2 for 5 years old. Ephemeroptera was the most frequent in food item in the Dalaki River but Barbus luteus prefer Plecoptera and Odonata in both Dalaki and Helle rivers. Results showed that this fish has omnivores diet. Biodiversity of macrobentose in the Dalaki River was more than Helle River and in the spring and summer was more than the other times.
