Online published on 1 November, 2018. Abstract The present investigation represents the first study on feeding and parasites of Carasobarbus luteus from Euphrates River in Samawah city during the period from October 2017 to June 2018 from three stations to provided predictive equation for the relationships between food consumption and parasitic infection. The current study was showed that there are five nutrients that can be taken up by fish. Plant parts were of great importance in feeding Carasobarbus luteus fish, with the highest value of Index of relative importance IRI% (32.605) followed by crustaceans (22.349), insects (20.33), algae (18.916) and organic detritus record lowest value (17779) that means the fish of this study belong to Omnivorous group. Statistical analysis indicated no significant differences are found in food items. Indicate that male and female Carasobarbus luteus fish are infected with Contracaecum sp larvae in the third stage, the statistical analysis showed that there are significant differences in the incidence of Contracaecum sp larvae parasites among males and females. The highest incidence was recorded in females compared to male fish, the total mean for the intensity of infection was (1.0667, 1.633) in both sexes respectively Top Keywords Algae, Feeding habits, Nematoda worm, parasitic infections.
