The food of Cyprinus carpio has been investigated in Al-latifiyah fish farming during April-November 1986. Cladocera, Copepoda, Rotifera and Ostracoda constituted the food of Carp, zooplankton samples were taken at the same time and in the same location where the fish were sampled, and the concentration of different food organisms studied. Electivity of the different food organisms was studied from Ivlev's index, which showed positive electivity, e.g. Alona costata and negative for Cyclops. In studying predator prey relationships, Alona was chosen as the "standard prey", being the most abundant of all food organisms in the diet of Carp. Eight species comprise cladoceran fauna of fish stomach, Ceriodaphnia cornuta, Macrothrix laticornis.
