Food preferences of Chinese carps fry Hypophthalmichthys molitrix (silver carp SC), Ctenopharyngodon idella (grass carp GC) and Cyprinus Carpio (common carp CC) in the earthen ponds of Deroua fisheries station (Fkih Ben Saleh; Morocco) was investigated during 2014 season. The Lauzanne food index combining the occurrence percentages, volumes and the abundance index was used to assess the relative importance of different food items which are identified. The results showed that fry of class one (0.6 to 0.83 cm), consumed especially Chlorococcales and Diatomophyceae, those of class two (0.84 to 2.30 cm) preferentially consumed copepod larvae and insect larvae. The feeding behavior of fry returns to the normal diet at the class three (2.40 to 3.40 cm), when the diet of fry becomes dominated by Chlorococcales (Scenedesmus crassus, Coelastrum reticulatum var. Reticulatum) and Diatomophyceae (Nitzschia amphibia). When fry diet of SC is dominated by Scenedesmus crassus, Coelastrum reticulatum var. Reticulatum and Nitzschia amphibia, GC consumed especially Spirogyra variants and Spirogyra majuscula and CC mainly feed on plant seeds.
