The Tilapia zillii and Nile tilapia which inhabit freshwater, belong to the order perciformes and Cichlidae family. But their nutritional requirements and feeding habits may vary. In this review article using a library research methods and the study of scientific and research articles from various internal and international sources such as SID, Web of Science, Elsevier and Scopus a comprehensive and integrated study has been study to present the nutritional strategy of Tilapia zillii and Nile tilapia in recent decades in Iran and other parts of the world. The results of various studies showed that due to the ability of the Cichlides to use various plant and animal sources in their environment, they can be referred to as detrivorouse, herbivorouse, planktivorouse and predatores. In many articles, herbivory and in many others omnivory are mentioned in these two species. In general, the results of various studies indicated the adaptability of tilapia and showed that feeding biology of tilapia depends on the availability to prey, maturity, season, habitat differences, environmental conditions and fish size. In most studies as the fish size increased the nutritional strategy of these two species shifted from omnivory to herbivory. This suggests that changes in dietary preferences related to size are connected to physiological needs. While seasonal changes in the dietary pattern might be more reflective of opportunistic feeding behavior. Due to seasonal variations in the diet they have been recognized as an opportunistic species in most water resources. In relation to the diet of these two species, it is essential to ensure their optimal growth and performance. It should be noted that these cases can be more valuable to study in relation to aquaculture applications and climate change.
