This monograph, therefore, provides new insight regarding to the biology of Nile Tilapia in such dynamic ecosystem. Juvenile tilapia are omnivorous, meaning that they are opportunistic feeders that ingest both plants and animals without specialization. The Nile tilapia (Oreochromis niloticus) is a species of tilapia, a cichlid fish native to the northern half of Africa and the Levante area, including Jordan, Palestine, Israel, and Lebanon.

The food composition may also vary depending on size of the fish, maturity, environmental condition and habitat types (Karl et al., 2001).Various authors have studied the food and feeding habits of Nile tilapia in African water bodies including Nigeria (Engdaw et al.,2013;Tefera,1993;Teferi et al., 2000; Wakjira, 2013 and Teame et al.,2016).
