The Nile Tilapia, Oreochromis niloticus, and the Congo Tilapia, Tilapia rendalli, are important members of the African cichlids, and have been introduced to many Brazilian lakes and reservoirs.
These species exhibit a large feeding flexibility and may modify their habits during their growth.
In the Barra Bonita reservoir, these species are well adapted, representing more than 80% of fish.
This study aimed to analyze ontogenetic variation with regard to the diet of these species in this important r...
