  Feed is the main cost to aquaculture production, management practices, and feeding strategies are aimed at optimizing feed intake and efficiency. Knowledge about feeding protocols and behavior habits may be of an interest for optimization of aquaculture production, reducing aquaculture waste output and to achieve sustainability. This study investigated trends based on daily feeding schedules. Two growth trials were conducted to investigate the effect of day to day mixed feeding schedules on the growth performance of Nile tilapia. Three experimental isocaloric diets of low (A; 20%), regular feeding (RF; 30%) and high (B; 40%) protein levels were prepared. In the first trial, fish were continuously fed a normal protein diet (RF-30%), alternate feeding of a 1-day diet A; followed by a 1-day diet B (1A/1B) and alternate feeding of 2-day diet A; followed by a 2-day diet B (2A/2B) and a 3-d..
