Technical Abstract: Though the various dietary nutrients are the primary concerns of nutritionists when formulating feeds for intensively cultured tilapia, the inclusion of dietary components that do not have nutritional value can have profound effects on the performance of fish fed these diets. These components may be added to address physiological, immunological or health concerns of the aquaculturists (e.g. enzymes, hormones, immuno-enhancers, probiotics, antibiotics), to improve pellet quality (pellet binders), to increase feed palatability (feeding stimulants), to improve flesh color (carotenoids), or to lengthen the shelf-life of the diets (anti-mold and antioxidants). This chapter provides detail discussion on the use of these nonnutrient components in tilapia diets.
