ABSTRACT
Aquatic animal nutrition is a relatively new science. Although it has many similarities to terrestrial animal nutrition, fi sh nutrition research is confronted with a wide variety of challenges not encountered in research on terrestrial animals. These challenges are primarily due to the aquatic media that require special considerations related to the delivery of nutrients, monitoring of food intake, collection and quantifi cation of waste products, and the unique physiology of various species of fi sh (NRC 2011).
