Feed additives are compounds incorporated in the diet for specific purposes other than matching up with the nutrient requirements, including the improvement of the wellbeing of the cultured organism, and enhancement of culture environment, quality of fish as a final product, and physical and chemical characteristics of the feed. A good deal of rese...

In the previous edition, this chapter was part of the diet formulation and manufacture chapter. In this edition, a separate chapter is devoted to the topic. There are two reasons for this change. First, alternative ingredients increasingly used in fish feeds are less familiar, so identifying appropriate chemical tests to assess quality of alternati...

A great deal of research has been focused on feed additives that can boost the immune system of cultured fish since the food and drug administration (FDA) banned the use of antibiotics as feed supplementations in 2017.
