By-products of the processing of catfish have become available as a feed ingredient. Five samples were obtained and evaluated for nutrient content so as to provide the nutritionist with a baseline of information with which to consider possible use of this ingredient. The most unique nutritional features of catfish meal are high levels of protein (60%) combined with calcium (8%) and phosphorus (4.2%). Essential amino acids as percentages of crude protein tend to be somewhat lower than other fish meals. Average TME_n was 2,773 kcal/kg (94% DM).

Key Words: Catfish meal • fatty acids • metabolizable energy • protein
