Utilization of Casein and Soybean Protein by Channel Catfish, Lctalurus Punctatus (Rafinesque)
The growth rate data indicated that diets containing casein and the protein combination produced approximately equal growth and that both of these protein sources produced better growth than soybean protein alone. Fish receiving diets containing 30 per cent protein gained at a significantly higher rate than fish receiving diets containing five per cent protein. The relative order of growth rates for the three sources of protein was the same at both levels of protein in the diet.
