Factors Affecting Voluntary Food Consumption By Channel Catfish

Nutritional and physical properties of the diet, management, and environment affect voluntary food consumption by channel catfish (lctalurus punctatus). Laboratory studies in which channel catfish were fed twice daily to satiation with semipurified diets containing various ratios of protein and digestihle. energy indicated that food intake was directly proportional to calorie density in the diet but independent of protein density until the protein percentage exceeded 45. Protein levels above 45% caused reduced food intake. Pond experiments in which channel catfish were fed to satiation...
