Abstract
When channel catfish fingerlings were fed semipurified diets supplemented with monobasic sodium phosphate, their minimum requirement of dietary phosphorus for satisfactory growth and bone mineralization was approximately 0.45%. The addition of calcium (calcium carbonate) to a phosphorus‐supplemented diet increased growth rate slightly but not significantly. Availability of phosphorus for channel catfish, as determined by net absorption from the digestive tract, was 90‐94% for monosodium and monocalcium phosphate, 65% for dicalcium phosphate (feed‐grade), 40% for fish meal, 50‐54% for soybean meal, and 25‐28% for cereal products.Keywords
