(Report) by "The American Midland Naturalist"; Biological sciences Earth sciences Animal nutrition Analysis Catfishes Research Habitat conservation Two experiments were conducted in aquaria to determine the minimum dietary selenium requirement of fingerling channel catfish (Ictalurus punctatus).Casein-gelatin diets containing graded levels of supplemental selenium (as Na 2 SeO 3) ranging from 0 to 15 mg/kg were fed to catfish for 15 weeks in experiment 1 to broadly define their selenium requirement and toxicity levels. importance of specific prey items in diets. One study found insects belonging to 50 different families in the stomachs of channel catfish in the Des Moines River, indicating an extremely variable diet. Five diets containing 0, 50, 100, 200 and 300 g frass per kg diet were fed to channel catfish (5.24 ± 0.04 g) in quadruplicate aquaria to apparent satiation twice daily. Moreover, increasing dietary protein level in the diet of channel catfish broodstock from 32 to 42 percent did not influence spawning, fecundity or fertilization, but affected egg size and biochemical composition of the eggs (Quintero et al., 2009). Three experiments were conducted to evaluate the need for supplemental phosphorus in the diet of channel catfish Ictalurus punctatus as well as to compare dicalcium phosphate and defluorinated phosphate as sources of supplemental phosphorus. Off-channel habitats appeared more suitable for channel catfish. But when more pro-tein is provided by the diet than fish can use for growth, the excess The results of-these research projects should help producers and pro-cessors modify management practices to Best Bait for Channel Catfish.
