Effects of Various Dietary Carotenoid Pigments on Fillet Appearance and Pigment Absorption in Channel Catfish, Ictalurus punctatus
Channel catfish can accumulate yellow pigments LUT and ZEA and red or pink pigments CAN and AST in the flesh, resulting in yellow coloration, and the yellow pigment BCA does not appear to deposit in skin or flesh at levels sufficient to alter the coloration.
Effects of various corn distillers by‐products on growth, feed efficiency, and body composition of channel catfish, Ictalurus punctatus
The presence of distillers solubles in the diet appears to increase diet consumption, weight gain, and FER over the control diets with or without additional fat.
Detection of Off-Flavor in Catfish Using a Conducting Polymer Electronic-Nose Technology
The Aromascan A32S conducting polymer electronic nose was evaluated for the capability of detecting the presence of off-flavor malodorous compounds in catfish meat fillets to assess meat quality for
Evaluation of corn distillers dried grains with solubles and brewers yeast in diets for channel catfish Ictalurus punctatus (Rafinesque)
The EDDGS could potentially be used at high levels as a substitution for soybean meal without causing yellow pigment deposition in cat¢sh £esh, provided that the ethanol extraction process is proven economical.
Nutrient Characteristics of Pond-Raised Channel Catfish
The nutrient content of farm-raised channel catfish muscle tissue has been published in part in various research articles over the years; the latest and most comprehensive publication was that of Nettleton et al. (1990), and this study was conducted to update information on nutrient content.
Apparent digestibility of alternative plant-protein feedstuffs for channel catfish, Ictalurus punctatus (Rafinesque)
Results from the present study can be useful in formulating cost-effective catfish feeds using these alternative feedstuffs, including corn gluten feed, corn germ meal, distillers dried grains with solubles, and canola meal.
Evaluation of Glycerol from Biodiesel Production as a Feed Ingredient for Channel Catfish, Ictalurus punctatus
It appears that channel catfish can utilize about 10% glycerol in the diet without adverse effects on feed consumption, weight gain, feed efficiency ratio, hemoglobin, hepatosomatic index, and liver lipid.
Evaluation of cottonseed meal derived from genetically modified cotton as feed ingredients for channel catfish, Ictalurus punctatus
Results from the present study demonstrate that these GM cottonseed meals are nutritionally equivalent to conventional non-GM cotton varieties when fed to catfish at 20% of the diet.
Clearance of Yellow Pigments Lutein and Zeathanxin in Channel Catfish, Ictalurus punctatus, Reared at Different Water Temperatures
Results demonstrate that about 8 wk were needed for catfish to “purge” most of yellow pigment at warm temperatures (20 and 30 C) and a longer period of time (> 12 wk) was required at 10 C.
Effects of Dietary Protein Concentration and Feeding Regimen on Channel Catfish, Ictalurus punctatus, Production
Results suggest that response of channel catfish to dietary protein levels depends on whether the fish were fed daily or EOD, and feeding EOD to satiation improved feed efficiency and required less aeration compared with fish fed daily but also reduced net production and processing yield.
