Channel Catfish Ictalurus punctatus
We used a two-compartment, clearance volume-based model to examine rubidium and cesium Ž . pharmacokinetics in channel catfish Ictalurus punctatus after intravascular administration. We compared the apparent volumes of distribution in the central and peripheral compartments and the intercompartmental and whole-body clearances of both metals at 20.0 8C and 27.5 8C. Biological half-times of Rb we...
متن کاملInteraction between dietary levels of iron and vitamin C on growth, hematology, immune ž response and resistance of channel catfish Ictalurus / punctatus to Edwardsiella ictaluri challenge
Nine egg-white-based diets supplemented with three levels of vitamin C from L-ascorbyl-2Ž . polyphosphate 0, 50 and 3000 mgrkg for each of the three levels of iron from iron methionine Ž . 0, 30 and 300 mgrkg were each fed to juvenile channel catfish in triplicate aquaria twice daily to apparent satiation for 14 weeks. Fish fed with iron-deficient diets had decreased weight gain, feed conversio...
متن کاملEffects of dietary arginine on endocrine growth factors of channel catfish, Ictalurus punctatus.
Thyroid (TH) and growth (GH) hormones, and insulin-like growth factor I (IGF-I) are anabolic regulators in fish and responsive to nutrient intake. A study was conducted to determine if previously reported growth effects of dietary arginine (ARG) in channel catfish were related to the activation of endocrine axes. In a first experiment, catfish were fed incremental levels of ARG (0.5 - 4% of die...
متن کاملEffect of handling stress on susceptibility of channel catfish Ictalurus punctatus to Ichthyophthirius multifiliis and channel catfish virus infection
A quantitative bioassay employing immersion exposure was developed for the infection of channel catfish Ictalurus punctatus with the protozoan parasite Ichthyophthirius multifiliis, commonly referred to as ich. This bioassay as well as waterborne challenge of channel catfish with channel catfish virus (CCV) was used to investigate the effect of confinement stress on the sensitivity of the fish ...
متن کاملIron Methionine and Iron Sulfate as Sources of Dietary Iron for Channel Catfish Ictalurus punctatus
The dietary iron requirement for normal growth and optimum hematological values and bioavailability was determined for channel catfish Ictalurus punctatus fingerlings using eggwhite based diets supplemented with 0,5,10,20,60, and 180-mg ironkg from iron methionine or 20, 60, and 180-mg ironkg from iron sulfate. The basal diet which contained 9.2-mg ironkg, 34% crude protein and 3.1 kcal of dige...
