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 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 کاملPre- and postprandial changes in orexigenic and anorexigenic factors in channel catfish (Ictalurus punctatus).
Ghrelin (GRLN), cocaine and amphetamine regulated transcript (CART), neuropeptide Y (NPY), and cholecystokinin (CCK) are neuropeptides involved in the regulation of appetite and feeding in vertebrates. We examined pre- and postprandial changes in the expression of plasma GHRL and mRNAs encoding GRLN, CART, NPY, and CCK in channel catfish. Fish were entrained to eat at 0900 h for 2 weeks. Fish w...
متن کاملIdentification and Characterization of Full-Length cDNAs in Channel Catfish (Ictalurus punctatus) and Blue Catfish (Ictalurus furcatus)
BACKGROUND Genome annotation projects, gene functional studies, and phylogenetic analyses for a given organism all greatly benefit from access to a validated full-length cDNA resource. While increasingly common in model species, full-length cDNA resources in aquaculture species are scarce. METHODOLOGY AND PRINCIPAL FINDINGS Through in silico analysis of catfish (Ictalurus spp.) ESTs, a total ...
متن کاملHormonal Control of Osmoregulation in a Stenohaline Catfish, Ictalurus Punctatus
When channel catfish (lchtalurus punctatus) in fresh water (FW) were hypophysectomized, plasma osmolality decreased significantly after 24 hrs, and the maximum reduction was seen after 2 days. When they were transferred from FW to dilute seawater (20-40% SW), plasma osmolality of the sham-operated fish was consistently higher than the osmolality of the environmental water, whereas the osmolalit...
