Channel catfish immunoglobulins: Repertoire and expression
Developmental & Comparative Immunology, 2006The channel catfish, Ictalurus punctatus, is widely recognized as an important model for studying immune responses in ectothermic vertebrates. It is one of the few fish species for which defined viable in vitro culture systems have been established and is currently the only fish species from which a variety of functionally distinct clonal leukocyte ...

Vertical transmission of channel catfish virus
American Journal of Veterinary Research, 1988SUMMARY Channel catfish broodfish were examined nondestructively for the presence of channel catfish virus (ccv), using a nucleic acid-probing technique. A dot blot assay was tested and shown to be accurate and rapid in the diagnosis of ccv. Two ccv-positive fish were successfully mated, and fertilized eggs were collected.

Pharmacokinetics and metabolism of fenbendazole in channel catfish
Veterinary Research Communications, 1990Fenbendazole (FBZ) was administered intravenously (1 mg/kg) and orally (5 mg/kg) to catheterized, confined channel catfish. Blood samples were collected for 72 h, and resulting FBZ plasma concentrations were pharmacokinetically modelled. Following intravenous administration t 1/2 alpha was 0.51 h, t 1/2 beta was 16.8 h, body clearance (C1B) was 0.0598 ...

Diencephalic gustatory connections in the channel catfish
Journal of Comparative Neurology, 1993AbstractVertebrate gustatory systems include a tertiary ascending pathway from a secondary gustatory nucleus in the hindbrain to several forebrain nuclei. This connection is prominent in catfish, corresponding to their highly developed sense of taste. Iontophoretic injections of horseradish peroxidase were used to identify the specific target nuclei of

Microsomal estrogen metabolism in channel catfish
Marine Environmental Research, 2004Our goal was to study the involvement of cytochrome P450 genes in estrogen metabolism and the extent to which the potentially carcinogenic 4-hydroxyestradiol metabolite is formed by channel catfish (Ictalurus punctatus; CC). Estradiol metabolism and ethoxyresorufin-O-deethylase (EROD) activity were assessed in several tissues from fish collected from ...

Herpesvirus of channel catfish causes a serious problem in channel catfish fingerlings in the Southern United States and other areas where this species is cultured. The causative agent of channel catfish virus disease (CCVD) is also known as Herpesvirus ictaluri and commonly called channel catfish virus (CCV) (Wolf and Darlington, 1971; Fijan, 1968 ...

Dietary Phosphorus Requirement of Channel Catfish
The Journal of Nutrition, 1982Two experiments were conducted to reevaluate the dietary phosphorus requirement of fingerling channel catfish. Basal diets containing either casein with supplemental inorganic phosphorus and 0.5% total calcium or egg albumin with supplemental inorganic phosphorus and 0.75% total calcium yielded similar requirement data.

Culture of channel catfish (Figure 9.1) accounts for about two-thirds of the commercial aquacultural production in the united states. Sales of catfish (Live Weight) reached 225,000 tons in 1996 (USDA, 1997). Once considered to have primarily a regional appeal as a food, farm-raised catfish are now in national and international markets. Market expansion

Dietary Niacin Requirements for Channel Catfish
The Journal of Nutrition, 1978Channel catfish fingerlings were fed purified diets containing five levels (0, 25, 50, 100, and 150 mg/kg) and six levels (0, 5, 10, 25, 50, and 100 mg/kg) of supplemental niacin in 20 and 12 weeks feeding studies, respectively. The dietary niacin level required to provide maximal growth in rapidly growing channel catfish fingerlings was found to be ...

CONTROL OF Epistylis ON CHANNEL CATFISH IN RACEWAYS
Journal of Wildlife Diseases, 1975An Epistylis outbreak occurred on channel catfish in raceways during two growing seasons. Bioassays of potential control chemicals were conducted. Based on the bioassay results, salt (NaC1) plus formalin and salt alone were the most effective treatment chemicals.
