Thiamin Requirement of Channel Catfish Fingerlings
The Journal of Nutrition, 1978In separate 20 and 12 week feeding studies, channel catfish fingerlings were fed semipurified diets containing five levels (0, 2.5, 5.0, 10.0 and 15.0 mg/kg) and six levels (0, 0.5, 1.0, 2.5, 5.0 and 10.0 mg/kg) of supplemented thiamin hydrochloride respectively.

Proteolytic fragmentation of channel catfish antibodies
Developmental & Comparative Immunology, 1991Specifically purified anti-DNP antibodies from channel catfish were digested with pepsin or trypsin under various conditions and the resultant fragments analyzed in terms of their physico- and immunochemical properties. The results indicated that pepsinolysis of channel catfish antibodies to small peptides was exceedingly rapid and failed to yield ...

North American Journal of Aquaculture, 2023
Abstract The myxozoan Henneguya ictaluri is cited as the cause of proliferative gill disease (PGD) in Channel Catfish Ictalurus punctatus and Channel × Blue Catfish I. furcatus hybrids. Differences in host susceptibility result in decreased transmission rates, reduced sporogenesis, and lesser incidence of PGD in hybrid catfish.

1998
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

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 ...

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 ...

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.

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.

Ontogeny of channel catfish lymphoid organs
Veterinary Immunology and Immunopathology, 2001Previously, we showed that catfish could not mount a detectable antibody response after bacterial exposure until 21 days post-hatch (ph). In order to evaluate the changes associated with the development of a functional humoral response, we evaluated the temporal and spatial distribution of immune cell populations in developing catfish.
