Influence of Channel Catfish and Channel × Blue Catfish Hybrids on Myxozoan Community Composition in Catfish Aquaculture Ponds

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.

Uptake of channel catfish virus from water by channel catfish and bluegills

American Journal of Veterinary Research, 1987
SUMMARY Radiolabeled channel catfish virus entered the gills of juvenile channel catfish (Ictalurus punctatus) and was then concentrated in the gut and the liver over 48 hours. Diminution of radioactivity was not detected in these tissues over the course of the experiment.

Channel Catfish Virus Experiments with Different Strains of Channel Catfish

Transactions of the American Fisheries Society, 1975
Abstract Experimental infections of channel catfish virus were made by feeding virus to six strains of 1-, 2-, and 3-month-old channel catfish from different geographical areas and two hybrid strains. There was no significant difference in mortality between age groups.

Pyridoxine Requirements of Channel Catfish

The Journal of Nutrition, 1979
In 20 and 12 week feeding trials, channel catfish fingerlings were fed purified diets containing five levels (0, 5, 10, 20, and 30 mg/kg) and six levels (0, 1, 2, 5, 10, and 20 mg/kg) of supplemental pyridoxine hydrochloride. Fish fed unsupplemented diets (pyridoxine content of 1.2 mg/kg) were characterized by anoxeria, nervous disorders, tetany ...

Severed Intestine in Channel Catfish

Journal of Wildlife Diseases, 1988
Six cases of severed intestines in farm-raised channel catfish were examined at fish disease diagnostic laboratories in Mississippi and Alabama. This condition has not been reported previously in fish. Affected fish had a 4-7-cm-long intestinal section (hyperemic where it was severed) attached to the stomach.

Productive Infection of Continuous Lines of Channel Catfish Leukocytes by Channel Catfish Virus

Virology, 1993
Channel catfish virus (CCV) undergoes extensive replication in fingerling catfish and establishes latent infection in survivors. Although the site of viral latency in carriers is unknown, a variety of tissues, including leukocytes, have been implicated.

Somatostatins of the Channel Catfish

1985
Pancreatic tissue of the channel catfish (Ictalurus punctatus) contains two somatostatins. The amino acid sequence of a 14-residue containing peptide (SS-14) is identical in sequence and has the same mass ion by fast atom bombardment mass spectrometry as mammalian SS-14.

Response of Adult Channel Catfish to Waterborne Exposures of Channel Catfish Virus

The Progressive Fish-Culturist, 1987
Abstract The response of adult channel catfish (Ictalurus punctatus) to channel catfish virus (CCV) was examined following waterborne exposures to the virus in the laboratory. Adult channel catfish that were survivors of experimental infections as juveniles and reared in the laboratory continued to have anti-CCV neutralizing activity in their plasmas 2

TRIPLOIDY IN CHANNEL CATFISH

Journal of the World Mariculture Society, 1983
ABSTRACTTriploidy was induced in channel catfish (Ictalurus punctatus) by hand stripping eggs from gravid females, fertilization with minced testes from donor males, and cold shocking the eggs at 5°C for one hour beginning 5 minutes post‐fertilization. Hatching success of eggs cold shocked for one hour was 79% compared to 89% in controls.

NEUTRALIZATION OF CHANNEL CATFISH VIRUS BY SERUM OF CHANNEL CATFISH

Journal of Wildlife Diseases, 1973
Sera from 71 adult channel catfish (Ictalurus punctatus), with a history of channel catfish virus (CCV) association, were assayed for CCV neutralization activity. Sixty-seven serum samples had positive CCV neutralization indices. Sera from 10 fish with no known history of CCV exposure, showed no evidence of virus neutralization activity. Viable CCV was
