The objective of this study was to chemically characterize both channel and hybrid catfish parts including heads, frames, viscera, skin, and fillet trimming mince. Triplicate samples of channel and hybrid catfish byproduct parts were obtained from a large commercial catfish processor and analyzed for percent moisture, lipid, protein, ash, and amino acid and fatty acid profiles were determined. ...

Diplostomoid digenean metacercariae have caused widescale mortalities of channel catfish, Ictalurus punctatus (Rafinesque), at aquaculture farms in Louisiana, Mississippi and Arkansas, USA. Originally, based on a tentative diagnosis, the industry considered the primary harmful agent to be an introduced species from Europe, Bolbophorus confusus (Krause, 1914), frequently reported from the Americ...

Catfish is the major aquaculture species in the United States. The hybrid catfish produced by crossing channel catfish females with blue catfish males exhibit a number of desirable production traits, but their mass production has been difficult. To introduce desirable genes from blue catfish into channel catfish through introgression, a genetic linkage map is helpful. In this project, a genetic...

Musty "off-flavor" in pond-cultured channel catfish (Ictalurus punctatus) costs the catfish production industry in the United States at least 30 million US dollars annually. The cyanobacterium Oscillatoria perornata (Skuja) is credited with being the major cause of musty off-flavor in farm-raised catfish in Mississippi. The herbicides diuron and copper sulfate, currently used by catfish produce...

CD63, known as lysosome associated membrane protein 3 (LAMP-3), is a member of the tetraspanin integral membrane protein family. This protein plays many important roles in immuno-physiological functions. In this communication, we report the identification, characterization, and expression analysis of the channel catfish CD63 transcript. The complete nucleic acid sequence of channel catfish CD63...

This study determined the lipid content and FA composition of muscle and a mixture of muscle and viscera from Korean catfish as well as lipid oxidation and hydrolysis. Lipid content and FA compositions in Korean catfish, which were purchased every month or two during September 1999–July 2000, were analyzed. Lipid oxidation and hydrolysis were determined as PV, thiobarbituric acid value, and FFA...

In aquaponics and circular multitrophic food production systems, dietary protein source, as well fish species choice, particularly in cases of different nutritional physiology, could be factors affecting excreted nutrient profiles. Accordingly, growth performance, dissolved accumulation feces profiles were evaluated for African catfish (Clarias gariepinus) reared recirculating aquaculture syste...

Channel catfish virus disease (CCVD) is a highly pathogenic herpesvirus disease of cultured channel catfish, Ictalurus punctatus, fry and fingerlings. The disease is confined to the southern United States, but occurs sporadically in other areas where young channel catfish are intensively cultured. Blue catfish, I. furcatus, have been experimentally infected with CCV, but other ictalurids appear...

The nematode parasites of 30 spot-tailed robbers, Brycinus imberi, five tiger-fish, Hydrocynus vittatus, 77 large-scaled yellowfish. Barbus marequensis, two mudsuckers, Labeo molybdinus, 114 catfish, Clarias gariepinus, 46 silver barbel, Schilbe intermedius, 66 squeakers, Synodontis zambezensis, three eels, Anguilla spp., 83 Mozambique bream, Oreochromis mossambicus, 81 red-breasted bream, Tila...

Chemokines are a large family of chemotactic cytokines playing crucial roles in the innate immune response. CC chemokines constitute the largest subfamily of chemokines, with 28 CC chemokines identified from mammalian species. However, the status of CC chemokines in teleosts is yet to be determined. We previously identified 26 catfish CC chemokine cDNAs from catfish. In this study, we isolated ...
