Catfish Special Edition: Microbial Quality of Catfish Nuggets

Testing Flavor Quality of Preharvest Channel Catfish

To avoid marketing fish with environment-related off-flavors, fish must be screened for flavor quality before harvesting. Quantitative chemical analysis is inadequate for flavor quality control because of time constraints, costs involved, and the limited number of odorous compounds that can be detected with available methods. Sensory analysis (taste-testing), which treats trained “tasters” as a...

Susceptibility of channel catfish, blue catfish and channel×blue catfish hybrid to Ichthyophthirius multifiliis

Detection of channel catfish virus DNA in latently infected catfish.

Channel catfish virus (CCV) disease is an acute haemorrhagic disease in juvenile channel catfish (Ictalurus punctatus). While fish that survive primary CCV infection are suspected of being carriers of CCV, little is known concerning CCV latency. In this report, fingerling catfish were infected with CCV by experimental immersion challenge. Infected fish displayed clinical signs of CCV disease, b...

Production of Hybrid Catfish

ferent species is a process called hybridization,with the offspring known as hybrids. Probably the best recognized animal hybrid is the mule,which is a cross between a female horse and a male donkey. Hybrids can have some characteristics of both parents. Breeding hybrids with selected or favored characteristics of each parent is one of the goals of animal husbandry. When a hybrid has characteri...

Efficacy of Formalin as an Egg Disinfectant for Improving Hybrid Catfish (Channel Catfish × Blue Catfish) Hatching Success

—Formalin is currently the only aquaculture drug approved by the U.S. Food and Drug Administration for the control of fungi on the eggs of all finfish. The efficacy of formalin for disinfecting hybrid catfish (channel catfish Ictalurus punctatus 3 blue catfish I. furcatus) eggs was examined and compared with that of three other potential chemotherapeutants. Two experiments were conducted to eva...
