Summary: An analysis of instrumental texture differences between channel and hybrid catfish fillets revealed significant variations in most texture attributes. Cold-storage type and thickness had some influence on the texture attributes, but the differences between channel and hybrid catfish could still be accurately determined, and TPA analysis provided high levels of differentiation between the two types.

Summary: This study determined the digestibility of specific dietary lipids and fatty acids in Channel Catfish, providing valuable information for lipid selection in commercial diets. The results showed that total lipid digestibility was high, but the digestibility of individual fatty acids varied depending on their source.

Summary: The trematode Bolbophorus damnificus is associated with reduced production and increased mortality in farm-raised catfish in the southeastern United States. Hybrid catfish show lower mortality rates when exposed to comparable numbers of Bolbophorus cercariae compared to channel catfish. Both catfish types exhibited an anemic response to the development of the parasite, but recovered afterwards. The physiological response to B. damnificus infection may not differ between channel and hybrid catfish.

Summary: Hydrolyzed feather meal (HFM) is a protein source in catfish feeds, and it can replace up to 20% of the feed as long as there is a low level of another animal protein. However, complete replacement of poultry-by-product meal (PBM) with HFM was not successful.

Summary: This study determines the mass balance of chlorpheniramine hydrochloride in Channel catfish. The recovery rate of the drug in fish is very low, with most of it being excreted in the form of metabolites. PCBA and ROBH are the main targets for metabolism detection in Channel catfish.

Summary: This study demonstrates that genetic enhancement of the channel catfish's resistance to Edwardsiella ictaluri can be achieved through cecropin transgenesis. The transgenic fish exhibited enhanced disease resistance and improved survival time when challenged with the bacteria. The growth rates of transgenic and non-transgenic fish were not different, indicating that the transgene did not affect the overall growth of the fish.

Summary: In this study, we identified the complete repertoire of IFNs and IFN receptor genes in channel catfish. We found 16 type I IFN genes representing six previously defined subgroups, as well as two type II IFN genes and their respective receptors. Our findings provide a comprehensive resource for future research on the innate antiviral immunity of channel catfish.

Summary: This study revealed that salinity stress has a significant impact on the growth, survival, and antioxidant system of channel catfish. It was found that amino acid metabolism genes were significantly up-regulated in the low salt stress group, immune response genes were significantly up-regulated in the high salt stress group, and fatty acid metabolism genes were significantly up-regulated in both groups.

Summary: The study showed that dietary trans-cinnamaldehyde (TC) can increase the activity of superoxide dismutase (SOD) and decrease the concentration of malondialdehyde (MDA) in hepatic tissue of channel catfish. Additionally, after infection with Edwardsiella ictaluri, catfish fed with TC demonstrated significantly increased antioxidant defense responses on days 1, 6, and 14 post-infection. However, there were no significant differences in the activities/concentrations of catalase (CAT), reduced glutathione (GSH), nitric oxide (NO), and MDA between the TC and control groups.

Summary: GH cDNA constructs were transferred to channel catfish via electroporation, resulting in increased growth rate in F-1 individuals. Transgenic channel catfish exhibited larger body sizes compared to non-transgenic full-siblings. The family effect played a significant role in the growth response to the gene transfer.

Summary: This study investigated the physiological responses of channel catfish reared under different stocking densities. The results showed that high stocking density caused chronic stress in the catfish, leading to variations in biochemical and immune functions.

Summary: This study identified and analyzed seven Dmrt genes from the channel catfish genome, providing insights into their role in sex determination and differentiation. Tissue distribution and expression pattern analysis revealed their involvement in the development of reproductive organs in channel catfish. The findings highlight the importance of the Dmrt gene family in this species.

Summary: This study investigated the effects of CRISPR/Cas9 knockout of the myostatin gene in channel catfish. The results showed that gene-edited channel catfish exhibited high mutation and inheritance rates, as well as improved growth and disease resistance compared to control groups. Therefore, the use of MSTN gene-edited channel catfish is of great importance for commercial farms.

Summary: In this study, the levels of serum corticosterone, cortisol, and glucose were measured to evaluate the responses of fish to seven common stressors. The results showed that corticosterone and cortisol exhibited different patterns of dynamic changes, and glucose levels were influenced by both hormones. Corticosterone seemed to respond to stress earlier than cortisol and together they regulated glucose levels to cope with stress.
