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: 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: 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: 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 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: 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.

Summary: In this study, homologous compounds of IL-10 and IL-6 were identified in channel catfish, and their immune responses were analyzed. The expression of IL-10 and IL-6 genes was observed in multiple tissues, with IL-10 highly expressed in the liver and IL-6 highly expressed in the spleen, heart, and gonad. The results suggest that IL-10 and IL-6 are involved in the immune response against pathogens.

Summary: The study showed that dietary myo-inositol at 400 mg/kg significantly improved the weight gain and growth rate of Oreochromis mossambicus under long-term salinity stress, reduced serum glucose and insulin levels, and increased cortisol, sodium, and chloride ion levels. Myo-inositol can also regulate lipid and pyruvic acid metabolism, increase phospholipid synthesis-related mRNA levels, and improve antioxidant properties in fish facing salinity stress.

Summary: The study evaluated the impact of dietary myo-inositol (MI) on growth, antioxidant status, and lipid metabolism in juvenile Chinese mitten crabs fed varying lipid percentages. Results showed that MI supplementation improved lipid accumulation in the crab's body, hepatopancreas, and muscle when fed a high lipid diet, leading to enhanced weight gain and antioxidant enzyme activity while reducing lipid deposition. These effects were attributed to the activation of the IP3R/CaMKK beta/AMPK signaling pathway.

Summary: The study showed that dietary phosphatidylcholine (PC) levels have positive effects on the growth performance, antioxidant capacity, and lipid metabolism of juvenile Eriocheir sinensis. Moderate PC supplementation improved feed conversion ratio, enhanced antioxidant capacity, reduced lipid peroxidation, and promoted protein deposition while reducing total lipid contents in the body. Additionally, appropriate PC levels facilitated the deposition of long-chain polyunsaturated fatty acids in both muscle and hepatopancreas. The study suggested an optimal PC requirement of 2.89% - 2.95% of the diet by weight for juvenile E. sinensis based on weight gain and specific growth rate.

Crabs fed with 6000 IU/kg VD3 showed the highest survival and molting frequency, as well as increased weight gain and antioxidant capacity. Furthermore, VDR was identified as an important regulatory element in molting and innate immunity.

Summary: This study reveals that dietary vitamin A supplementation can significantly improve the growth performance, enhance immunity and antioxidant capacity, promote hepatopancreas health, and alleviate lipid peroxidation in Chinese mitten crab juveniles. Additionally, vitamin A supplementation decreases total lipid content in the whole body and hepatopancreas, as well as triglyceride content in the hepatopancreas and serum. Moreover, gene expression related to immunity, antioxidant capacity, lipolysis and beta-oxidation is up-regulated, while genes associated with lipid synthesis are down-regulated with high dietary vitamin A levels.

Summary: This study investigates the effects of adding myo-inositol (MI) in different vegetable oils diets on the growth, lipid metabolism, and health of Chinese mitten crab. The results show that crabs fed perilla oil (PFO) diet without MI supplementation exhibited the highest growth performance and the lowest lipid levels. Dietary MI reduced lipid deposition in the hepatopancreas and increased expression of genes related to fatty acid uptake and beta-oxidation when crabs were fed palm oil (PO) and olive oil (OO) diets. The study suggests that MI is a functional nutrient that can improve low lipid utilization and inflammatory responses caused by dietary PO and OO in E. sinensis.
