Summary: This study found that knockout of the mstnb gene in Pelteobagrus fulvidraco resulted in a reduction in the number of vertebrae, body length, and an increase in the number and density of osteocytes. It highlights the importance of comprehensive analysis of knockout effects and the need for sufficient study on the function of certain genes when using genome editing technology to breed new lines.

Summary: The study showed that adding B. velezensis YFI-E109 to hybrid yellow catfish diets can improve growth, liver and gut health, and reshape the gut microbiome. However, excessive supplementation of the probiotic may reduce its beneficial effects, indicating the need for optimal dosage for maximum benefits.

Summary: This study analyzed the transcriptomic spectrum of yellow catfish head kidney challenged by Vibrio cholerae using high-throughput sequencing methods. A total of 45,544 unique transcript fragments and 674 differentially expressed genes were identified. Functional analysis showed that these differentially expressed genes were involved in immune response, response to external stimuli, and regulation of immune-related pathways. Real-time quantitative reverse transcription-PCR results confirmed the upregulation of 10 immune response genes after 6 hours of V. cholerae challenge. Overall, this study provides insights into the defense mechanisms and immune system responses of yellow catfish to bacterial challenges.

Summary: The purpose of this study was to investigate the growth performance of yellow catfish under chronic low ammonia exposure and determine the upper limit of growth tolerance for ammonia. The results showed that the growth performance of yellow catfish significantly declined when ammonia level exceeded 1.25 mg/L TAN. It is recommended that juvenile yellow catfish not be exposed to ammonia concentrations >1.25 mg/L TAN for prolonged periods of time.

Summary: Hypoxia has become a significant issue in aquatic environments and aquaculture systems. In this study, a hypoxia-tolerant hybrid fish strain was generated through artificial insemination. The hybrid exhibited higher hatching rate, improved hypoxia-tolerance, and evidence of tissue remodeling in response to hypoxia. Rapid response of HIF-related genes and activation of antioxidant enzymes were observed in the hybrid. This study provides an alternative method for generating hypoxia-tolerant fish strains through hybridization breeding in aquaculture.

Summary: In this study, it was found that the IL-17N gene in teleosts played an important role in preventing pathogen invasion. The IL-17N protein promoted inflammatory responses and enhanced immune cell phagocytosis and chemotaxis. It also regulated inflammatory responses through the NF-κB and MAPK signaling pathways.

Summary: The study found that microcystin-LR induces the expression of an inflammatory factor, PfHMGB1, in juvenile yellow catfish, which plays a crucial role in the liver damage caused by MC-LR. PfHMGB1 is associated with inflammatory responses and DNA binding, while anti-PfHMGB1 can mitigate the hepatotoxicity of MC-LR.

Summary: This study analyzed the bacterial community characteristics of the Pelteobagrus fulvidraco integrated multi-trophic aquaculture system (YPS) and the water environment using high throughput sequencing technology and water analysis. The results showed that the system met the growth requirements of Pelteobagrus fulvidraco and different dominant bacterial genera were observed in different seasons. The study provides a theoretical basis for regulating the YPS.

Summary: Fish are at high risk of ammonia exposure in aquaculture systems, which can lead to increased susceptibility to diseases. The study investigated the role of argininosuccinate synthetase (ASS) in regulating urea synthesis and nitric oxide synthesis in fish. The results showed a correlation between ASS expression and disease outbreak. The targeted regulation of ASS improved immune response in fish under ammonia stress.

Summary: This study aimed to investigate the effect of N-carbamylglutamate (NCG) supplementation on ammonia tolerance in yellow catfish. The results showed that NCG supplementation can improve the ammonia tolerance of yellow catfish, and the activation of the urea cycle may be related to the activity of argininosuccinate synthetase (ASS).
