Advances in multi-omics study of environmental stress in fish during temporary breading and transportation

The long-distance live fish transportation technology is the main method used in China's 'South-to-North Fish Transportation' program. During transportation process, fish are subjected to various environmental factors such as low temperature, salinity fluctuations, alkaline stress, etc.. Combined with multi-omics integrated research methods, we conducted a multidimensional analysis of the stress response in fish transportation, including identification of differentially expressed genes, proteins and metabolites, as well as an analysis of regulatory networks and biomarkers associated with the stress response. These studies help to understand the health status of fish during transportation, optimization of temporary rearing and transportation conditions, as well as improvement of the quality and survival rate of live fish. The paper provides an overview of the recent advancements in omics research on various stress responses in fish during transportation, and provides a reference for the precise regulation of environmental indicators and in-depth investigation of the underlying mechanisms of stress response in live fish transportation.
