Similar results have also been obtained in zebrafish (Danio rerio) (Li et al, 2012), Cyprinus carpio (Gracey et al, 2004), and yellow drum (Nibeaal biflflora) (Xu et al, 2018), when these species were subjected to cold stress. Therefore, the establishment of a low-temperature adaptive phenotype requires alteration of RNA splicing, modification, and degradation to prevent the formation of RNA secondary structure under low-temperature conditions (Li et al, 2012).…”

“…Therefore, the establishment of a low-temperature adaptive phenotype requires alteration of RNA splicing, modification, and degradation to prevent the formation of RNA secondary structure under low-temperature conditions ( Li et al, 2012 ). Ribonucleoproteins are the factory for protein synthesis, and the upregulated expression of ribosomal biogenic genes may be a compensatory response to promote protein synthesis at low temperatures ( Li et al, 2012 ), and has been observed in zebrafish ( Li et al, 2012 ), as well as in yellow catfish in our study.…”

The yellow catfish (P. fulvidraco), as one of the economically-relevant freshwater fish found in China, cannot tolerate cold stress. Understanding the physiological and biochemical mechanisms under cold stress may provide insights for improving yellow catfish management in the cold. Therefore, we investigated the metabolic and intestinal microbiota changes in cold stress in response to induced cold stress. We found that cold stress in yellow catfish lead to a significant increase in the consumption of glucose and triglycerides, as well as increased use of cholesterol as an alternate energy source. Moreover, cold stress also activated several significant biological processes in the fish such as thermogenesis, oxidative phosphorylation, the spliceosome machinery, RNA transport, protein processing that occurs in the ER, and purine and pyrimidine metabolism pathways involved in energy production. On the other hand, many other mechanisms like insulin resistance, starch and sucrose metabolism, and the glyoxylate and dicarboxylate metabolic pathways that also served as energy production pathways were weakened. Furthermore, organic acids and their derivatives as well as the lipids and lipid-like molecules were mainly altered in cold stress; prenol lipids, steroids, and their derivatives were significantly upregulated, while fatty acyls and glycerophospholipids were significantly downregulated. Transcriptomic and metabolomic integrated analysis data revealed that carbohydrate metabolism, lipid metabolism, amino acid metabolism, and nucleotide metabolism were involved in cold stress resistance. In addition, the intestinal microbiota abundance was also reduce and the pathogenic bacteria of plesiomonas was rapidly appreciation, which suggesting that cold stress also impaired intestinal health. This research study could offer insights into winter management or the development of feed to promote cold resistance in yellow catfish.
