Microbial Diversity Affects the Cold Tolerance of Red Swamp Crayfish (Procambarus clarkii) by Regulating Histamine Metabolism.

ABSTRACT: The red swamp crayfish (Procambarus clarkii) is one of the important freshwater aquaculture species in China, but its growth and development are greatly affected by temperature, which makes it difficult to expand its aquaculture range to the northern regions of China. The composition of gut microbes plays a vital role in resisting environmental pressure, and is also an important driving factor for amino acid metabolism in the body. However, little is known about the relationship between microorganisms, metabolism, and cold-resistance ability of P. clarkii. In this study, we performed the cold-resistance and antioxidant ability test, gut microbiota diversity analysis, quantitative analysis of histamine, and bioinformatics analysis of histamine receptor (HR) family on P. clarkii.
