Background: The gut microbiota is very important for maintaining the homeostasis and health of crustaceans. Many factors affect the gut microbiota of crustaceans, one of which is temperature. However, it is currently unclear how temperature affects the gut microbiota and metabolites of .
Methods: Using metagenomic sequencing and gas chromatography-mass spectrometry (GC-MS) techniques, the gut microbiota and metabolites of from Hubei (HB), Jiangsu (JS), Shandong (SD), and Zhejiang (ZJ) in China were investigated.
Results: Under the impact of temperature, the gut microbiota and metabolites of exhibit a specific trend of change. The primary pathogenic bacteria affecting are , and , which are affected by temperature. Two metabolites, namely, sugars and amino acids, are regulated by temperature.
Implication: This study demonstrated that the gut microbiota and gut metabolites of were considerably affected by temperature. It provides a theoretical basis for the systematic study of and provides a basis for a healthy culture of .
