| Summary: | Shrimp is closely associated with different microbial populations of the gut and the environment, particularly of the
water. Despite significant microbiome research in shrimp, a direct relationship between the shrimp's gut microbiota and the
habitat environment remains unclear. The bacterial profiles of the shrimp intestine and its aqueous environment were compared
by compiling data from earlier research to characterize the dynamic interaction between shrimp and habitat. According to the
integrated analysis, shrimp, water, and sediment all had significant operational taxonomic units (OTUs), with shrimp intestine
having less OTUs and sediment having more. Furthermore, 66 biological activities were shown to be common in shrimp and
water bacteria, including nitrate reduction, methylotrophy, methanol oxidation, intracellular parasites, human infectious
diarrhoea, fermentation, and others. These mechanisms might represent the primary bacterial processes related with intestine
function, revealing new information on shrimp and water ecology. Although the relative abundances in the bacterial composition
were different in shrimp intestine, water and sediment, the bacterial communities were almost similar, indicating the close
interaction between host and the environment in microbiome. Notably, the significant distribution of disease-related pathogens
including Vibrio and Flavobacterium in shrimp intestine and habitat water provided valuable information for disease prediction
and shrimp health management in the aquaculture industry. In summary, many common microbes and bacterial processes that
occur in the shrimp intestine and surrounding environment were revealed, and further functional analysis might help to modulate
these processes to promote shrimp development and health.
