Litopenaeus vannamei gut and aquaculture water metagenome
The greenhouse shrimp farming model represents an emerging, intensive aquaculture system in China, characterized by high-density farming, controlled environmental conditions, and efficient resource utilization, aimed at achieving high yield and productivity. This model has been widely adopted in many coastal regions. Specifically, shrimp intestine and aquaculture water samples were collected from Jiangsu (n = 25), Guangdong (n = 25), Guangxi (n = 20), and Fujian (n = 20). The selected systems were randomly sampled from hundreds of independent greenhouses maintained by local shrimp farmers to ensure representative coverage. All sampled shrimp were healthy, active, and in good physiological condition at the time of collection, which occurred uniformly in September, shortly before harvest.
