“…Thus, understanding the relationship between the intestinal microbiota of bivalves and their cultured environment is crucial in determining the formation of intestinal microbial community and the adaptation of microorganisms in the intestine of the host to the environment. Although the relationships of bacterial communities in bivalve intestine and its aquaculture environment have been considered (Asmani et al, 2016;Lokmer et al, 2016;Laroche et al, 2018;Sun et al, 2019;Musella et al, 2020), those of pearl oyster intestine and its aquaculture environment have not been discussed. Pearl oyster (Pinctada fucata martensii) is a well-known filter feeder worldwide due to its capability to produce high-quality pearls (Yang et al, 2019a;Zhang et al, 2021).…”

Environmental microbiota plays a vital role in the intestinal microbiota of aquatic organisms. However, data concerning the association between the intestinal microbiota of pearl oyster Pinctada fucata martensii and the surrounding seawater are limited. The existing bacterial communities in pearl oyster intestine and surrounding water from two sites (D and H, within Liusha Bay in Guangdong, China) were investigated using 16S rRNA-based sequencing to explore the relationship among the two. D located in the inner bay, and H located in the open sea area outside bay. Results revealed the richness and diversity of pearl oyster intestinal microbiota to be less than those of the surrounding water, with 38 phyla and 272 genera observed as a result of the classifiable sequence. The microbiota compositions in the intestine and the surrounding water were diversified at the phylum and genus levels, with the sequencing data being statistically significant. However, the functional prediction of microbiota emphasized the overall similarity in the functional profile of the surrounding seawater and intestinal microbiomes. This profile was associated with metabolism of cofactors and vitamin, carbohydrates metabolism, amino acids metabolism, metabolism of terpenoids, and polyketides, metabolism of other amino acids, lipids metabolism, and energy metabolism. Seven common operational taxonomic units (OTUs), which belonged to phyla Tenericutes, Cyanobacteria, and Planctomycetes, were noted in the intestines of pearl oysters from two different sites. These OTUs may be affiliates to the core microbiome of pearl oyster. Significantly different bacterial taxa in the intestines of pearl oysters from two different sites were found at the phylum and genus levels. This finding suggested that the bacterial communities in pearl oyster intestines may exhibit some plasticity to adapt to changes in the surrounding water-cultured environment. This study generally offers constructive discoveries associated with pearl oyster intestinal microbiota and provides guidance for sustainable aquaculture.

“…Not only community composition but also bacterial densities diverged between the replicate tanks, causing the larvae in replicate tanks to be exposed to different bacterial taxa at different bacterial loads. Given the well‐documented link between host and rearing water microbiomes (Zheng et al ., 2017; Sun et al ., 2019; Angthong et al ., 2020), this heterogeneity may have its implications for the reproducibility of cultivation performance. In fact, high mortality and low reproducibility between replicate cultivations are commonly observed in hatcheries (Vestrum et al ., 2018).…”

“…As compared to terrestrial agriculture, aquatic organisms exist in closer relationship with their surrounding microbiomes (De Schryver and Vadstein, 2014). Numerous molecular studies have found a link between the microbiome of the host and that of the rearing environment (Chen et al ., 2017; Zheng et al ., 2017; Sun et al ., 2019; Angthong et al ., 2020). The cultivated organisms recrute and enrich specific taxa from their environment (Bakke et al ., 2015; Yan et al ., 2016; Li et al ., 2017; Xiong et al ., 2019; Zhang et al ., 2019).…”

The development of effective management strategies to reduce the occurrence of diseases in aquaculture is hampered by the limited knowledge on the microbial ecology of these systems. In this study, the dynamics and dominant community assembly processes in the rearing water of Litopenaeus vannamei larviculture tanks were determined. Additionally, the contribution of peripheral microbiomes, such as those of live and dry feeds, to the rearing water microbiome were quantified. The community assembly in the hatchery rearing water over time was dominated by stochasticity, which explains the observed heterogeneity between replicate cultivations. The community undergoes two shifts that match with the dynamics of the algal abundances in the rearing water. Source tracking analysis revealed that 37% of all bacteria in the hatchery rearing water were introduced either by the live or dry feeds, or during water exchanges. The contribution of the microbiome from the algae was the largest, followed by that of the Artemia, the exchange water and the dry feeds. Our findings provide fundamental knowledge on the assembly processes and dynamics of rearing water microbiomes and illustrate the crucial role of these peripheral microbiomes in maintaining health-promoting rearing water microbiomes.
