“…In our study, large variations of AOA and AOB community abundance were found between different culture stages, which was consistent with previous studies in sediment (Nair et al . 2020). The AOB abundance was higher than AOA on Day 40, Day 50 and Day 60 in SCP sediments, and lower on Day 10, Day 20 and Day 30.…”

Aims Ammonia oxidation is a significant process of nitrogen cycles in a lot of ecosystems sediments while there are few studies in shrimp culture pond (SCP) sediments. This paper attempted to explore the community diversity and abundance of ammonia‐oxidizing archaea (AOA) and ammonia‐oxidizing bacteria (AOB) in SCP sediments at different culture stages. Methods and Results We collected SCP sediments and analysed the community diversity and abundance of AOA and bacteria in shrimp pond sediment at different culture stages using the ammonia monooxygenase (amoA) gene with quantitative PCR (qPCR) and 16S rRNA gene sequencing. The AOB‐amoA gene abundance was showed higher than AOA‐amoA gene abundance in SCP sediments on Day 50 and Day 60 after shrimp larvae introducing into the pond, and the diversity of AOA in SCP sediments was higher than that of AOB. The phylogenetic tree revealed that the most of AOA were the member of Nitrosopumilus and Nitrososphaera, and the majority of AOB sequences were clustered into Nitrosospira, Nitrosomonas clusters 6a and 7. The AOA community has close relationship with total organic carbon (TOC), pH, total phosphorus (TP), nitrate reductase, urease, acid phosphatase and β‐glucosidase. The AOB community was related to TOC, C/N and nitrate reductase. Conclusions AOA and AOB play the different ecological roles in SCP sediments at different culture stages. Significance and Impact of the Study Our results suggested that the different community diversity and abundance of AOA and AOB in SCP sediments, which may improve our ecological cognition of shrimp culture stages in SCP ecosystems.

“…(AOA), and Candidatus Kuenenia (anammox) were predominant in the bioaugmented pond. All the three groups of ammonia oxidizers co-existed in the system, with distinctly different mechanism of ammonia oxidation, substrate complementation, and metabolic interaction [71,72].

In the zero-water exchange shrimp culture pond maintained with the application of indigenous bioaugmentor, low levels of total ammonia–nitrogen were reported, indicating the relevance of indigenous microbial communities. Sediments (0–5 cm layer) were sampled from the pond (85th day) and the bacterial and archaeal communities; specifically, the ammonia oxidizers (ammonia-oxidizing bacteria, ammonia-oxidizing archaea, and anaerobic ammonia-oxidizing bacteria) in the sediment metagenome of the pond were analysed using the 16S rRNA and functional genes. Bacterial and archaeal 16S rRNA genes showed the relative abundance of Delta-Proteobacteria and Bacteroidetes groups performing sulphur respiration and organic matter degradation, archaeal groups of anaerobic sulphur respiring Crenarchaeotae, and chemolithoautotrophic ammonia oxidizers belonging to Thaumarchaeota. The presence of these diverse bacterial and archaeal communities denotes their significant roles in the cycling the carbon, nitrogen, and sulphur thereby bringing out efficient bioremediation in the bioaugmented zero-water exchange shrimp culture pond. Similarly, the functional gene-specific study showed the predominance of Nitrosomonas sp. (ammonia-oxidizing bacteria), Nitrosopumilus maritimus (ammonia-oxidizing archaea), and Candidatus Kuenenia (anaerobic ammonia-oxidizing bacteria) in the system, which points to their importance in the removal of accumulated ammonia. Thus, this study paves the way for understanding the microbial communities, specifically the ammonia oxidizers responsible for maintaining healthy and optimal environmental conditions in the bioaugmented zero-water exchange shrimp culture pond.

The aquaculture automation system (AcAS) is a user-friendly single-window unit. This allows end users to easily monitor and control the entire system through a built-in, customizable graphical user interface. AcAS was designed for simplicity, making it easy to con gure and use. This system was integrated with highly e cient industrial-grade environmental sensors (pH, conductivity, oxidation-reduction potential and dissolved oxygen) to ensure precise and error-free results in harsh environments. It can also store the user and system data in an attached memory device. It is equipped with built-in Wi-Fi, LoRa/ZigBee, and 4G/5G modules for data transfer, making it compatible with modern communication technology. It was programmed to be farmer-friendly and helped farmers maintain optimal shrimp growth conditions by monitoring various parameters. AcAS takes corrective measures as required, and provides updates to farmers through a graphical display unit. Additionally, farmers can con gure devices to receive alerts regarding important eld parameters or alarm conditions. Therefore, AcAS enhances the e ciency and sustainability of aquaculture farming by enabling precise control of farming conditions and proactive management of aquaculture.
