Variations in microplastic pollution characteristics among different aquaculture modes: A case study from Dongting Lake area, China
A study of four aquaculture modes in China's Dongting Lake region found microplastics in all water and aquatic organism samples, with swamp eel ponds having the highest contamination and advanced ecological/facility systems showing notably lower levels. The findings are important for food safety because edible aquatic species across all farming methods were exposed to microplastics, with tailwater continuing to export contamination even from cleaner facilities.
Microbial Community in a Wastewater System
Researchers characterized microbial community composition in a wastewater treatment system, examining how treatment stage and operational conditions shape bacterial diversity and functional potential relevant to pollutant degradation.
Effectiveness assessment of using water environmental microHI to predict the health status of wild fish
Researchers tested whether measuring the health of microbial communities in river water could predict the health status of wild fish living there. The study found that the environmental microbiota health index was effective for bottom-dwelling fish but less reliable for fish living in the open water, suggesting this non-invasive monitoring approach works best for certain types of aquatic species.
The Extent and Pattern of Mariculture Impacts on Spatial and Seasonal Variations of Sediment Bacterial Communities Among Three Coastal Waters
Researchers used high-throughput sequencing to examine spatial and seasonal variations in sediment bacterial communities across three Chinese coastal bays with large-scale suspended mariculture, finding that spatial variation was a stronger driver of community composition than seasonality, with Proteobacteria, Bacteroidetes, and Planctomycetes dominating across all sites and mariculture-associated organic loading shaping local community structure.
Transferred Bacterial Community on the Potentially Pathogenic Bacteria among Aquatic Water, Plant Root, and Sediment When Planting with Chinese Herbs
This study used 16S rRNA sequencing to examine how traditional Chinese medicinal plants affect bacterial communities in aquaculture water, roots, and sediments. Understanding how plant-based treatments shift microbial ecology in fish farming environments informs sustainable aquaculture practices that reduce reliance on antibiotics linked to antibiotic resistance in the plastisphere.
Characteristics of microplastic pollution and analysis of colonized-microbiota in a freshwater aquaculture system.
Researchers found microplastics averaging 288.53 items per liter in freshwater aquaculture ponds in China, dominated by transparent fibers and cellulose particles, and discovered that bacterial communities on microplastic surfaces had significantly higher species richness and diversity than those in surrounding water. The plastisphere communities were enriched with Proteobacteria, including cellulose-degrading and potentially pathogenic species.
