ClearThe Characteristics of Intestinal Bacterial Community in Three Omnivorous Fishes and Their Interaction with Microbiota from Habitats
This study examined the gut bacterial communities of three omnivorous fish species in artificial fishery habitats, comparing them to bacteria in the surrounding water and sediment. Fish gut microbiomes partially reflected the environmental microbiota, suggesting habitat quality affects fish gut health. This is relevant to microplastics because microplastics alter both aquatic microbial communities and fish gut microbiomes.
Aquaculture Water Quality Improvement by Mixed Bacillus and Its Effects on Microbial Community Structure
This study tested two combinations of beneficial Bacillus bacteria in crucian carp aquaculture tanks, finding they improved water quality by reducing nitrogen and phosphorus compounds and shifted microbial community structure toward more beneficial species. Probiotic bacterial treatments offer a sustainable alternative to antibiotics for maintaining aquaculture water quality.
Culturomics and Amplicon-Based Metagenomic Insights into the Bacteria of Soils with High Yield of Oryza sativa L. subsp. Japonica
Researchers used culturomics and amplicon-based metagenomics to characterise bacterial communities in rhizosphere and bulk soils of high-yield Oryza sativa japonica paddy fields, identifying the microorganisms contributing to rice growth adaptability. The combined approach revealed the taxonomic composition and functional potential of the bacterial community in the paddy field agroecosystem.
Characteristics of microplastic pollution in golden pompano (Trachinotus ovatus) aquaculture areas and the relationship between colonized-microbiota on microplastics and intestinal microflora
Researchers found that microplastics in golden pompano aquaculture areas colonize with distinct microbial communities that overlap with the fish's gut microbiota, increasing Proteobacteria and decreasing Firmicutes in the intestinal flora of fish living in more contaminated estuarine settings.
Modern research on the study of the intestinal microbiome in fish (review)
This review examines recent research on the intestinal microbiome of fish, synthesizing findings on microbiome composition across more than 100 teleost species and exploring the microbiome as a potential biomarker for fish health and aquaculture optimization.
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.
Association of Fungi in the Intestine of Black Carp and Grass Carp Compared with their Cultured Water
Researchers characterized and compared the intestinal fungal communities of grass carp and black carp and their cultured water using high-throughput sequencing, finding species-specific differences in gut fungal composition that correlated partially with surrounding water microbiota.
Establishment of the Bacterial Microbiota in a Lab-Reared Model Teleost Fish, the Medaka Oryzias latipes
Researchers established a detailed characterization of the bacterial microbiota in lab-reared medaka (Oryzias latipes) across life stages from larvae to adults, addressing a significant knowledge gap in this important aquatic ecotoxicology model organism.
A fishy gut feeling – current knowledge on gut microbiota in teleosts
This review summarizes what scientists know about the community of bacteria living in fish guts and how diet, environmental conditions, and pollutants shape that community. Microplastics and other pollutants can disrupt the gut microbiome in fish, harming their immune function and overall health. Since fish are a major food source for humans, understanding these effects matters for food safety.
Dynamics of Gut Microbiome and Transcriptome in Korea Native Ricefish (Oryzias latipes) during Chronic Antibiotics Exposure
Researchers found that chronic low-dose exposure to erythromycin and ampicillin antibiotics disrupted the gut microbiome composition and altered immune and stress gene expression in Japanese rice fish (Oryzias latipes), suggesting that antibiotic residues in aquatic environments can cause lasting physiological effects in fish.
Application of intestinal microbiota in marine fish for assessing the toxicity of typical pollutants: a literature review
This review examines how the gut microbiota of marine fish can serve as biomarkers for assessing the toxic effects of ocean pollutants, including microplastics, heavy metals, antibiotics, and petroleum hydrocarbons. The study highlights that changes in key microbial communities in fish intestines reflect environmental contamination levels and could provide valuable indicators for monitoring marine ecosystem health.
Plastics in our water: Fish microbiomes at risk?
This review examined how microplastics and leached plasticizers affect the gut microbiomes of freshwater and marine fish, summarizing evidence for dysbiosis and reduced microbial diversity and discussing potential consequences for fish immunity, metabolism, and environmental fitness.
Effects of Rice–Frog Co-Cropping on the Soil Microbial Community Structure in Reclaimed Paddy Fields
This study tested whether raising frogs alongside rice in reclaimed farmland could improve soil health. Researchers found that rice-frog co-cropping significantly increased soil nutrients and microbial diversity compared to growing rice alone, suggesting this integrated farming approach could help restore the productivity of reclaimed agricultural land.
Within-species variation in the gut microbiome of medaka ( Oryzias latipes ) is driven by the interaction of light intensity and genetic background
This study found that gut microbiome composition in medaka fish is shaped by the interaction between genetic background and light intensity, with fishing-like selective pressure reducing bacterial richness under low-light conditions, though this did not affect growth rates.
Characterizing Microplastic Pollution and Microbial Community Status in Rice Paddy Soils Across Varied Environmental Settings in Songjiang, Shanghai: An Analysis of Morpho-Chemical Characteristics
Researchers characterized microplastic pollution and associated microbial communities in rice paddy soils, finding widespread microplastic contamination that correlated with shifts in soil bacterial diversity. Plastic-associated microbial communities differed from bulk soil communities, suggesting microplastics create distinct microbial niches in agricultural environments.
Microbiomes of the Aquatic Environment
This review examines the diversity and ecological roles of microbial communities in aquatic environments, covering microbiomes associated with aquatic insects, plants, fish, phytoplankton, macrophytes, and microplastics, and their interconnected functions in nutrient cycling and primary production. The authors discuss how climate change, eutrophication, and pollution are shifting microbial community composition in ways that threaten the functioning of freshwater and marine ecosystems.

Researchers investigated the relationship between gut microbiota composition in largemouth bass and the presence of microplastics in their digestive tracts, finding that microplastic-exposed fish showed distinct microbial community profiles. Certain bacterial taxa associated with plastic degradation were enriched in fish with higher microplastic burdens, suggesting gut microbiota adapt to plastic ingestion.
Potentially pathogenic bacteria in the plastisphere from water, sediments, and commercial fish in a tropical coastal lagoon: An assessment and management proposal
Researchers examined the types of potentially harmful bacteria living on microplastics found in water, sediments, and commercial fish in a tropical coastal lagoon. They identified several pathogenic species colonizing the microplastic surfaces, which could pose risks when contaminated fish are consumed by humans. The study proposes management strategies to reduce the public health threat of microplastic-associated pathogens in fisheries.
