ClearDeciphering the gut microbiome of grass carp through multi-omics approach
Researchers used multiple layers of molecular data (multi-omics) to map the gut microbiome of grass carp, identifying key bacterial functions and potential targets for improving fish gut health — findings that could benefit aquaculture and our understanding of how gut microbes support digestion in fish.
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.
A metagenomic analysis of gut microbiome phylogeny among four economically important carp species from wild and aquaculture farms
This publication presents a metagenomic analysis of gut microbiome phylogeny in four economically important carp species comparing wild and aquaculture populations, alongside research on the impact of different feed types on cannibalism in early larval stages of Koi carp.
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.
Novel Autochthonous Strains from Cyprinus carpio as Candidates for Probiotic Use and Microplastic-Degrading Properties
Researchers isolated six bacterial genera from the gut of common carp (Cyprinus carpio) and identified two novel Hafnia strains with both probiotic potential and microplastic-degrading properties, suggesting a dual role for gut bacteria in fish health and environmental bioremediation.
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.
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.
Impact of a chronic waterborne exposure to polystyrene nanoplastics on the gilthead seabream (Sparus aurata): Combining traditional and multi-omics approaches
Researchers exposed gilthead seabream to environmentally relevant and elevated polystyrene nanoplastic concentrations for 28 days, finding no visible tissue damage or blood abnormalities but significant shifts in gut microbiome diversity and dose-dependent changes in plasma metabolites linked to energy metabolism, suggesting subtle long-term risks for aquaculture production.
The effects of exposure to microplastics on grass carp (Ctenopharyngodon idella) at the physiological, biochemical, and transcriptomic levels
Researchers exposed grass carp to microplastics at two concentrations for 21 days and observed liver damage, inhibited growth, and increased oxidative stress. Transcriptome analysis revealed over 1,500 differentially expressed genes related to immune response, metabolism, and cellular stress pathways. The study suggests that microplastic exposure can trigger broad physiological and molecular disruptions in freshwater fish.
Gut microbiota of aquatic organisms: A key endpoint for ecotoxicological studies
This review examines how environmental contaminants including microplastics, pesticides, heavy metals, and pharmaceuticals affect the gut microbiota of aquatic organisms. Researchers highlight that changes in gut bacterial communities can serve as sensitive indicators of pollution exposure and may have downstream effects on host fitness. The study calls for improved methodologies to better link contaminant-induced shifts in gut microbiota to measurable health outcomes in aquatic species.
Effects of environmental factors on host-microbiota interactions in the guts of aquatic organisms: A review
This review synthesizes how environmental stressors — including microplastics, heavy metals, photoperiod, and aquaculture feed additives — alter gut microbiota in fish and aquatic invertebrates, identifying common patterns of microbial disruption and compromised gut barrier integrity.
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.
Metabarcoding Analyses of Gut Microbiota of Nile Tilapia (Oreochromis niloticus) from Lake Awassa and Lake Chamo, Ethiopia
Researchers used 16S rRNA metabarcoding to characterize the gut microbiota of Nile tilapia (Oreochromis niloticus) from Lakes Awassa and Chamo in Ethiopia, identifying 2,061 operational taxonomic units and comparing microbial community composition across gut regions and between luminal and mucosal sample types.
Isolations and Characterization of Novel Bacterial Species from Cyprinus Carpio and Its Use in Biodegradation of Polystyrene with Emphasis on SDG 3 for Ensuring Healthy Lives and Well-Being for All Humans and Animals
Novel bacterial species isolated from the gastrointestinal tract of common carp (Cyprinus carpio) were identified via 16S rRNA sequencing and tested for polystyrene biodegradation capability, with findings supporting the potential of gut microbiome bacteria as probiotics for plastic bioremediation.
Identification and Characterization of New Hafnia Strains from Common Carp (Cyprinus carpio), Potentially Possessing Probiotic Properties and Plastic Biodegradation Capabilities
Researchers isolated and characterized two novel Hafnia bacterial strains from the gut of common carp (Cyprinus carpio), identifying genes associated with both probiotic properties and microplastic degradation capabilities. Next-generation sequencing confirmed the strains carry ClpB heat shock protein and MP-degrading genes, presenting them as candidate organisms for simultaneous probiotic and bioremediation applications.

The 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.
