ClearEffectiveness 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 Structure and Function of Gut Microbiomes of Two Species of Sea Urchins, Mesocentrotus nudus and Strongylocentrotus intermedius, in Japan
This study characterized the gut microbiomes of two sea urchin species important to Japanese marine aquaculture using metagenomic methods, revealing distinct microbial communities linked to habitat and growth conditions. Understanding the microbiome of aquaculture organisms is relevant to their health and food safety, particularly given that environmental contaminants including microplastics can alter gut microbiota.
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.
Variation in the gut microbiota of wild Eurasian otter (Lutra lutra) likely reflects diet shifts between snow-free and snow seasons
Researchers studied the gut bacteria of wild Eurasian otters across two seasons, finding that their microbiome shifts significantly depending on what they eat — fish in summer versus high-fat prey in winter. The study notes that future comparisons with urban otters could reveal whether microplastic contamination in waterways disrupts their gut health.
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.
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 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.
Characterization of skin- and intestine microbial communities in migrating high Arctic lake whitefish and cisco
Researchers characterized the skin and intestinal microbiomes of migratory Arctic lake whitefish and cisco, finding that microbial communities varied between species and body sites, with implications for understanding fish health in changing Arctic environments.
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.
Diet shapes cold‐water corals bacterial communities
Researchers found that diet significantly shapes the bacterial communities living in cold-water corals, with carnivorous and herbivorous diets producing distinct microbiomes. The study sheds light on the ecological factors driving microbial diversity in deep-sea coral ecosystems.
Influence of host phylogeny and water physicochemistry on microbial assemblages of the fish skin microbiome
Researchers conducted a large-scale analysis of nearly 2,000 fish skin microbiome samples across 98 species to understand what factors shape microbial communities on fish surfaces. They found that host evolutionary history and water chemistry, particularly salinity and temperature, were the strongest predictors of skin microbiome composition. The study provides a broad framework for understanding how environmental stressors, including pollutants, may disrupt the beneficial microbial communities on fish.
Differences in Physiological Performance and Gut Microbiota between Deep-Sea and Coastal Aquaculture of Thachinotus Ovatus: A Metagenomic Approach
Researchers compared the physiological performance and gut microbiota of pompano fish raised in deep-sea versus coastal aquaculture environments in China's Beibu Gulf. They found that deep-sea farming produced better growth performance, stronger immune responses, and more diverse intestinal microbial communities. The study suggests that deep-sea aquaculture environments, with lower pollution levels including fewer microplastics, may offer significant advantages for fish health and production quality.
The interplay between host-specificity and habitat-filtering influences sea cucumber microbiota across an environmental gradient of pollution
Researchers studied how pollution levels along a Hong Kong coastline affect the gut and skin microbiomes — communities of bacteria living on and in organisms — of a tropical sea cucumber, finding that the animal maintains its own distinct microbial community even in highly polluted areas. This suggests sea cucumbers have strong internal mechanisms that shape their microbiome independently of the surrounding environment, which may help them survive in contaminated coastal waters.
Differences in gut microbial diversity and composition between growth phenotypes of farmed juvenile sandfish, Holothuria scabra
Researchers analyzed the gut bacteria of farmed sandfish sea cucumbers to understand why individuals from the same batch grow at different rates. They found that fast-growing and slow-growing animals had distinct gut microbial communities with different predicted metabolic functions. The study also cautioned that fecal samples do not accurately represent the gut microbiome, which is important for future aquaculture research methods.
Within-species variation in the gut microbiome of medaka (Oryzias latipes) is driven by the interaction of light intensity and genetic background
This paper is not about microplastics; it studies how light intensity and evolutionary history (lineages selected under fishing-like vs. natural mortality) interact to shape gut microbiome diversity and composition in medaka fish.
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.
Variations and Interseasonal Changes in the Gut Microbial Communities of Seven Wild Fish Species in a Natural Lake with Limited Water Exchange during the Closed Fishing Season
Researchers analyzed the gut bacteria of seven wild fish species in Chaohu Lake, China, across all four seasons and found significant differences in microbial communities between species and across seasons. Environmental factors like water temperature and dissolved oxygen levels were key drivers of these microbial shifts. The study provides a baseline understanding of how natural conditions shape the gut health of wild freshwater fish populations.
Blood and cloacal microbiome profile of captive green turtles (Chelonia mydas) and hawksbill turtles (Eretmochelys imbricata): Water quality and conservation implications
Researchers analyzed the gut and blood microbiomes of captive green and hawksbill sea turtles and found that environmental factors — including microplastic polymer exposure and heavy metals — significantly shaped microbial community composition and correlated with blood health markers, underscoring the role of water quality in sea turtle conservation.
The interplay between host-specificity and habitat-filtering influences sea cucumber microbiota across an environmental gradient of pollution
Researchers examined how environmental pollution gradients influence intra-specific variation in microbiota diversity and structure across skin, gut, sediment, and water communities associated with sea cucumbers. They found that both host-specificity and habitat-filtering interact to shape microbial communities along pollution gradients, with animal-associated microbiota showing distinct patterns compared to environmental communities.
Consumer feces impact coral health in guild-specific ways
Researchers tested the effect of fresh and heat-killed feces from corallivorous and grazer/detritivorous fish on coral health, finding that fresh grazer/detritivore feces caused detrimental effects while corallivore feces did not, implicating live microbiota in grazer feces as the harmful agent. The study revealed that consumer microbiota can impact coral health in guild-specific ways, with bacterial diversity varying across ten fish species reflecting their ecological roles.
Microbiome Composition and Function in Aquatic Vertebrates: Small Organisms Making Big Impacts on Aquatic Animal Health
This review examines how microbiomes (communities of microorganisms) function in fish and marine mammals, and how environmental stressors like microplastics can disrupt them. Microplastics in water can alter the natural balance of beneficial microbes in aquatic animals, potentially affecting their health and the safety of seafood. Understanding these disruptions matters because changes in fish microbiomes could affect the quality and safety of the fish that end up on our plates.

Multi-omics association pattern between gut microbiota and host metabolism of a filter-feeding fish in situ exposed to microplastics
Scientists exposed filter-feeding fish to environmentally realistic levels of microplastics and found that the particles reshaped gut bacteria communities, which in turn altered the fish's liver metabolism through changes in amino acid processing. This gut-microbiome-to-organ connection matters because it shows microplastics may affect human health not just through direct toxicity but by disrupting the beneficial bacteria in our digestive systems.
