ClearCharacteristics 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.
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.
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.
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.
Connection between the Gut Microbiota of Largemouth Bass (Micropterus salmoides) and Microbiota of the aquaponics system Environment
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.
Underestimated Microplastic Pollution Derived from Fishery Activities and “Hidden” in Deep Sediment
Scientists measured microplastics in deep sediments of the Beibu Gulf (China) and found that fishing-related activities — particularly concentrated in historical fishing grounds — left distinct microplastic signatures at depth, revealing a hidden fishery-derived plastic legacy in seafloor sediments.
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.
Microbiome differences between wild and aquarium whitespotted eagle rays (Aetobatus narinari)
Researchers compared the gut microbiomes of whitespotted eagle rays living in aquariums versus the wild and found significant differences in bacterial communities, though aquarium rays appeared healthy, suggesting their microbiomes adapt to managed environments without causing obvious harm.
Assessing the bioaccumulation of microplastics in commercially important fish species
Researchers assessed microplastic accumulation in commercially important fish species from coastal and offshore waters, finding significant differences between species based on feeding strategies and habitat depth. Filter feeders and omnivorous species accumulated more microplastics than others, reflecting diet-based differences across trophic levels. The study raises concerns about human dietary exposure to microplastics through widely consumed seafood products.
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.
Impact of polypropylene microplastics and chemical pollutants on European sea bass (Dicentrarchus labrax) gut microbiota and health
Researchers investigated how polypropylene microplastics, alone and combined with chemical pollutants, affect the gut health and microbiome of European sea bass. They found that microplastic ingestion altered the gut microbial community composition and that combined exposure with pollutants amplified the harmful effects. The study suggests that microplastics may serve as carriers for toxic chemicals, compounding their impact on fish health and potentially affecting seafood safety.
The accumulation of microplastics in fish from an important fish farm and mariculture area, Haizhou Bay, China
Researchers investigated microplastic accumulation in six wild fish species from Haizhou Bay, a major fish farm and mariculture area in China, examining both digestive and non-digestive tissues. They found microplastics present in all fish species, with variation in abundance depending on species and tissue type. The findings raise concerns about microplastic transfer through aquaculture supply chains and potential implications for seafood safety.
Deciphering 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.
A multiple biomarker approach to understand the effects of microplastics on the health status of European seabass farmed in earthen ponds on the NE Atlantic coast
Researchers studied European seabass farmed in earthen ponds to understand how microplastic exposure relates to fish health. Using multiple biomarkers including blood chemistry, immune response, and tissue analysis, they found measurable biological changes linked to microplastic levels in the fish. The findings raise concerns about seafood quality from aquaculture systems that are exposed to environmental microplastic contamination.
Microplastic in the stomachs of open-ocean and deep-sea fishes of the North-East Atlantic
Researchers investigated microplastic occurrence in the stomachs of 390 fish from three pelagic and two deep-sea species in the North-East Atlantic, comparing plastic ingestion between fish occupying contrasting ocean compartments. The study documented microplastic presence across species at different depths, highlighting how plastic contamination extends throughout the oceanic water column.
Impaired Growth Performance of Wami Tilapia Juveniles (Oreochromis urolepis) (Norman, 1922) Due to Microplastic Induced Degeneration of the Small Intestine
Researchers characterized microplastic pollution in the deep-sea sediments of the South China Sea, detecting particles at all 11 sampling stations down to 3,000 m depth. Fiber density increased with water depth, suggesting settling of buoyant particles from surface waters over time.
Metagenomic Analysis of the Gastrointestinal Microbiota of Gadus morhua callarias L. Originating from a Chemical Munition Dump Site
Researchers used 16S rRNA metagenomic sequencing to compare gut microbiota of cod from a chemical munitions dump site in the Baltic Sea with those from a non-polluted reference site, finding significantly lower diversity and higher abundance of disease-associated bacterial taxa in dump-site fish. Probiotic taxa including Actinobacteriota were less prevalent in contaminated fish, suggesting chemical warfare agent contamination dysregulates the gut microbiome.
Occurrence of microplastics in epipelagic and mesopelagic fishes from Tuticorin, Southeast coast of India
Researchers investigated microplastic contamination in seawater and six fish species from different ocean depth habitats near Tuticorin, India. The study found microplastics in the gastrointestinal tracts of both epipelagic and mesopelagic fish, with contamination levels varying by species and habitat, suggesting that microplastic exposure extends across different marine depth zones and could affect human exposure through seafood consumption.
