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.
Polystyrene nanoplastics sequester the toxicity mitigating potential of probiotics by altering gut microbiota in grass carp (Ctenopharyngodon idella)
Researchers tested whether probiotic pretreatment could protect grass carp from the toxic effects of polystyrene nanoplastics on gut health. While probiotics initially boosted immune responses and reduced intestinal damage, the protective effect was not strong enough to fully counteract nanoplastic toxicity over time. The study suggests that nanoplastics can undermine the gut health benefits of probiotics by disrupting the balance of gut bacteria.

Polystyrene microplastics were found to alter the gut microbiome of tilapia, disrupting the growth kinetics and metabolism of probiotic bacteria, with potential implications for fish health and aquaculture productivity.
Micro-bioplastic impact on gut microbiome, cephalic transcription and cognitive function in the aquatic invertebrate Daphnia magna
Researchers exposed water fleas (Daphnia magna) to bioplastic microparticles and studied the effects on their gut bacteria, brain gene activity, and behavior. They found that bioplastic exposure altered the gut microbiome and changed gene expression in the brain related to neural signaling, which correlated with reduced feeding and behavioral changes. The study suggests that even bioplastics, often considered more environmentally friendly, can disrupt the gut-brain connection in aquatic organisms.
Multi-mechanistic effects of bisphenol A on testicular dysfunction and endocrine disruption in adult male Labeo bata: oxidative stress, inflammation, and dysregulated energy sensors
Researchers studied how bisphenol A (BPA), a chemical that leaches from microplastics in water, affects reproductive function in male fish. They found that chronic BPA exposure at environmentally relevant concentrations caused significant testicular damage, including reduced sperm production, increased inflammation, and disrupted hormone signaling. The study reveals multiple mechanisms by which this common microplastic-associated chemical can impair male reproductive health in aquatic species.
Alteration of shoaling behavior and dysbiosis in the gut of medaka (Oryzias latipes) exposed to 2-μm polystyrene microplastics
Scientists exposed small freshwater fish (medaka) to fine polystyrene microplastics and found that the fish stopped schooling together -- a key social behavior -- during the exposure period, though the behavior recovered after exposure ended. The microplastics also disrupted the fish's gut bacteria, reducing beneficial species that produce short-chain fatty acids known to influence brain function through the gut-brain connection. This suggests microplastics may alter animal behavior by disrupting the gut microbiome.
Bisphenol A Induces Histopathological, Hematobiochemical Alterations, Oxidative Stress, and Genotoxicity in Common Carp (Cyprinus carpio L.)
Researchers investigated the toxic effects of bisphenol A, a plastics-related endocrine disruptor, on common carp at different dose levels over 30 days. The study found dose-dependent reductions in blood cell counts, increased oxidative stress in the brain, liver, gills, and kidneys, and significant tissue damage, indicating that BPA exposure poses risks to aquatic organisms.
Exposure to microplastics impairs fish's major behaviors. A novel threat to aquatic ecosystem
This review synthesises evidence on how microplastic exposure alters key behaviours in fish including feeding, reproduction, predator avoidance, and social interaction. It identifies neurological disruption, chemical co-toxicity, and gut effects as primary mechanisms, and highlights exposure to realistic environmental concentrations as an ongoing knowledge gap.
Multi-Species Probiotics as Sustainable Strategy to Alleviate Polyamide Microplastic-Induced Stress in Nile Tilapia
Researchers tested whether multi-species probiotics could counteract the toxic effects of polyamide microplastics in Nile tilapia over a six-week experiment. The study found that probiotic supplementation alleviated microplastic-induced stress by improving growth performance, immune response, and physiological health markers, suggesting that probiotics may be a sustainable strategy for protecting farmed fish from microplastic contamination.
Determination of Bisphenol Compounds and the Bioaccumulation after Co-Exposure with Polyethylene Microplastics in Zebrafish
Researchers developed a method to measure how bisphenol A and bisphenol S accumulate in zebrafish tissues when microplastics are also present. They found that microplastics increased the accumulation of these hormone-disrupting chemicals in fish tissues, with BPA building up more than BPS. The evidence indicates that microplastics can act as carriers that enhance the uptake of harmful chemicals by aquatic organisms.
Bisphenol A Used in Plastic Industry Negatively Affects Wild Vimba Bream (Vimba vimba)
Researchers found that long-term exposure of wild vimba bream to bisphenol A caused significant histopathological damage in liver and gill tissues and altered antioxidant enzyme activity, demonstrating the endocrine-disrupting chemical's harmful effects on freshwater fish.
Microplastic Exposure Across Trophic Levels: Effects on the Host Microbiota of Freshwater Organisms
Researchers investigated how microplastic exposure affects the gut bacteria communities of freshwater organisms including fish, invertebrates, and crustaceans. Microplastics—particularly when combined with pesticides—altered gut microbiota composition, which could impair digestion, immunity, and overall health of freshwater species.
Unraveling the mechanism of brain damage in Carassius auratus by polypropylene microplastics and oxytetracycline via the brain-gut-microbiota axis
Researchers investigated how polypropylene microplastics and the antibiotic oxytetracycline together affect the brain-gut-microbiota axis of goldfish at environmentally realistic levels. They found that microplastics acted as carriers for the antibiotic, leading to significantly higher accumulation in the brain and intestine, worsening inflammation and suppressing key neurotransmitter enzymes. The study suggests that co-exposure to microplastics and antibiotics can trigger nervous system disruption through the gut-brain connection.
Some Behavioural and Physiological Effects of Plastics (Polyethylene) on Fish
Researchers examined behavioral and physiological effects of polyethylene microplastics on fish, finding that plastic exposure disrupted endocrine function, altered behavior, and impaired normal development and reproduction.
Micro/nano-plastics cause neurobehavioral toxicity in discus fish (Symphysodon aequifasciatus): Insight from brain-gut-microbiota axis
Researchers exposed juvenile discus fish to microfibers and nanoplastics and found that both types caused neurobehavioral problems, but through different mechanisms involving the brain-gut-microbiota axis. Nanoplastics weakened swimming and predatory abilities, while microfibers reduced growth, and both disrupted gut microbial communities that influence brain function. The study provides the first evidence linking microplastic-induced gut microbiome changes to neurological effects in fish through the gut-brain connection.
Effects of the Antidepressant Amitriptyline on Juvenile Brown Trout and Their Modulation by Microplastics
Researchers exposed juvenile brown trout to the antidepressant amitriptyline with and without polystyrene microplastics and found that microplastics modulated the pharmaceutical's effects on fish behavior and physiology, highlighting the complexity of combined pharmaceutical-plastic pollution in aquatic ecosystems.
Long-term exposure to polyethylene microplastics and glyphosate interferes with the behavior, intestinal microbial homeostasis, and metabolites of the common carp (Cyprinus carpio L.)
Researchers exposed common carp to polyethylene microplastics and the herbicide glyphosate, both individually and combined, over 60 days to study effects on brain and gut health. The combination of both pollutants was more harmful than either alone, suppressing swimming behavior, damaging intestinal barriers, disrupting gut bacteria, and altering metabolism. The study suggests that microplastics and agricultural chemicals together may pose greater risks to fish health than previously recognized.
Potential of feed supplements on morphometric and gonad weight of fish exposed to microplastics
Researchers investigated whether probiotic supplements from lactic acid bacteria and Vitamin C could mitigate the effects of microplastic exposure on the morphometric measurements and gonad weight of tilapia, finding that feed supplementation supported recovery in fish exposed to microplastic-contaminated diets.
Eco-toxicological insights: modulating bisphenol A-induced hematological changes with flaxseed diets in food fish Labeo rohita
Researchers fed flaxseed-supplemented diets to rohu fish exposed to bisphenol A to evaluate whether the dietary intervention could reduce BPA-induced hematological toxicity. Flaxseed supplementation significantly mitigated BPA-associated reductions in red blood cell count and hemoglobin, suggesting dietary omega-3 fatty acids can partially protect fish blood parameters from plastic chemical exposure.
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.
Experimental evidence of physiological and behavioral effects of microplastic ingestion in Sparus aurata
Researchers fed juvenile gilthead sea bream diets enriched with virgin and weathered microplastics for 21 days and assessed physiological and behavioral effects. The study found that weathered microplastics caused greater cellular stress and antioxidant enzyme activation in liver and brain tissue, and that microplastic-exposed fish became significantly bolder during social interactions, suggesting both physiological and behavioral consequences of microplastic ingestion.
Combined effects of polystyrene micro-/nano-plastics and imidacloprid on Gut–Brain axis and neurotoxicity in juvenile Carassius auratus
Researchers exposed juvenile crucian carp to polystyrene micro- and nanoplastics combined with the pesticide imidacloprid and found distinct size-dependent toxicity patterns. Nanoplastics primarily targeted the brain, causing blood-brain barrier breakdown and neurotoxic effects linked to behavioral changes, while microplastics caused more severe intestinal damage, with gut microbiome analysis implicating the microbiota-gut-brain axis as a pathway for systemic toxicity.
