Researchers found that supplementing tilapia feed with probiotics or vitamin C significantly mitigated microplastic-induced organ damage, reducing liver necrosis and inflammation markers while improving intestinal structure and immune cytokine balance.
Assessing the recovery of steroid levels and gonadal histopathology of tilapia exposed to polystyrene particle pollution by supplementary feed
Researchers investigated whether supplementary feed containing probiotics and vitamin C could mitigate the reproductive harm caused by polystyrene particle exposure in tilapia, assessing steroid levels and gonadal histopathology after exposure. Results indicated that plastic particle pollution negatively affected tilapia reproduction and that probiotic and vitamin C supplementation offers a potential dietary strategy to counter these effects.
Effect of microplastic particles on the gills structure of freshwater fish supplemented with probiotics and vitamin C
This study tested whether commercial feed supplemented with probiotics and vitamin C could repair gill tissue damage in Nile tilapia (Oreochromis niloticus) caused by microplastic particle exposure. Both supplements showed protective effects on gill histology, suggesting dietary interventions may partially mitigate microplastic-induced tissue damage in farmed fish.
The Effects of Probiotics on the Recovery of Growth, Digestive, Antioxidant, Immune Functions, and Gut Microbiota of Chinese Hooksnout Carp (Opsariichthys bidens) Under Microplastic Stress
Researchers exposed juvenile Chinese hooksnout carp to polystyrene microplastics for seven days, then administered Bacillus coagulans probiotics at three doses for 56 days and found that medium and high probiotic doses significantly improved growth, digestive enzyme activity, antioxidant function, and gut microbiota recovery.
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.
Probiotics ameliorate polyethylene microplastics-induced liver injury by inhibition of oxidative stress in Nile tilapia (Oreochromis niloticus)
Researchers investigated whether probiotics could protect Nile tilapia from liver damage caused by polystyrene microplastics. The study found that fish pre-fed with probiotics showed significantly reduced oxidative stress markers in the liver compared to those exposed to microplastics alone, suggesting that probiotics may help mitigate microplastic-induced hepatic oxidative damage in fish.
Polystyrene microplastics interaction and influence on the growth kinetics and metabolism of tilapia gut probiotic Bacillus tropicus ACS1
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.
Microplastics induced endocrine disruption, alteration in testicular tissue in tilapia (Oreochromis niloticus) pre-fed on Amphora coffeaeformis
Researchers found that microplastic exposure caused hormonal disruption, reduced sperm quality, and damaged testicular tissue in male tilapia fish, but pre-feeding the fish with a microalgae feed supplement partially protected against these reproductive harms. The study suggests that dietary interventions may help mitigate microplastic toxicity in fish farmed for human consumption.
Impacts of microplastics on reproductive performance of male tilapia (Oreochromis niloticus) pre-fed on Amphora coffeaeformis
Researchers found that microplastics caused significant blood, biochemical, and reproductive harm in male Nile tilapia, including reduced testosterone and testicular damage. However, pre-feeding fish with the diatom Amphora coffeaeformis helped protect against many of these negative effects, suggesting certain dietary supplements may help organisms cope with microplastic exposure.
Toxicological assessment of dietary exposure of polyethylene microplastics on growth, nutrient digestibility, carcass and gut histology of Nile Tilapia (Oreochromis niloticus) fingerlings
Researchers fed Nile tilapia fish diets containing different amounts of polyethylene microplastics and found that higher levels significantly reduced growth, nutrient absorption, and body composition. Fish exposed to the highest microplastic concentration (10%) showed severe gut damage visible under a microscope. Since tilapia is widely farmed for human consumption, these findings raise concerns about microplastic contamination affecting both fish health and the safety of farmed seafood.
Correlation of Water Quality with Microplastic Exposure Prevalence in Tilapia (Oreochromis niloticus)
Researchers exposed tilapia to polyethylene microplastics at three concentrations and assessed effects on water quality and microplastic accumulation in gastrointestinal, liver, gill, and gonad tissues, finding that higher concentrations were associated with elevated microplastic prevalence and tissue-specific accumulation patterns.
Chlorella alleviates the intestinal damage of tilapia caused by microplastics
Researchers investigated how polyethylene microplastics of different sizes affect the intestinal health of tilapia and whether Chlorella algae supplementation could alleviate the damage. They found that microplastics caused intestinal histological changes and disrupted enzyme activities, gene expression, and gut microbiota in the fish. The addition of Chlorella showed potential to mitigate some of the intestinal damage caused by nanoscale microplastic exposure.
Effects of Virgin Microplastics on Growth, Intestinal Morphology and Microbiota on Largemouth Bass (Micropterus salmoides)
Researchers found that exposure to virgin microplastics at environmentally relevant concentrations impaired growth, caused intestinal morphological damage, and altered gut microbiota composition in largemouth bass, suggesting that microplastic ingestion poses health risks in commercially important aquaculture species.
Spirulina platensis supplementation remediates microplastics-induced growth inhibition and stress in Nile tilapia, Oreochromis niloticus
Nile tilapia fish exposed to microplastics showed reduced growth, intestinal damage, and signs of immune stress, but adding the dietary supplement Spirulina to their feed significantly reversed these harmful effects. Spirulina reduced oxidative stress and helped repair gut damage caused by microplastic exposure. While this is a fish study, it suggests that certain natural supplements might help protect against some of the biological damage caused by microplastic ingestion.
Histomorphological Changes in Fish Gut in Response to Prebiotics and Probiotics Treatment to Improve Their Health Status: A Review
This review summarizes how prebiotics and probiotics, beneficial supplements added to fish feed, can improve gut health and disease resistance in farmed fish. A healthy gut microbiome is critical for nutrient absorption and immune defense in fish. While not directly about microplastics, the research is relevant because microplastics are known to disrupt gut bacteria in aquatic organisms, and probiotics may help counteract some of those effects.
Advances in Understanding Micro‐ and Nanoplastic Toxicity on Farmed Fish and Emerging Nutritional Interventions
This review examined the toxic effects of micro- and nanoplastics on farmed fish and explored emerging nutritional interventions to mitigate those effects. Researchers found that microplastics reduce feed utilization, cause physical abrasion, and trigger oxidative stress in fish, while certain dietary supplements show promise in enhancing fish resilience against microplastic-related toxicity.
Microplastics in aquaculture - Potential impacts on inflammatory processes in Nile tilapia
Researchers fed Nile tilapia a diet containing a mixture of four common microplastics and found that the particles triggered inflammatory responses in both adult and juvenile fish. The microplastics activated immune pathways and caused tissue changes in the gut and other organs, with juveniles being more sensitive. Since tilapia is one of the most widely farmed fish in the world, these findings raise concerns about the safety of farm-raised fish exposed to microplastic-contaminated water.
Comprehensive understanding the impacts of dietary exposure to polyethylene microplastics on genetically improved farmed tilapia (Oreochromis niloticus): tracking from growth, microbiota, metabolism to gene expressions
Researchers investigated the impacts of dietary polyethylene microplastics on genetically improved farmed tilapia over nine weeks, tracking effects on growth, gut microbiota, liver metabolism, and gene expression. The study found that microplastic exposure altered gut microbial communities, disrupted liver metabolic processes, and affected gene expression in brain and liver tissues. The findings suggest that microplastic contamination in fish feed and aquatic environments poses risks to farmed fish health.
Arachidonic acid reverses microplastic-induced macrophage dysfunction in teleost fish
Researchers found that polystyrene microplastics impaired macrophage immune function in Nile tilapia, increasing susceptibility to Streptococcus infection; supplementing fish with arachidonic acid reversed this dysfunction by restoring macrophage metabolic activity. The findings suggest that dietary fatty acid supplementation could protect fish immune systems in aquaculture operations exposed to microplastic contamination.
