ClearInduction of detoxification systems in wild red mullet Mullus surmuletus after microplastic ingestion
Wild red mullet caught near Mallorca were found to have ingested microplastics in 28% of sampled fish, and those fish showed activation of liver detoxification systems compared to fish without plastic in their stomachs. This is among the first evidence that wild fish experience physiological responses to microplastic ingestion, though no oxidative damage was detected.
A Biomarker Approach as Responses of Bioindicator Commercial Fish Species to Microplastic Ingestion: Assessing Tissue and Biochemical Relationships
Researchers assessed microplastic intake and antioxidant biomarker responses in three Mediterranean fish species, finding that microplastic ingestion correlated with oxidative stress indicators across red mullet, bogue, and anchovy populations.
Microplastic-induced oxidative stress response in turbot and potential intake by humans
Researchers examined microplastic contamination in turbot tissues and assessed the oxidative stress response caused by ingested particles. They found that microplastics accumulated most heavily in the gills and caused significant oxidative damage, particularly in the liver. The study also estimated human microplastic intake through fish consumption, highlighting a potential pathway for dietary exposure.
Microplastics’ Occurrence in Edible Fish Species (Mullus barbatus and M. surmuletus) from an Italian Marine Protected Area
Researchers assessed microplastic contamination in the gastrointestinal tracts and livers of red mullet species (Mullus barbatus and M. surmuletus) from a Marine Protected Area in the Ionian Sea, finding microplastics in over 60% of specimens at an average of three items per fish. ATR-FTIR and pyrolysis-GC/MS identified the dominant polymer types, with red mullets showing nearly twice the contamination levels of striped red mullets.
First evidence of in vitro cytotoxic effects of marine microlitter on Merluccius merluccius and Mullus barbatus, two Mediterranean commercial fish species
This study exposed primary cell cultures from Mediterranean commercial fish — European hake and red mullet — to real marine microlitter collected from coastal waters, finding cytotoxic effects in immune and mucosal tissues. Importantly, both fish species had ingested plastics including HDPE and polypropylene, providing evidence that environmental (not just laboratory) microplastic contamination harms marine food fish.
Microplastics accumulation in gastrointestinal tracts of Mullus barbatus and Merluccius merluccius is associated with increased cytokine production and signaling
Researchers found microplastics in the gastrointestinal tracts of red mullet and European hake from the Mediterranean and showed that MP accumulation was associated with elevated production of pro-inflammatory cytokines in gut tissue. The immunotoxic response to ingested MPs suggests that plastic contamination may chronically impair immune function in commercially important fish species.
Effects of anthropogenic and environmental stressors on the current status of red mullet (Mullus barbatus L., 1758) populations inhabiting the Bulgarian Black Sea waters
Researchers assessed the health of red mullet populations in the Bulgarian Black Sea, finding that fish from the southern region ingested more microplastics and showed elevated oxidative stress and reduced antioxidant defenses. The study suggests these populations are under significant anthropogenic pressure, with genetic markers indicating patterns typical of overexploited species.
Assessment of the impact of microplastic ingestion in striped red mullets from an Eastern Mediterranean coastal area (Zakynthos Island, Ionian Sea)
Researchers examined microplastic ingestion in striped red mullet fish from the coast of Zakynthos, Greece, finding fewer microplastics in fish from the marine protected area compared to tourist-heavy coastal sites. However, the overall number of ingested microplastics was low, and no clear link was found between microplastic ingestion and biological damage markers or chemical contamination in the fish. This suggests that at current contamination levels in this area, microplastics may not yet be causing measurable harm to these fish.
Presence and Potential Effect of Microplastics Associated with Anthropic Activity in Two Benthic Fishes Serranus scriba and Lithognathus mormyrus
Researchers compared microplastic ingestion and oxidative stress responses in two Mediterranean coastal fish species (Serranus scriba and Lithognathus mormyrus) from sites with different levels of human activity near Mallorca, finding higher microplastic loads and greater antioxidant enzyme activity at the more impacted site.
Microplastic Presence in the Digestive Tract of Pearly Razorfish Xyrichtys novacula Causes Oxidative Stress in Liver Tissue
Microplastics were found in 89% of pearly razorfish (Xyrichtys novacula) specimens from the Balearic Islands, with fish carrying more than 4 MPs showing elevated activities of glutathione peroxidase, glutathione reductase, and glutathione S-transferase in liver tissue, indicating oxidative stress and detoxification responses.
Abundance and Characteristics of Fibrous Microplastics and Microfibers Isolated in Mullus barbatus from the Adriatic Sea—Preliminary Investigation
This preliminary study assessed the occurrence of fibrous microplastics and microfibers in red mullet (Mullus barbatus) from the Adriatic Sea, finding contamination across sampled fish. The results provide baseline data on microfiber ingestion in a commercially important Mediterranean fish species.
Are anthropogenic fibres a real problem for red mullets (Mullus barbatus) from the NW Mediterranean?
Analysis of anthropogenic fibers in red mullets from the northwest Mediterranean Sea found that fibers were present in 50% of fish, with cellulose-based fibers more common than synthetic polymers, and ingestion increased significantly between 2007 and 2018. No histopathological damage or health effects were associated with fiber ingestion at current contamination levels.
Antioxidants and molecular damage in Nile Tilapia (Oreochromis niloticus) after exposure to microplastics
Researchers exposed juvenile Nile Tilapia to different concentrations of microplastics for 15 days followed by a recovery period. The study found dose-dependent increases in oxidative stress markers, DNA fragmentation, and altered protein patterns in fish exposed to microplastics. Evidence indicates that while fish exposed to the lowest concentration recovered after the treatment ended, higher doses caused more persistent damage.
Microplastics in wild fish from North East Atlantic Ocean and its potential for causing neurotoxic effects, lipid oxidative damage, and human health risks associated with ingestion exposure
Researchers examined microplastic contamination in three commercially important fish species from the North East Atlantic Ocean and found that 49% of the 150 fish analyzed contained microplastics. Fish with microplastics showed significantly higher levels of lipid damage in the brain, gills, and muscle, along with signs of neurotoxicity. Based on the microplastics found in edible fish muscle, the study estimates that human consumers may ingest hundreds of microplastic particles per year from fish consumption alone.
Exposure to polypropylene microplastics via diet and water induces oxidative stress in Cyprinus carpio
Researchers fed carp fish polypropylene microplastics through both food and water and found that exposure caused oxidative stress in the liver, gills, and intestines. The damage was dose-dependent, with higher microplastic concentrations causing more harm to the fish's antioxidant defense systems. Since carp is a widely consumed fish, these findings raise questions about whether microplastics in aquaculture could affect the safety of fish as human food.
Deleterious Effects of Polypropylene Microplastic Ingestion in Nile Tilapia (Oreochromis niloticus)
Researchers fed Nile tilapia daily doses of polypropylene microplastics for 30 days and observed significant health effects including changes in blood cell counts, altered gut bacteria, and tissue damage to the intestines and liver. The higher dose group showed more pronounced effects, including elevated inflammatory markers and signs of oxidative stress. The study provides evidence that chronic ingestion of microplastics commonly found in aquatic environments can cause meaningful harm to a widely consumed fish species.
First evidence of in vitro cytotoxic effects of marine microlitter on Merluccius merluccius and Mullus barbatus , two Mediterranean commercial fish species
Researchers collected actual marine litter (not lab-made microplastics) from the Northern Adriatic Sea and tested its toxicity on cells from two commercially caught fish species. Real marine microlitter caused significant cell damage and inflammation, including effects not seen with pristine lab-grade microplastics. This suggests that studies using only clean, standardized plastic particles may underestimate the true toxicity of environmental microplastics.
Physiological Responses to Microplastic Ingestion in the Peacock Wrasse Symphodus tinca from Ibiza, Spain
Researchers assessed microplastic occurrence and physiological stress responses in peacock wrasse (Symphodus tinca) from the Balearic Islands, finding MPs in 60.7% of fish sampled with 58 total items. Fish with microplastics showed elevated markers of oxidative stress and detoxification enzyme activity compared to those without.
Oxidative Stress Induced by Exposure of Microplastics in Labeo Rohita
Exposure to low-density polyethylene (LDPE) microplastics caused dose-dependent oxidative stress in rohu fish (Labeo rohita) over 45 days. The findings suggest that microplastic contamination in aquatic environments can harm fish health through increased free radical damage.
Chronic LDPE microplastic ingestion: oxidative stress and mutagenicity in reef fish Stegastes fuscus
Researchers fed reef damselfish a diet containing low-density polyethylene microplastics for four months and observed increased DNA damage in blood cells and elevated oxidative stress markers in the brain. While the fish showed no changes in behavior, the cellular-level damage points to real biological harm from chronic microplastic ingestion. The findings highlight a hidden threat to reef fish health that could have cascading effects on coral reef ecosystems.
