Impacts of polyethylene microplastics on the microalga, Spirulina (Arthrospira platensis)
This study examined how polyethylene microplastics affect Spirulina, a widely cultivated blue-green algae used in food and supplements. Researchers found that at higher concentrations, microplastics reduced Spirulina growth and caused oxidative stress, while the algae also physically entangled with the plastic particles. The findings suggest that microplastic contamination could threaten both natural algal ecosystems and the commercial production of this important food source.
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.
Spotlight on the long-term effects of micro/nanoplastics exposure on Spirulina platensis: Algal cells, extracellular polymeric substances, and phycocyanin
Scientists studied the effects of micro and nanoplastics on Spirulina, a nutritional algae widely used as a food supplement, over a 50-day period. The plastic particles slowed Spirulina growth, damaged cell surfaces, and initially reduced the quality and quantity of phycocyanin, a valuable blue pigment. Since Spirulina is consumed by humans as a health food, microplastic contamination in algae culture environments could affect the quality and safety of these supplements.
Natural-based solutions to mitigate dietary microplastics side effects in fish

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.
Mitigation of Dietary Microplastic Accumulation and Oxidative Stress Response in Rainbow Trout (Oncorhynchus mykiss) Fry Through Dietary Supplementation of a Natural Microencapsulated Antioxidant
Researchers tested whether a microencapsulated natural antioxidant, astaxanthin, could protect rainbow trout fry from the harmful effects of dietary microplastics over a 60-day feeding trial. The antioxidant supplement reduced microplastic accumulation in fish tissues and helped counteract oxidative stress caused by the plastic particles. The findings suggest that dietary interventions could help mitigate microplastic harm in farmed fish, with potential implications for aquaculture safety.
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.
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.
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.
Growth performance, hematological and oxidative stress responses in Nile tilapia (Oreochromis niloticus) exposed to polypropylene microplastics
Nile tilapia fish fed polypropylene microplastics for 7 weeks showed significantly reduced growth, blood abnormalities indicating anemia, and oxidative stress damage in both liver and brain tissue. The effects were dose-dependent, with higher microplastic concentrations causing more severe harm. Since tilapia is one of the most widely farmed and consumed fish globally, these findings raise concerns about the health of both farmed fish and the people who eat them.
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.
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.
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

Mitigating Dietary Microplastic Accumulation and Oxidative Stress Response in European Seabass (Dicentrarchus labrax) Juveniles Using a Natural Microencapsulated Antioxidant
In a study with European seabass, researchers found that microplastics in fish feed were absorbed through the gut and accumulated in the liver, triggering oxidative stress. However, when the fish were also given microencapsulated natural astaxanthin (an antioxidant), it reduced both the stress response and the amount of microplastics absorbed by clumping the particles together in the gut. This suggests that certain natural compounds might help reduce the harmful effects of dietary microplastic exposure.
The impact of polystyrene nanoplastics (PSNPs) on physiological and biochemical parameters of the microalgae Spirulina platensis
Researchers exposed the microalgae Spirulina platensis to polystyrene nanoplastics at three concentrations over 20 days and found dose-dependent reductions in growth rate, dry weight, and photosynthetic pigments alongside increased oxidative stress markers, indicating nanoplastics impair algal physiology even at relatively low exposure levels.
