ClearDietary Artemisia arborescens Supplementation Effects on Growth, Oxidative Status, and Immunity of Gilthead Seabream (Sparus aurata L.)
Researchers tested whether adding dried Artemisia arborescens plant material to fish feed could improve the health and immune response of gilthead seabream. They found that the plant supplement enhanced antioxidant capacity and boosted immune markers in the fish without negatively affecting growth. The study suggests that medicinal plant supplements in aquaculture feed could offer a sustainable alternative to antibiotics for maintaining fish health.

Curcumin Mitigates Microplastic-Induced Damage in Livestock and Poultry: Mechanistic Insights and Strategies for Sustainable Farming
This review examines how curcumin, a natural compound from turmeric, can protect livestock and poultry from microplastic-induced damage. The research shows that curcumin activates antioxidant defenses and reduces inflammation caused by microplastic exposure in animals, suggesting that natural dietary supplements may offer a strategy for mitigating some health effects of plastic contamination.
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.
Impact of polystyrene microplastic exposure on gilthead seabream (Sparus aurata Linnaeus, 1758): Differential inflammatory and immune response between anterior and posterior intestine
Researchers fed gilthead seabream polystyrene microplastics for 21 days and found they triggered inflammation and immune disruption in both sections of the intestine, with the rear portion more severely affected. The microplastics activated inflammatory signaling pathways and weakened the gut barrier by reducing tight junction proteins. The findings suggest microplastic ingestion could compromise gut health and immune function in fish.
Microplastic ingestion in reared aquaculture fish: Biological responses to low-density polyethylene controlled diets in Sparus aurata
Researchers fed gilthead seabream fish diets enriched with virgin and weathered polyethylene microplastics for three months, followed by one month of clean feeding. Microplastic ingestion increased over time, with weathered particles accumulating more, but all particles were fully cleared from the digestive tract after the detoxification period. The study found no long-term effects on fish growth or body condition, suggesting that this species does not retain ingested microplastics in its digestive system over time.
Nanoplastics impair the intestinal health of the juvenile large yellow croaker Larimichthys crocea
Researchers exposed juvenile large yellow croaker fish to nano-sized polystyrene particles to assess impacts on intestinal health and growth. The study found that nanoplastics accumulated in the fish and caused disorders in digestion, antioxidant defenses, immune function, and intestinal microflora, indicating that nanoplastics can significantly impair gut health in commercially important marine fish species.
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.
Effect of Probiotic Supplimentations on the Gut Histoarchitecture of Stinging Catfish, Heteropneustes fossilis
This aquaculture study evaluated the effects of probiotic supplementation on gut histology in stinging catfish, finding that probiotics improved intestinal morphology—relevant to understanding how gut health modifications may influence susceptibility to microplastic-induced gastrointestinal damage.
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.
Natural-based solutions to mitigate dietary microplastics side effects in fish
Zebrafish reared for 6 months on diets containing microencapsulated astaxanthin and microplastics showed reduced oxidative stress and lower MP accumulation in liver compared to controls, suggesting antioxidant supplementation can mitigate the toxicological effects of dietary microplastic exposure.
Long-term exposure to microplastics induces oxidative stress and a pro-inflammatory response in the gut of Sparus aurata Linnaeus, 1758
Researchers fed gilthead seabream a diet containing low-density polyethylene microplastics for 90 days and found progressive increases in oxidative stress biomarkers, inflammatory enzyme activity, and tissue damage in the gut. After a 30-day depuration period, most biomarker values returned toward normal levels, indicating some recovery capacity. The study demonstrates that long-term microplastic ingestion can induce sustained oxidative stress and inflammation in fish intestines.
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.
Micro-algal astaxanthin ameliorates polystyrene microplastics-triggered necroptosis and inflammation by mediating mitochondrial Ca2+ homeostasis in carp’s head kidney lymphocytes (Cyprinus carpio L.)
Researchers investigated whether astaxanthin, a natural pigment from microalgae, could protect carp immune cells from damage caused by polystyrene microplastics. They found that astaxanthin reduced inflammation and cell death triggered by microplastics by helping maintain calcium balance within the cells' mitochondria. The study suggests that natural antioxidant compounds may help mitigate some of the harmful immune effects of microplastic exposure in fish.
Effect of dietary cinnamon supplementation on the growth in length, haematology, serum biochemistry, intestinal microbiota and enzymes and histomorphological changes of the intestine, liver and the kidney of Heteroclarias (Clarias gariepinus ♀ × Heterobra ♂)
Dietary cinnamon supplementation at 1-2% significantly improved growth, blood parameters, antioxidant enzyme activity, and intestinal health in juvenile catfish over a 56-day trial. The spice enhanced beneficial gut microbiota while reducing pathogenic bacteria, suggesting cinnamon as a natural feed additive for aquaculture.
