ClearMicroplastic pollution: An emerging contaminant in aquaculture
This review examines how microplastics are contaminating aquaculture (fish farming) through wastewater, aging equipment, and fish feed, and harming cultured fish through oxidative stress, immune damage, and reproductive problems. Since aquaculture provides a major source of dietary protein worldwide, microplastic contamination in farmed fish is a direct food safety concern. The review recommends better water screening, facility maintenance, and feed quality control to reduce microplastic levels in fish farming.

The study also highlights mitigation strategies such as reducing single-use plastics, recycling, and using bioplastics.
Effects of microplastics, pesticides and nano-materials on fish health, oxidative stress and antioxidant defense mechanism
This review examines how microplastics, pesticides, and nanoparticles harm fish by causing oxidative stress, DNA damage, immune system disruption, and changes in gut bacteria. Since contaminated fish is a major pathway for microplastics and pesticides to enter the human diet, declining fish health and quality directly affect food safety and human nutrition worldwide.
Understanding the links between micro/nanoplastics-induced gut microbes dysbiosis and potential diseases in fish: A review
This review examines how microplastics and nanoplastics accumulate in fish intestines and disrupt their gut bacteria, potentially leading to inflammation, immune problems, and metabolic diseases. The disrupted gut microbiome can weaken the intestinal barrier, allowing harmful substances to enter the fish's body. Since fish are a major protein source for billions of people, understanding how microplastics damage fish gut health is important for assessing risks to human food safety.
Effect of nanoplastics on fish health and performance: A review
Researchers reviewed studies on nanoplastics (particles smaller than 100 nm) in fish and found evidence of tissue accumulation, impaired locomotion and foraging, immune and growth disruption, altered lipid metabolism, and neurotoxicity, though mortality and developmental malformations had not yet been reported.
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.
