ClearThe Evaluation of Microplastic Reduction in Biofloc Aquaculture for Sustainable Nile Tilapia Cultivation
Researchers evaluated biofloc technology as a strategy to reduce microplastic levels in water and Nile tilapia tissues in aquaculture, using ecological risk assessment to evaluate residual contamination. Biofloc systems reduced MP concentrations in both water and fish tissues compared to conventional systems, supporting biofloc technology as a partial mitigation strategy.
Study on the dynamics of microplastics in the biofloc system for Nile tilapia (Oreochromis niloticus) aquaculture
Researchers studied how microplastics behave in biofloc aquaculture systems — where beneficial bacteria clusters are used to improve water quality — finding that microplastics accumulate in both the bacterial clusters and tilapia tissues, with intestinal contamination rising sharply at higher plastic concentrations. The results show that biofloc technology does not protect fish from microplastic exposure and that plastic management is essential for safe aquaculture.

Biofloc Technology in Fish Aquaculture: A Review
This review examines biofloc technology, a method of fish farming that uses beneficial microbial communities to improve water quality and fish health. While not directly about microplastics, the technology is relevant because it could reduce the environmental footprint of aquaculture and potentially limit fish exposure to waterborne contaminants. Healthier aquaculture practices may help produce safer fish for human consumption in an era of increasing water pollution.
Impacts of Nile Tilapia (Oreochromis niloticus) exposed to microplastics in bioflocs system
Researchers assessed the effects of polystyrene microplastics on Nile tilapia raised in a bioflocs aquaculture system over 28 days. While the microplastics did not significantly affect water quality, fish growth, or digestive enzymes, they accumulated most heavily in the liver and increased markers of oxidative stress. The findings suggest that even in biofloc systems rich in beneficial microbes, microplastics can still accumulate in fish organs and cause subtle biological harm.
Microplastics biodegradation by biofloc-producing bacteria: An inventive biofloc technology approach
Researchers investigated biofloc-producing bacteria as a novel approach to biodegrade microplastics in aquaculture systems, finding that certain floc-forming bacterial strains can break down plastic particles while simultaneously improving water quality in culture environments.
Microplastics inhibit biofloc formation and alter microbial community composition and nitrogen transformation function in aquaculture
Microplastics were found to inhibit biofloc formation in aquaculture systems and alter microbial community composition and nitrogen transfer processes. The findings raise concerns about the growing use of intensive biofloc-based aquaculture in areas where microplastic contamination is prevalent.
Unraveling Microplastic-Biofilm Nexus in Aquaculture: Diversity and Functionality of Microbial Communities and Their Effect on Plastic Traits
Researchers incubated five common types of microplastics in an aquaculture pond for 128 days and found that biofilm formation varied significantly depending on the plastic type, with polypropylene and polyethylene supporting the richest microbial communities. PET microplastics attracted more plastic-degrading bacteria like Pseudomonas, while all plastic types enriched potentially pathogenic microorganisms. The findings highlight how different microplastics selectively shape microbial colonization in aquaculture environments, with implications for both environmental health and food safety.
Assessment of dietary polyvinylchloride, polypropylene and polyethylene terephthalate exposure in Nile tilapia, Oreochromis niloticus: Bioaccumulation, and effects on behaviour, growth, hematology and histology
Nile tilapia fish fed three common types of microplastics (PVC, polypropylene, and PET) showed reduced growth, abnormal behavior, blood cell damage, and tissue damage in their gills, liver, and intestines. The harmful effects increased with higher doses of microplastics and varied by plastic type. Since tilapia is one of the most widely consumed fish globally, these findings raise concerns about the health of fish that may carry microplastic contamination to human diets.
