ClearMicroplastic pollution budget assessment of different integrated multi-trophic aquaculture (imta) systems
Researchers assessed the microplastic pollution budget of integrated multi-trophic aquaculture systems as part of the ASTRAL project, examining both microplastic release from synthetic materials used in aquaculture infrastructure — including ropes, pipes, and equipment — in open and recirculating systems and the contribution of marine-derived plastic sources. The study aimed to quantify the role of diverse aquaculture operations in local and global microplastic emissions, for which accurate estimates have remained unknown.
Microplastics in aquaculture environments: Sources, pollution status, toxicity and potential as substrates for nitrogen-cycling microbiota
Researchers reviewed microplastic pollution in aquaculture systems, finding concentrations as high as 362 particles per liter in water and nearly 125,000 per kilogram in sediment, with microplastics accumulating in farmed fish and shellfish and potentially reaching humans through the food chain.

Researchers examined recirculating aquaculture system (RAS) infrastructure as a source of microplastics, building a polymer and additive reference library from known plastic components to identify and quantify microplastic generation and removal within aquaculture facility water treatment processes.
Searching for SMART(er) solutions: A laboratory-assessment of microplastic release from aquaculture nets and ropes
Researchers tested aquaculture and fishing gear under simulated in-water abrasion to measure microplastic release rates under realistic operational conditions. The study found that net and rope materials shed substantial quantities of microplastics through routine mechanical wear.
Aging processes and microplastic release behavior of aquaculture implements
Researchers studied how four types of plastic aquaculture equipment age and release microplastics under simulated marine conditions over 16 weeks. They found that PVC buoys released the most microplastic particles, followed by polypropylene cables, polyethylene nets, and PET buoys, with all materials developing increasingly rough surfaces, cracks, and oxygen-containing chemical groups during aging. The study provides guidance for selecting aquaculture materials that minimize microplastic pollution in marine environments.
Searching for SMART(er) solutions: A laboratory-assessment of microplastic release from aquaculture nets and ropes
This laboratory study simulated mechanical abrasion of plastic fishing gear and aquaculture equipment to quantify microplastic emissions, addressing the fisheries sector as a poorly characterized source of marine microplastic pollution. Abrasion of plastic gear released measurable quantities of particles, with emission rates varying by material type and abrasion conditions.
An Integrated Approach to Assessing the Potential of Plastic Fishing Gear to Release Microplastics
Researchers developed an integrated approach to assess how abandoned, lost, or discarded fishing gear releases microplastics into marine environments. The study found that fishing gear is a significant but understudied source of microplastic pollution, and the research provides new methods for quantifying microplastic release from different types of plastic fishing equipment.
Plastic Pollution and Microplastics as Emerging Threats to Aquaculture: A Narrative Review
This narrative review examined how microplastic contamination has emerged as a major challenge for aquaculture, identifying MPs in pond water, sediments, fish feeds, and cultured organisms. The review discussed MP sources from degraded infrastructure and contaminated inputs, and assessed the implications for farmed fish health and seafood safety.
Microplastics in aquaculture systems: Occurrence, ecological threats and control strategies
This review summarizes how microplastics contaminate aquaculture systems through fishing gear, feed, and polluted water, and examines their effects on farmed aquatic species. Microplastics accumulate in farmed fish and shellfish, raising concerns about food safety for the millions of people who consume aquaculture products. The authors discuss removal strategies and call for better monitoring to protect both aquaculture sustainability and consumer health.
Identification and Quantification of Microplastics in Aquaculture Environment
This review covers high-efficiency analytical methods for identifying and quantifying microplastics in aquaculture environments, addressing the growing concern that plastic products widely used in aquaculture operations are an underreported source of microplastic contamination.
Microplastics and their potential effects on the aquaculture systems: a critical review
This review examines the sources, distribution, and potential ecological effects of microplastics in aquaculture systems worldwide. Researchers found that microplastics enter aquaculture through feed, water intake, and atmospheric deposition, and can accumulate in farmed fish and shellfish tissues. The study highlights the need for monitoring programs and mitigation strategies to protect both aquaculture productivity and consumer safety from microplastic contamination.
A holistic approach to plastic pollution in integrated multi-trophic aquaculture facilities: Plastic ingestion in Sparus aurata and Mytilus galloprovincialis
Researchers investigated plastic ingestion in sea bream (Sparus aurata) and mussels (Mytilus galloprovincialis) at experimental integrated multi-trophic aquaculture (IMTA) facilities in Mallorca, finding plastics in 33% of fish, 94% of mussels, and 100% of surface water samples, with mussels ingesting twice as much plastic as fish and the species differing markedly in particle type and composition.
