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.
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.
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.
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.
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.
Microplastic Exposure and Distribution in the Coastal Aquaculture Input System
This paper appears to study microplastic exposure and distribution in coastal aquaculture systems, but the abstract contains no content beyond identifying the audience as international. Without a substantive abstract, it is not possible to provide a meaningful summary of the findings.
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.
Can we quantify the aquatic environmental plastic load from aquaculture?
Researchers developed the first framework for estimating plastic litter entering the ocean from aquaculture, combining satellite imagery, drone surveys, and questionnaire data from farms. The framework provides a method for quantifying a significant and previously untracked source of marine plastic pollution, which is important for both environmental monitoring and sustainable aquaculture management.
Risk of aquaculture-derived microplastics in aquaculture areas: An overlooked issue or a non-issue?
This review examines aquaculture-derived microplastics from degrading fishing nets and foam buoys, finding they represent a significant but overlooked source of marine microplastic pollution with distinct environmental consequences compared to other sources.
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 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.
How Relevant Are Direct Emissions of Microplastics into Freshwater from an LCA Perspective?
This study assessed the relevance of direct microplastic emissions into freshwater from a life cycle assessment perspective, providing initial inventory data and identifying key knowledge gaps needed to incorporate microplastic impacts into environmental assessments.
Role of recirculating aquaculture systems (RAS) in the generation and removal of microplastics and additives chemicals
Researchers investigated the generation and presence of microplastics and additive chemicals within recirculating aquaculture system (RAS) infrastructure by building a reference library of plastic sources and conducting targeted analysis of intake water, recirculating water, sludge, fish, and fish feed. Results identified plastic infrastructure and consumables as potential microplastic sources, though detected levels above 300 µm were low.
Workshop on Microplastics in the Coastal Aquaculture Input Chain: From the Perspectives of Policy, Regulation and Research to a Recommendation of a Mitigation Plan
Researchers and policymakers convened a workshop to address microplastic contamination in the coastal aquaculture supply chain — the equipment, feed, and materials used in fish and shellfish farming — and developed recommendations for mitigation strategies. The workshop bridged perspectives from regulation, science, and industry to propose practical steps for reducing plastic pollution at the source.
Occurrence, distribution and sources of microplastics in typical marine recirculating aquaculture system (RAS) in China: The critical role of RAS operating time and microfilter
This study found microplastics in all parts of fish farming systems in China, including the feed, water, and the fish themselves. Systems that had been running longer accumulated more microplastics, and the plastic types found in fish closely matched those in their feed and water. The findings suggest that farmed fish -- a major protein source -- can be a route of microplastic exposure for people who eat seafood.
