Ammonium Removal During Laboratory Culture of the Tehuelche ScallopAequipecten tehuelchus
This study tested the effectiveness of two macroalgal species at removing ammonium — a toxic nitrogen compound — from seawater in closed aquarium systems used for shellfish aquaculture research. Maintaining good water quality is essential for studying shellfish health responses to environmental stressors including microplastics.
Ocean Warming May Enhance Biochemical Alterations Induced by an Invasive Seaweed Exudate in the Mussel Mytilus galloprovincialis
Researchers found that elevated ocean temperatures amplified the biochemical disruptions caused by exudates from the invasive red seaweed Asparagopsis armata in the mussel Mytilus galloprovincialis. The findings suggest that ocean warming may worsen the impacts of biological invasions on native marine filter feeders.
Epimicrobiome Shifts With Bleaching Disease Progression in the Brown Seaweed Saccharina japonica
Researchers characterized shifts in bacterial communities on farmed kelp (Saccharina japonica) during bleaching disease progression, finding that disease stages showed distinct epimicrobial community changes with increased pathogen-associated taxa as bleaching severity worsened.
Effects of Vibrio vulnificus and Microcystis aeruginosa co-exposures on microplastic accumulation and depuration in the Eastern Oyster (Crassostrea virginica)
Researchers studied how exposure to harmful bacteria, including Vibrio and Microcystis species, affects the ability of Eastern oysters to accumulate and clear out microplastics. They found that bacterial co-exposure reduced the oysters' filtration rates, causing them to retain more microplastics for longer periods. The study suggests that climate-driven increases in harmful bacteria could worsen the microplastic burden in commercially important shellfish.
Polyethylene-induced gill alterations in Mytilus galloprovincialis and the mitigation potential of Chlorella vulgaris
Researchers exposed Mediterranean mussels (Mytilus galloprovincialis) to environmentally relevant concentrations of polyethylene microplastics and found histopathological and molecular gill alterations after 14–21 days, and showed that the microalga Chlorella vulgaris partially mitigated these toxic effects.
Harnessing seaweed farming for climate mitigation in South Korea: evaluating carbon dioxide removal potential and future research directions
Researchers evaluated the potential of seaweed farming as a carbon dioxide removal strategy in South Korea. They found that seaweed cultivation can sequester carbon through biomass storage and dissolved organic carbon release, while also substituting carbon-intensive products. The study suggests that scaling up seaweed aquaculture could contribute meaningfully to climate mitigation goals, though more research is needed on long-term carbon storage pathways.
Impact of microplastics on microbial diversity and pathogen distribution in aquaculture ecosystems: A seasonal analysis
Researchers studied bacteria growing on microplastics in fish farming waters and found that in summer, these plastic-attached communities became more connected and harbored several disease-causing species including Vibrio. Microplastics in aquaculture act as floating habitats for harmful bacteria, and seasonal warming makes this worse, raising concerns about seafood safety and the spread of infections to humans.
Development of a framework and toolbox for measuring and evaluating ecosystem interactions of seaweed aquaculture
This Dutch-language study (mostly in Dutch) developed a framework and toolbox for measuring ecosystem integrity in seaweed cultivation areas off the Dutch coast, relevant to scaling up sustainable aquaculture. Healthy coastal ecosystems with minimal microplastic contamination are important for sustainable seaweed production.
Contribution of seaweed farming to the mitigation of greenhouse gas emissions and microplastics pollution
Researchers reviewed how seaweed farming can help fight two major environmental problems: seaweed absorbs CO2 from the atmosphere without competing for agricultural land, and seaweed-derived polymers can be used to make biodegradable plastics that break down without generating persistent microplastics. Scaling up seaweed-based bioplastics remains limited by production costs, but the potential environmental benefits make further research worthwhile.
Polyamide microplastics can mitigate the effects of pathogenic bacterium on the health of marine mussels
Researchers examined how polyamide microplastics interact with the pathogenic bacterium Vibrio parahaemolyticus and their combined effects on marine mussels. Surprisingly, they found that higher concentrations of microplastics actually reduced the harmful effects of the bacteria on mussel health by adsorbing the pathogens. The study reveals that microplastic-bacteria interactions in the ocean are more complex than previously thought and do not always amplify toxicity.
Biological Responses of Oyster Crassostrea gasar Exposed to Different Concentrations of Biofloc
Researchers examined how oysters respond to different concentrations of biofloc, a microbial aggregate used in aquaculture systems. The study found that oyster filtration activity and biological responses varied with biofloc concentration, providing insights for integrating oysters into more sustainable multitrophic aquaculture systems.
Physiological and intestinal microbiota responses of sea cucumber Apostichopus japonicus to various stress and signatures of intestinal microbiota dysbiosis
Scientists tested how six common aquaculture stressors, including high temperature, low salinity, ammonia, and overcrowding, affect the gut health and microbial communities of sea cucumbers. All stressors reduced growth and digestive function while shifting the balance of gut bacteria, with potentially harmful bacteria increasing under several conditions. The study identified specific microbial ratio changes as signatures of gut disturbance, which could be useful markers for monitoring sea cucumber health in aquaculture.
Comparison of three unionid mussel species in removing green microalgae grown in recirculating aquaculture system effluent
This paper is not directly about microplastics; it tests whether three freshwater mussel species can filter and remove green microalgae grown in fish-farm wastewater, as part of a multi-trophic aquaculture nutrient-recycling system.

The study contributes to risk assessment frameworks that are essential for advancing public health understanding of these pathogenic bacteria in coastal environments.
Sea salt associated microplastics amplify pathogenic Vibrio and impair development in brine shrimp (Artemia franciscana)
Researchers found that microplastics present in harvested sea salt promoted biofilm formation by the pathogenic bacterium Vibrio harveyi and impaired the development of brine shrimp. The study suggests that microplastic contamination in sea salt could amplify pathogenic bacteria and increase infection risks in inland mariculture operations.
From Waste to Resource: Algal–Bacterial Systems and Immobilization Techniques in Aquaculture Effluent Treatment
This review examines algal-bacterial symbiotic systems combined with microbial immobilization techniques as sustainable alternatives for treating aquaculture wastewater containing nitrogen, phosphorus, antibiotics, and heavy metals, with emphasis on simultaneous pollutant removal and biomass valorization.
Combined effects of polyamide microplastics and the pathogenic bacterium Vibrio parahaemolyticus on the immune parameters of Mytilus coruscus
When mussels were exposed to nylon microplastics along with harmful Vibrio bacteria, they suffered gill damage, increased oxidative stress, and weakened immune defenses compared to either stressor alone. The combined exposure suppressed key immune enzymes that mussels need to fight infection. Since mussels are widely consumed as seafood, this study raises concerns that microplastic-contaminated shellfish could carry more pathogens and be less safe to eat.
Intertidal Concentrations of Microplastics and Their Influence on Ammonium Cycling as Related to the Shellfish Industry
Researchers determined the concentration and spatial distribution of microplastics in intertidal sediments at shellfish aquaculture sites and investigated their influence on ammonium cycling, finding that elevated microplastic concentrations altered nitrogen processing by benthic microbial communities. The results suggest microplastics at aquaculture densities may disrupt sediment nutrient dynamics with potential implications for shellfish productivity.
