Microplastics and their potential effects on the aquaculture systems: a critical review
AI summary Read the abstract
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.
Abstract According to the statistics, 8.3 billion metric tonnes of plastics have been produced since 1950s, which is far more than other synthetic materials and the annual production which are about 500 million tonnes per year at present. The production of plastics makes microplastics pollution extremely widespread distribution, which will have a lasting impact on the global environment, especially on the aquaculture systems. And the distribution of the microplastics is extremely imbalanced around the global waters. In the present review, we have summarized the development of aquaculture in the World and China based on the existing data sources. And the total aquaculture production of the World will over 90 million tonnes, which will exceed the capture production in 2020. Aquaculture products will become one of the most important sources of high‐quality protein. However, we found that many kinds of microplastics are detected and enriched in both farmed and captured species. Both endogenous and exogenous factors like the use of fishing plastic products, factory farming facility and equipment, natural and synthetic feed, animal health products, aquaculture fortifier and aquatic food additives make accumulation of microplastics easier. In addition, the safety of aquaculture products is closely related to human health because the residues of microplastics in fish leading to various potential hazards. In summary, this paper reviewed the relationship between microplastics and aquaculture, aimed at calling for the rational and restricted use of plastic products in the aquaculture ecosystems.

Occurrence and ecological impact of microplastics in aquaculture ecosystems
AI summary Read the abstract
This review examines microplastic contamination specifically within aquaculture systems, which are an increasingly important source of protein for human diets worldwide. Researchers found that aquaculture environments accumulate microplastics from external sources like land-based waste and shipping, as well as from the plastic gear, equipment, and feed used in farming operations. The study raises concerns about food safety, as microplastics in farmed seafood represent a direct pathway of human exposure.

Understanding the sources, fate and effects of microplastics in aquatic environments with a focus on risk profiling in aquaculture systems
AI summary Read the abstract
This review summarizes how microplastics enter aquaculture systems and accumulate in farmed fish, causing toxic effects including immune disruption, oxidative stress, and genetic damage. Since farmed fish are a major food source, the buildup of microplastics in aquaculture poses a direct pathway for these particles to reach human diets.
