Microplastics in Aquaculture
Summary
This review examines how microplastic accumulation in water bodies threatens aquaculture by affecting fish and shellfish growth, reproduction, behavior, and survival, with marine bycatch used as fishmeal identified as a key pathway for microplastic entry into aquaculture feed systems. The authors assess the extent of microplastic invasion into commercial aquaculture operations and the implications for seafood safety.
Microplastics accumulation in waterbodies posing a serious threat to aquaculture. Effects on growth, reproduction, behavioural changes and mortality are some of the noticed factors which has been reported by many researchers worldwide. The success of commercial aquaculture totally depends on external feed input, with fish meal comprising a major ingredient of these feeds. It is evident that marine by catch, which is used as fish meal, is the biggest contributor of these microplastics which are entering into the aquaculture system without our knowledge. Now, microplastics have already invaded the aquaculture system. The short-term and long-term implications of these microplastics are yet to be established. The present review will iterate on the major entry of these microplastics in the aquaculture system and their potential implication.

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.
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.
Occurrence and ecological impact of microplastics in aquaculture ecosystems
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.
Microplastics in fishmeal: A threatening issue for sustainable aquaculture and human health
Researchers reviewed how microplastics enter aquaculture systems through contaminated fishmeal — made from wild-caught fish that have ingested ocean plastics — and accumulate in farmed fish that are then eaten by humans. The review calls for improved microplastic screening during fish feed production to protect both aquaculture sustainability and public health.
A review of microplastic pollution in aquaculture: Sources, effects, removal strategies and prospects
This review examines how microplastics contaminate fish farms through environmental inputs and aquaculture equipment, affecting water quality and the health of farmed seafood. Since contaminated aquaculture products are a direct pathway for microplastics to reach the human diet, reducing plastic pollution in fish farming is important for food safety.
