Microplastics in decapod crustaceans: Accumulation, toxicity and impacts, a review
AI summary Read the abstract
This review summarizes research on microplastic contamination in decapod crustaceans like shrimp, crabs, and lobsters, which are widely consumed as seafood. Studies have found microplastics accumulating in their gills, digestive organs, and gut, with experimental evidence showing oxidative stress, immune damage, and reproductive toxicity. The findings raise concerns about potential human exposure to microplastics through seafood consumption.
The presence of microplastics in the aquatic environment poses a serious threat not only to aquatic organisms but also to human beings that consume them. The uptake and effects of microplastics have been studied in almost all groups of aquatic organisms. This review details the different aspects of microplastics exposure in an ecologically and economically important group of crustaceans, the Decapods. A majority of Decapod crustaceans such as prawns, shrimp, crabs, lobsters and crayfish are consumed as seafood and play important roles in food chains and food webs. Numerous studies are available on the accumulation of microplastics in tissues such as the gills, hepatopancreas and gastrointestinal tract in these organisms. Experimental studies have also highlighted the toxic effects of microplastics such as oxidative stress, immunotoxicity and reproductive and developmental toxicity in them. This review also summarizes the ecological impacts and implications in human beings as well as lacunae with regard to microplastic uptake in Decapods.

Microplastic pollution in wild populations of decapod crustaceans: A review
AI summary Read the abstract
Researchers reviewed the occurrence and characteristics of microplastics found in wild populations of decapod crustaceans including crabs and shrimps. They found that fibrous microplastics smaller than 1 mm were the most commonly detected type, and that edible portions generally contained fewer microplastics than non-edible parts. The review highlights the importance of understanding microplastic contamination in commercially valuable crustaceans for both ecological and food safety assessments.
Integrated toxicological approach to microplastics and nanoplastics in crustaceans
AI summary Read the abstract
This review summarizes existing research on microplastics and nanoplastics in crustaceans like crabs and shrimp. Studies show these particles build up in tissues including the gut and gills, causing cell damage, immune and hormone disruption, and changes in growth, molting, and reproduction, effects often worsened when combined with other pollutants.
Progress on the Effects of Microplastics on Aquatic Crustaceans: A Review
AI summary Read the abstract
This review examined the effects of microplastics on aquatic crustaceans, finding that microplastics negatively affect life history, behavior, and physiological functions including oxidative stress, immune responses, and reproductive output across multiple species.
Oxidative effects of consuming microplastics in different tissues of white shrimp Litopenaeus vannamei
AI summary Read the abstract
Researchers fed white shrimp diets containing polystyrene microplastics and found the particles accumulated in gills, muscles, and the hepatopancreas. The microplastics triggered oxidative stress, DNA damage, and lipid damage in multiple tissues, along with visible tissue abnormalities including edema and immune cell infiltration. The study demonstrates that dietary microplastic exposure can cause widespread oxidative harm across different organ systems in commercially important shellfish.
Assessing the impact of microplastics and nanoplastics on shrimp growth, physiology, antioxidant, immune responses and gut microbiota
AI summary Read the abstract
This review examines how microplastics and nanoplastics affect shrimp health, covering impacts on growth, immune function, gut bacteria, and antioxidant defenses. Researchers found that plastic exposure can impair shrimp physiology through multiple pathways, with implications for both aquaculture productivity and seafood safety. The study highlights the need for more research on how plastic pollution in coastal waters threatens shrimp populations that are important for both ecosystems and human nutrition.
