Ion transport and metabolic regulation induced by nanoplastic toxicity in gill of Litopenaeus vannamei using proteomics
Researchers used proteomics to study how nanoplastics affect the gills of Pacific white shrimp, a widely farmed seafood species. They found that high concentrations of nanoplastics damaged gill tissue, disrupted ion balance, triggered oxidative stress, and altered energy metabolism. The study reveals the molecular mechanisms through which nanoplastic pollution may threaten the health of commercially important aquaculture species.
Toxicological effects of microplastics in Litopenaeus vannamei as indicated by an integrated microbiome, proteomic and metabolomic approach

Effects of microplastics on gene expression to nonspecific immune system in pacific white shrimp (Litopenaeus vannamei).
This study found that high-density polyethylene microplastic particles in shrimp feed suppressed immune defense genes in Pacific white shrimp and caused intestinal and gill tissue damage at concentrations well below lethal levels. The findings suggest that microplastic exposure could compromise immune function and health in farmed crustaceans.
Polystyrene nanoplastics exposure alters muscle amino acid composition and nutritional quality of Pacific whiteleg shrimp (Litopenaeus vannamei)
Researchers exposed Pacific whiteleg shrimp to polystyrene nanoplastics at various concentrations for 28 days and measured changes in muscle nutritional quality. They found that higher nanoplastic concentrations reduced growth rates, lowered protein content, and altered the amino acid composition of the shrimp's edible muscle tissue. The study suggests that nanoplastic pollution in aquaculture environments could diminish the nutritional value of farmed seafood.
Oxidative effects of consuming microplastics in different tissues of white shrimp Litopenaeus vannamei
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.
Transcriptomic analysis following polystyrene nanoplastic stress in the Pacific white shrimp, Litopenaeus vannamei
Researchers used transcriptomic analysis to study how polystyrene nanoplastics affect gene expression in Pacific white shrimp. They found that nanoplastic exposure activated lysosome pathways and disrupted genes involved in immune response, protein processing, and metabolism. The study provides molecular-level evidence that nanoplastics can interfere with multiple biological systems in commercially important shrimp species.
Ecotoxicoproteomic assessment of microplastics and plastic additives in aquatic organisms: A review
This review examines how proteomics — the large-scale study of proteins — is being applied to understand the toxic effects of microplastics and plastic additives on aquatic organisms, and how this data can feed into adverse outcome pathway frameworks for ecological risk assessment.
Microplastics weaken the exoskeletal mechanical properties of Pacific whiteleg shrimp Litopenaeus vannamei
Researchers discovered that environmentally realistic levels of microplastics weakened the shells of whiteleg shrimp by disrupting the structure of chitin, the main building material in crustacean exoskeletons. The microplastics also embedded in the shell surface and altered key genes and metabolites involved in shell formation. Since shrimp is a widely consumed seafood, this finding raises questions about both the quality of farmed shrimp and the potential for microplastic transfer to human consumers.
Length-dependent impacts of fibrous microplastics on Pacific white shrimp (Penaeus vannamei) determined using multi-omics approach
White shrimp (Penaeus vannamei) exposed to short versus long PET microfibers showed length-dependent toxicological responses assessed by transcriptomics and metabolomics, with shorter fibers causing greater oxidative stress, immune disruption, and metabolic disturbance than longer ones.
Microplastic toxicity in shrimp: From mechanistic pathways to ecological implications.
Researchers systematically reviewed 94 studies on microplastic toxicity in shrimp, mapping mechanistic pathways from particle characteristics to oxidative stress, immune dysfunction, neurotoxicity, and reproductive impairment across hepatopancreas, gills, gut, and gonad tissues, and identifying shrimp as effective bioindicators for aquatic microplastic risk assessment.
Effect of polyethylene microplastics on oxidative stress and histopathology damages in Litopenaeus vannamei
Researchers injected fluorescent polyethylene microspheres into Pacific white shrimp (Litopenaeus vannamei) and found that microplastic exposure increased oxidative stress markers and caused histopathological damage to hepatopancreas and gill tissue, even at relatively low concentrations.

Insight into the immune and microbial response of the white-leg shrimp Litopenaeus vannamei to microplastics
Researchers exposed white-leg shrimp (Litopenaeus vannamei) to different concentrations of microplastics for 48 hours and measured immune and microbial responses. The study found that high microplastic concentrations significantly reduced survival rates, altered immune-related gene expression, and disrupted the gut microbial community, suggesting that microplastic pollution may compromise shrimp immune function.
Weathered High Density Polyethylene Microplastics Induce Proximate Imbalance in the Post Larval Stages of Litopenaeus vannamei
Researchers exposed post-larval shrimp to weathered high-density polyethylene microplastics for 45 days and measured changes in nutritional composition including protein, fat, fiber, and ash content. All proximate constituents decreased significantly during exposure, and a 15-day recovery period showed no signs of recovery from the microplastic-induced stress. The study suggests that microplastic contamination can impair the growth and nutritional quality of commercially important shrimp species.

Researchers fed Pacific white shrimp diets contaminated with high-density polyethylene microplastics and observed dose-dependent immune suppression and organ damage. The microplastics disrupted the expression of antioxidant enzyme and lysozyme genes and caused significant histopathological changes in the hepatopancreas. The study demonstrates that dietary microplastic exposure can compromise the immune defenses of commercially important crustaceans, potentially increasing their susceptibility to disease.
Evidence of Marine Microplastics in Commercially Harvested Seafood
Researchers assessed microplastic contamination in three commercially available shrimp species purchased from supermarkets in South Australia. They found microplastics present in the digestive tracts of all species examined, with fibers being the most commonly identified type.
