The study suggests these natural dietary supplements could support healthier, more sustainable shrimp farming practices.
Effects of nanoplastics on the gut microbiota of Pacific white shrimp Litopenaeus vannamei
Researchers fed polystyrene nanoplastics to Pacific white shrimp and found significant damage to their gut bacteria, intestinal structure, and immune system. The nanoplastics increased harmful bacteria like Vibrio while reducing beneficial species, and visibly damaged the intestinal lining. Since shrimp are widely consumed seafood, these gut health disruptions raise questions about how nanoplastic contamination in farmed and wild shrimp could affect both the animals and the people who eat them.

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.
The use of chitosan as an antioxidant in the feed of cultivated P. vannamei shrimp against oxidative stress induced by exposure to microplastics
Researchers tested whether adding chitosan to shrimp feed could protect farmed shrimp from oxidative stress caused by microplastic exposure. They found that chitosan supplementation helped counteract the harmful oxidative effects of microplastics on shrimp tissues. The findings suggest that natural antioxidants like chitosan could be a practical strategy for reducing microplastic-related damage in aquaculture.

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.
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.
The effects of replacing fishmeal by mealworm ( Tenebrio molitor ) on digestive enzymes activity and hepatopancreatic biochemical indices of Litopenaeus vannamei
Researchers examined the effects of partially or fully replacing fishmeal with mealworm (Tenebrio molitor) meal in the diet of Pacific white shrimp, evaluating impacts on digestive enzyme activity and hepatopancreatic biochemical indices. The study found that moderate substitution levels were feasible without significant negative effects on shrimp physiology.
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.
The effects of replacing fishmeal by mealworm ( Tenebrio molitor ) on digestive enzymes activity and hepatopancreatic biochemical indices of Litopenaeus vannamei
Researchers found that replacing up to 30% of fishmeal with mealworm (Tenebrio molitor) meal in Pacific white shrimp diets improved antioxidant enzyme activity, reduced oxidative stress markers, and enhanced digestive enzyme activity, suggesting mealworm is a viable sustainable protein substitute in shrimp aquaculture.
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.
Microplastic-Contaminated Feed Interferes with Antioxidant Enzyme and Lysozyme Gene Expression of Pacific White Shrimp (Litopenaeus vannamei) Leading to Hepatopancreas Damage and Increased Mortality
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.
Diversity of phytoplankton in the whiteleg (Litopenaeus vannamei) shrimp ponds in the south coastal area of Pangandaran, Indonesia
This Indonesian study assessed phytoplankton diversity and water quality in shrimp ponds using different farming intensities, finding that phytoplankton community composition serves as a useful bioindicator of pond health and productivity. Healthy aquaculture ecosystems are relevant to food safety given that farmed seafood is increasingly being found to contain microplastics from contaminated water.

Researchers tested Spathoteredo obtusa (a mangrove wood-boring bivalve) ethanol extract as a dietary immunostimulant in whiteleg shrimp challenged with Vibrio parahaemolyticus, finding the optimal 600 mg/L dose significantly improved immune parameters and survival against the bacterial pathogen.
Polystyrene nanoplastics induce lipid metabolism disorder and alter fatty acid composition in the hepatopancreas of Pacific whiteleg shrimp (Litopenaeus vannamei)
Researchers exposed Pacific whiteleg shrimp to different concentrations of polystyrene nanoplastics for 28 days and found significant disruption to fat metabolism in the shrimp's digestive organ. Higher concentrations caused tissue damage, reduced protein and fat content, and altered the activity of enzymes that control how the body processes fats. Since shrimp is a widely consumed seafood, these findings raise questions about how nanoplastic contamination in aquaculture could affect the nutritional quality and safety of shellfish for human consumption.
