ClearTemporal variability of microplastics in shrimp (Litopenaeus vannamei), feed, water and sediments of coastal and inland culture ponds
This study tracked microplastic contamination in farmed shrimp, their feed, water, and pond sediment across 12 shrimp farms in India over a four-month growing period. Microplastics were found in over 93% of shrimp samples, with feed identified as the primary source of contamination. Since shrimp are one of the most widely consumed seafood products globally, these findings raise concerns about microplastic exposure for consumers.
Microplastic study on (litopenaeus vannamei) cultivation enterprises on the east coast of aceh
Researchers sampled vannamei shrimp (Litopenaeus vannamei) from three cultivation stations on Aceh's east coast (Pidie, Pidie Jaya, and Bireuen) and analyzed microplastic content using H2O2/H2SO4 digestion and microscopy at 40x magnification. They found fiber and film microplastics in all shrimp samples, with the highest count (13 particles) at the Pidie station, indicating microplastic contamination has entered commercial aquaculture supply chains.
Characterization of Microplastic Contamination of Whiteleg Shrimp (Litopenaeus vannamei) Cultivation in North Lombok, Indonesia
Researchers characterized microplastic contamination in farmed whiteleg shrimp (Litopenaeus vannamei), measuring particle abundance, size distribution, polymer types, and potential human dietary exposure through shrimp consumption. Microplastics were found throughout shrimp tissues, with implications for seafood safety.
Farmed stage (age)-dependent accumulation and size of microplastics in Litopenaeus vannamei shrimp reared in a super-intensive controlled system
Researchers tracked microplastic accumulation in farmed shrimp over their entire growth cycle and found that both the number and size of microplastic particles increased as the shrimp grew older. Shrimp raised in super-intensive indoor systems had higher microplastic contamination than those from traditional ponds or wild environments, likely due to the extensive plastic materials used in the farming infrastructure. Since shrimp is widely consumed seafood, these findings mean that people eating farmed shrimp are likely consuming microplastics that accumulated throughout the animals' lives.
Growth of Vannamei Shrimp (Litopenaeus vannamei) in Intensive Cultivation Systems
Not relevant to microplastics — this descriptive study tracks the growth performance and water quality parameters in intensive Litopenaeus vannamei (vannamei shrimp) aquaculture ponds in Indonesia.
The occurrence of pollutants in organisms and water of inland mariculture systems: Shrimp aquaculture is a procession of Microplastics accumulation
This study examined microplastic contamination in water and shrimp at different stages of both pond-based and industrial inland aquaculture systems, finding that shrimp accumulated microplastics throughout the production cycle. The results establish shrimp aquaculture as a notable pathway for microplastic transfer into the food supply.
Occurrence and Characteristics of Microplastics in Wild and Farmed Shrimps Collected from Cau Hai Lagoon, Central Vietnam
Researchers measured microplastic occurrence in the gastrointestinal tracts and tissues of four shrimp species (two wild, two farmed) from a Vietnamese lagoon, finding microplastics in all species and providing baseline data on seafood plastic contamination for this region.
Microplastics in the tissues of commercial semi-intensive shrimp pond-farmed Litopenaeus vannamei from the Gulf of California ecoregion
Researchers conducted the first study of microplastics in the gastrointestinal tract, gills, and exoskeleton of farmed whiteleg shrimp from commercial aquaculture facilities in northwestern Mexico. The study found an average of 18.5 microplastic items per shrimp across all tissues examined. The findings suggest that semi-intensive shrimp farming operations are a source of microplastic contamination in commercially harvested seafood.
Microplastics in surface water and tissue of white leg shrimp, Litopenaeus vannamei, in a cultured pond in Nakhon Pathom Province, Central Thailand
Researchers detected microplastics in the surface water and edible tissues of white leg shrimp (Litopenaeus vannamei) farmed in Thailand, raising food safety concerns about microplastic contamination in a commercially important aquaculture species consumed widely across Asia.
Isolation and Analysis of Microplastics in Vaname Shrimp (Litopenaeus vannamei Boone, 1931) at Tanjung Luar Fish Landing Base, East Lombok Regency
Researchers isolated and analyzed microplastics from vaname shrimp (Litopenaeus vannamei) collected at Tanjung Luar fish landing base in East Lombok, Indonesia. Microplastics were detected in shrimp digestive systems, raising food safety concerns given the direct pathway to human consumption through seafood.
Microplastic Analysis in Vannamei Shrimp Ponds in Kandang Semangkon Village, Paciran, Lamongan, East Java, Indonesia
Researchers analysed the abundance, types, and colours of microplastics in water and shrimp tissue at vannamei shrimp ponds in East Java, Indonesia, and examined the relationship between total suspended solids and microplastic presence across two sampling stations.
A critical review of microplastics in the shrimp farming environment: Incidence, characteristics, effects, and a first mass balance model
This review provides the first mass balance model for tracking how microplastics flow through shrimp farming systems, from water and feed inputs to accumulation in shrimp tissues and sediments. Researchers found that microplastics can act as carriers for other contaminants and accumulate in shrimp at levels that may pose risks to consumers. The study identifies critical knowledge gaps in understanding how aquaculture practices contribute to microplastic contamination in farmed seafood.
Accumulation and damage of polyethylene-microplastics to the digestive system of juvenile Litopenaeus vannamei shrimp exposed through feed
Researchers fed juvenile Pacific white shrimp diets containing polyethylene microplastics at varying concentrations for 28 days. While survival and growth were not affected, microplastics accumulated in the digestive system and caused tissue damage to the hepatopancreas and intestine, suggesting that even without visible growth effects, microplastic ingestion can cause internal harm to commercially important crustacean species.
A preliminary study of the association between colonization of microorganism on microplastics and intestinal microbiota in shrimp under natural conditions
Microplastics were detected in shrimp pond sediment (5,129 ± 1,176 items/kg) and in Litopenaeus vannamei shrimp tissue (14.08 ± 5.70 items/g), with MP abundance positively correlated between sediments and shrimp, and the microbiome on plastic surfaces differing from the shrimps' intestinal microbiota.
Detection of Microplastics by Various Types of Whiteleg Shrimp (Litopenaeus vannamei) in the Korean Sea
Researchers detected microplastics in whiteleg shrimp from Korean seas, finding 1.73 to 3.8 particles per 10 grams across different shrimp sizes, with fibers and fragments of various polymer types predominantly concentrated in the heads and intestines.
Detection of microplastics in Litopenaeus vannamei (Penaeidae) and Macrobrachium rosenbergii (Palaemonidae) in cultured pond
Researchers detected microplastics in the gastrointestinal tracts of cultured whiteleg shrimp and giant river prawns from aquaculture ponds. The findings indicate that consuming these shellfish without removing the digestive tract is one pathway by which humans may be exposed to microplastics. The study suggests that microplastics in freshwater aquaculture species can transfer through the food chain to human consumers.
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.
Impacts of microplastics on three different juvenile shrimps: Investigating the organism response distinction
The responses of three farmed shrimp species — Penaeus monodon, Marsupenaeus japonicus, and a third species — to microplastic exposure were compared to investigate species-specific effects. Results showed differences in sensitivity and biological response among the three shrimp species, indicating that microplastic risk assessments for aquaculture cannot assume uniform impacts across species.
Microplastic contamination in wild shrimp Litopenaeus vannamei from the Huizache-Caimanero Coastal lagoon, SE Gulf of California
Researchers found microplastics — predominantly fibers and fragments — in the gastrointestinal tracts, gills, and exoskeletons of wild shrimp from a Gulf of California coastal lagoon, with the gut containing far higher concentrations than other tissues, raising food safety concerns for human consumers.
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.
