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.
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.
Analysis of Microplastic Contamination in Vaname Shrimp (Litopenaeus Vannamei) with Different Cultivation Methods
Researchers analyzed microplastic contamination across three different vaname shrimp (Litopenaeus vannamei) cultivation methods, sampling water, sediment, commercial feed, and shrimp tissues over three months. The study aimed to identify which cultivation system introduces more microplastics into the production environment and assess potential contamination routes for farmed shrimp.
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.
Distribution Patterns and Human Exposure Risks of Microplastics in Dominant Wild Edible Shrimp: A Case Study of Haizhou Bay Marine Ranch
Researchers surveyed microplastic contamination in dominant wild shrimp species in Haizhou Bay, China, characterizing the types, sizes, and concentrations of MPs found in their bodies and assessing the human dietary exposure risks from consuming these economically important seafood species.
Temporal 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.
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.
Microplastic Contamination in Shrimps from the Negombo Lagoon—Sri Lanka
Researchers analyzed microplastic contamination in two species of shrimp from Sri Lanka's Negombo Lagoon, examining both gastrointestinal tracts and gills. The study found microplastics present in all sampled shrimp, raising concerns about human dietary exposure to microplastics through seafood consumption in coastal communities.
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.
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.
Threats of Microplastic Pollution on Aquaculture Activities in Indonesia
This review examined microplastic contamination in Indonesian aquaculture systems, including shrimp, fish, and seaweed farms. Microplastics were found in aquaculture environments and organisms throughout Indonesia, threatening both ecosystem health and seafood safety. The paper calls for better monitoring and management of plastic pollution in Indonesia's extensive aquaculture sector.
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. The findings suggest that commercially harvested seafood represents a potential pathway for human dietary exposure to microplastics.
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.
Isolation and Analysis of Microplastics in Feather Clams (Anadara antiquata) at Tanjung Luar Fish Landing Base, East Lombok Regency
Researchers isolated and characterized microplastics from feather clam tissues collected at Tanjung Luar fish landing base in East Lombok, Indonesia. Multiple microplastic types were found in the soft tissues of bivalves that are regularly consumed by local communities, raising food safety concerns for this seafood-dependent coastal population.
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.
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.
