ClearMonitoring plastics in the Mediterranean Sea with an emerging commercial species, the deep-water rose shrimp (Parapenaeus longirostris).
This study continued monitoring microplastic contamination in deep-sea Mediterranean crustaceans including Aristeus antennatus and Nephrops norvegicus, assessing these commercially important species as indicators of plastic pollution in deep-water ecosystems. Both crustacean species consistently contained microplastics, confirming contamination persists across monitoring periods.
Detection of microplastic fibers tangle in deep-water rose shrimp (Parapenaeus longirostris, Lucas, 1846) in the northeastern Mediterranean Sea
Researchers detected microplastic fibers — at an average of 18.8 particles per individual — in 100% of deep-water rose shrimp sampled from two sites in the northeastern Mediterranean, indicating pervasive microplastic contamination even in deep-sea commercial crustaceans.
Microplastics and Alien Black Particles as Contaminants of Deep-Water Rose Shrimp (Parapenaeus longistroris Lucas, 1846) in the Central Mediterranean Sea
Microplastics and unidentified black particles were found in the gastrointestinal tracts of deep-water rose shrimp caught in the central Mediterranean Sea, with nearly 15% of individuals containing plastic. The results add to evidence that microplastic ingestion is widespread in commercially harvested crustaceans, which raises concerns about human exposure through seafood consumption.
Microplastics in the crustaceans Nephrops norvegicus and Aristeus antennatus: Flagship species for deep-sea environments?
Researchers found microplastics in 83% of Norwegian lobster (Nephrops norvegicus) and the majority of shrimp (Aristeus antennatus) collected from deep-sea sites around Sardinia at depths of 270-660 m, identifying over 2000 microplastic-like particles by μFT-IR, suggesting deep-sea crustaceans could serve as flagship indicators of microplastic contamination.
Comparing microplastic ingestion in two commercial crustacean species, Aristaeomorpha foliacea and Parapenaeus longirostris: a sympatric case study from Western Mediterranean Sea
Researchers compared microplastic ingestion between two sympatric deep-sea shrimp species, Aristaeomorpha foliacea and Parapenaeus longirostris, from the Western Mediterranean Sea, coupling stable isotope analysis with microplastic characterization to examine how trophic position influences plastic uptake. The study provided insights into how microplastic pollution interacts with trophic dynamics in commercially important crustacean species.
Comparative assessment of microplastic ingestion among deep sea decapods: Distribution analysis in Sardinian and Catalan waters
Researchers examined microplastic ingestion in four species of deep-sea shrimp and lobster from the Mediterranean Sea, finding that nearly 73% of the animals had consumed microplastics. Fiber-shaped microplastics were by far the most common type found, and contamination levels varied between species and regions. The study shows that even deep-sea crustaceans consumed by humans are exposed to significant microplastic pollution.
Spatial occurrence and effects of microplastic ingestion on the deep-water shrimp Aristeus antennatus
Researchers found that 39% of deep-water shrimp (Aristeus antennatus) sampled across the Mediterranean contained microplastics in their stomachs, with ingestion rates reaching 100% near Barcelona, and that microfibers were likely retained long-term due to stomach morphology — though no measurable effects on the shrimps' physical condition were detected.
Comparing microplastic ingestion in two commercial crustacean species, Aristaeomorpha foliacea and Parapenaeus longirostris: a sympatric case study from Western Mediterranean Sea
Researchers examined microplastic ingestion in two sympatric deep-water shrimp species — Aristaeomorpha foliacea and Parapenaeus longirostris — collected from the same haul off the coast of Rome, combining stable isotope analysis of muscle tissue from 80 specimens with gastrointestinal tract analysis from 100 specimens subjected to chemical digestion. The study aimed to link trophic level and niche differences between the two economically important Mediterranean species to differences in their microplastic ingestion rates.
The Plastic Signature: Microplastic Ingestion and Phthalate Exposure in Parapenaeus longirostris from Three Tyrrhenian Sites (Mediterranean Sea)
Researchers simultaneously investigated microplastic ingestion and phthalate body burden in the deep-water shrimp Parapenaeus longirostris collected from three Mediterranean coastal areas. MPs were detected in 45% of specimens and urinary phthalate metabolites were elevated, establishing a direct link between seafood MP contamination and human phthalate exposure through consumption.
Microplastics ingestion by deep-sea decapod crustaceans from the Western Mediterranean
Researchers analyzed microplastic ingestion in four deep-sea decapod crustacean species collected from Sardinian and Catalan Mediterranean waters, dissecting gastrointestinal tracts from 210 individuals and characterizing ingested particles. They found microplastics in approximately 70% of examined specimens, revealing significant ingestion of microplastics by deep-sea benthic crustaceans and differences between Mediterranean regions, highlighting contamination of previously understudied deep-sea fauna.
Microplastic ingestion and retention in penaeid shrimp from the Arabian Sea
Researchers examined the digestive tracts of four commercially harvested shrimp species from the Arabian Sea coast of India and found microplastics in all four, including fibers, pellets, spheres, and fragments made of polyethylene, polystyrene, and other common plastics — providing baseline contamination data for an important seafood source.

Researchers found widespread plastic ingestion in deep-sea giant red shrimp from the Eastern Ionian Sea, with microplastics detected throughout digestive tracts, raising concerns about both stock health and human food safety.
Microplastics ingestion by deep-sea decapod crustaceans from the Western Mediterranean
Researchers investigated microplastic ingestion by four deep-sea decapod crustacean species in the Sardinian and Catalan regions of the Western Mediterranean, analyzing gastrointestinal tracts from 210 individuals to assess abundance, characterization, and species- and region-level differences, finding ingestion prevalence of approximately 70%.
Fiber entanglements as a proxy for anthropogenic pollution uptake: Monitoring deep-water rose shrimp (Parapenaeus longirostris) throughout the year.
Researchers monitored deep-water rose shrimp (Parapenaeus longirostris) across the year to assess whether fiber entanglements in their gill regions could serve as an indicator of anthropogenic pollution uptake. Fiber counts varied seasonally and tracked known pollution gradients, supporting their use as a practical proxy for monitoring microfiber exposure in commercial marine crustaceans.
Microplastics in shrimps: a study from the trawling grounds of north eastern part of Arabian Sea
Researchers examined three species of shrimp from trawling grounds in the Arabian Sea and found microplastics in every individual tested, with an average of nearly seven particles per shrimp. Fibers were the most common type of microplastic found, and six different plastic polymers were identified in the shrimps' digestive tracts. The findings confirm that microplastic contamination is widespread in commercially important seafood species, raising questions about potential transfer to human consumers.
Consistent microplastic ingestion by deep-sea invertebrates over the last four decades (1976–2015), a study from the North East Atlantic
Researchers found consistent microplastic ingestion by deep-sea invertebrates in the North East Atlantic over a 40-year period from 1976 to 2015, demonstrating that microplastic contamination of remote deep-sea habitats is a long-standing and persistent problem.
Occurrence and human exposure risk of microplastics in commercially important shrimp species from Northeastern Mediterranean Sea
Researchers examined three commercially important shrimp species from the Northeastern Mediterranean Sea and found microplastics in their digestive organs, primarily polyethylene and polypropylene fibers smaller than 500 micrometers. Smaller shrimp tended to have more ingested microplastics relative to their body weight. The study estimates that people who regularly eat these shrimp could be consuming hundreds of microplastic particles per year, highlighting the need for protective measures.

Microplastic occurrence in deep-sea fish species Alepocephalus bairdii and Coryphaenoides rupestris from the Porcupine Bank (North Atlantic)
Microplastics were found in two deep-sea fish species collected from the Porcupine Bank in the North Atlantic, with occurrence in Alepocephalus bairdii and Coryphaenoides rupestris confirming that plastic ingestion extends to deep-water environments far from human activity. The study highlights the need for broader assessment of microplastic exposure in commercially unexploited deep-sea fauna.
Does the microplastics ingestion patterns and polymer composition vary across the oceanic zones? A case study from the Indian coast
Researchers examined microplastic ingestion in 27 species of deep-sea fish from the Central Indian Ocean and found contamination in 19 of them, with PET being the most common polymer. The study suggests that feeding behavior, rather than habitat depth or trophic level, is the primary factor influencing how much microplastic deep-sea fish ingest, and proposes these fish could serve as indicators for monitoring deep-sea plastic pollution.
