Presence of microplastics in the stomachs of Carcinus aestuarii Nardo, 1857 in Çardak Lagoon, Çanakkale Strait, Turkey
AI summary Read the abstract
This study documented microplastic fibers in the stomachs of Mediterranean green crabs collected from a lagoon in Turkey, with plastic fibers found in crabs at multiple sampling sites — evidence that crustaceans in Turkish coastal waters are ingesting microplastics from their environment.
This paper reports the presence of microplastic in the stomachs of the Mediterranean green crab, Carcinus aestuarii Nardo, 1857. The crabs were collected from six sites chosen in the Çardak Lagoon (Çanakkale Strait). Plastic fibers were observed in the stomach contents of three male individuals. Since C. aestuarii is an important food for fish and birds in estuarine and lagoon areas, microplastics can go up to the trophic levels by entering the food chain.

Presence of Microplastics in Cronius Ruber Species
AI summary Read the abstract
Researchers examined microplastic content in the stomach contents of Cronius ruber, an invasive crab species in Mediterranean waters, finding plastic particles — primarily fibers — in the animals. The presence of microplastics in invasive crab species adds to the evidence that plastic ingestion is widespread across marine crustaceans in contaminated coastal waters.
The Ecological Implication of Microplastic in Crabs from a Tropical Lagoon: Ingested Microplastic in Mud Crab Scylla serrata
AI summary Read the abstract
Researchers examined microplastic ingestion by crabs from a tropical lagoon in West Africa, quantifying particles found in digestive tissues and assessing ecological implications for the local ecosystem. Widespread microplastic ingestion was documented across crab species and size classes.
Microplastics occurrence in gills and digestive tract tissues of blue crabs collected from the Persian Gulf coast
AI summary Read the abstract
Researchers documented microplastics in the gills and digestive tracts of blue crabs from coastal waters, finding MP particles of diverse types and sizes in both tissues and assessing implications for human health from consuming these commercially important crustaceans.
The Contamination of Microplastic Debris in Blue Swimming Crab Portunus pelagicus (Linnaeus, 1758) from Artisanal Fisheries in the Eastern Gulf of Thailand
AI summary Read the abstract
Researchers collected blue swimming crabs from the Gulf of Thailand and found microplastics in 62.5% of external body parts and 72.2% of internal parts, with fibers dominating and gut tissue showing the highest contamination. The findings indicate widespread MP ingestion in commercially harvested crabs and potential food safety implications.
Atlantic blue crab (Callinectes sapidus Rathbun, 1896): Microplastic pollution indicator in invaded Mediterranean coastal ecosystems
AI summary Read the abstract
Researchers used the invasive Atlantic blue crab as a microplastic sentinel in a Mediterranean lagoon, finding an average of 17 MPs per individual — dominated by polypropylene and polyethylene fragments in the 100–299 µm range — with the hepatopancreas accumulating the highest concentrations compared to muscle and gills.
