Microplastic prevalence in epipelagic layer: Evidence from epipelagic inhabiting prawns of north-west Arabian Sea
AI summary Read the abstract
Researchers assessed microplastic contamination in ten commercial prawn species from the northwest Arabian Sea off Gujarat, India. The study found an average of 590 microplastic particles across gastrointestinal tracts, with significant variation between species and harbors, highlighting concerns about microplastic transfer through commercially important seafood.
The escalating global microplastic (MP) pollution severely threatens marine life due to insufficient waste management and widespread single-use plastic. This study focuses on assessing MP contamination in commercial prawns from Gujarat State, India. Ten prawn species collected at five main fishing harbors revealed 590 MP particles in their gastrointestinal tracts, averaging 6.08 ± 5.96 MPs/g and 1.15 ± 0.78 MPs/individual. Significant variations in contamination levels were observed between species and study sites. Pollution indices indicated very high contamination throughout the study sites. Threads were the predominant shape, with blue and black as prevalent colors. Size-wise, 1-2 mm MPs dominated. Polymer analysis identified polyethylene terephthalate, polyurethane, polystyrene, polypropylene, polyvinyl chloride, and acrylonitrile butadiene styrene. The findings provided crucial preliminary information for ecotoxicology and seafood safety investigations regarding MP contamination in commercially important prawns.

Microplastics in shrimps: a study from the trawling grounds of north eastern part of Arabian Sea
AI summary Read the abstract
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.
Occurrence and Characterization of Microplastics in the Gastrointestinal Tracts of Fish and a Crustacean from the Keralam Coast, Southeastern Arabian Sea
AI summary Read the abstract
Researchers found tiny plastic particles (microplastics) in the stomachs of nearly half of the fish and shrimp they tested from a fishing harbor in India, including popular seafood like mackerel and mullet. These plastics likely come from urban runoff and harbor activity, and since these are commercially sold species, this raises concern that the plastic we dump in the ocean could be making its way onto our dinner plates.
