| Abstract | Plastic pollution has increased globally and poses imminent risks to human health and marine life. This study assessed microplastic (MP) contamination in the gastrointestinal tract (GIT) of the commercial marine prawn Metapenaeus kutchensis from three major fishing centres in Gujarat. Samples were laboratory-dissected, and GIT was digested with 10% KOH. MPs were isolated using ZnCl⿿ density gradient separation, filtered, and observed under stereo microscopy. Physical and chemical characterisation determined total count, shape, size, and colour. From 135 individuals, 173 MPs were identified, showing 100% contamination. Average MP abundance was 3.94 ± 2.40 MPs per gram (range: 1.68 ± 0.87 to 5.40 ± 1.90 MPs/g). Post-monsoon periods showed highest contamination, followed by monsoon and pre-monsoon periods. MP contamination varied significantly between sites. Environmental MP abundance was 11.25 ± 12.23 MPs/kg in sediment and 1.38 ± 0.78 MPs/L in water. Regression analysis revealed no significant correlation between body length and MP abundance. Principal component analysis demonstrated varied environmental factors influencing prawn MP contamination. Blue and black fibers were most prevalent, with 1⿿2 mm size class predominating across all sites. Chemical analysis identified polyethylene, polyethylene terephthalate, and polypropylene compositions. This study of MP contamination in endemic species reveals pollution impacts on sensitive, unique organisms, supporting biodiversity conservation and ecosystem health awareness. The findings provide crucial baseline data for future research and inform management strategies for conserving Gujarat's marine ecosystems and safeguarding their health. |
