Anthropogenic marine litters or microplastics (MPs) accumulation in marine organisms is an emerging environmental threat. In this background, the gastrointestinal tract of Coilia dussumieri (n = 150) was studied in the samples collected from the fishing grounds of the north east coast of Arabian Sea through experimental fishing. Out of the total 150 specimens collected, all showed the incidence of microplastic particulates in the guts. The average abundance of MPs was found to be 6.98 ± 2.73 items/individual whereas gastrointestinal tract recorded with an average number of 28.84 ± 10.13 MPs/g in the gut material. The dominant MPs were found in the size range of 100-250 μm and of fibers type mostly blue in color. The prevalence of MPs in Coilia dussumieri is a matter of serious concern due to its ecological consequences due to trophic transfer in the connected food chains and probable threats to the health of human beings consuming the fish.
人为产生的海洋垃圾或微塑料（MPs）在海洋生物体内的积累是一种新出现的环境威胁。在此背景下，通过实验性捕捞，对从阿拉伯海东北海岸渔场采集的杜氏棱鳀（n = 150）样本的胃肠道进行了研究。在总共收集的150个标本中，所有标本的肠道中均发现有微塑料颗粒。发现微塑料的平均丰度为6.98 ± 2.73个/个体，而肠道物质中记录的胃肠道平均微塑料数量为28.84 ± 10.13个/克。主要的微塑料尺寸范围在100 - 250微米，且大多为蓝色纤维类型。杜氏棱鳀体内微塑料的普遍存在因其在相连食物链中的营养转移所带来的生态后果以及对食用该鱼类的人类健康可能造成的威胁而令人严重关切。
