Marine litter levels were measured in the stomach contents, hepatopancreas, and gonad tissues of crustacea decapod (Callinectes sapidus Rathbun, 1896; n = 6), a widespread alien species affecting the Lesina lagoon. Results highlight a mean of 2.5 (SD = 1.6) items/animal and indicate the presence of metals fragments (13%) and plastics (13% PE; 6.7% PET) in the stomach contents of collected individuals. No microplastic particles were detected in the hepatopancreas or in muscle tissue, while microplastic fibres (nylon, rayon, polyester) were found present in female specimen gonads. The presence of synthetic fibres in the investigated species reflects the relative contamination level in this habitat type and suggests that the blue crab could be considered a model organism for evaluating the contamination status of the study area.

测量了de足动物的胃内容物，肝胰脏和性腺组织中海洋垃圾的含量（Callinectes sapidus Rathbun，1896；n = 6），是影响莱斯纳泻湖的广泛外来物种。结果突出显示平均每只动物有2.5（SD = 1.6）个项目，并表明收集到的个体的胃中存在金属碎片（13％）和塑料（13％PE; 6.7％PET）。在肝胰腺或肌肉组织中未检测到微塑料颗粒，而在女性标本性腺中发现微塑料纤维（尼龙，人造丝，聚酯）。被调查物种中合成纤维的存在反映了该栖息地类型中的相对污染水平，这表明蓝蟹可以被视为用于评估研究区域污染状况的模型生物。
