Microplastic emissions from fishing ropes: Quantification, characteristics, and implications for marine pollution
Researchers quantified microplastics generated from the mechanical abrasion of polypropylene-based fishing ropes and found that over 92% of released particles were non-fiber fragments rather than fibers. Each additional kilogram of hauling weight produced roughly 1.4 extra microplastic particles per meter of rope. Global estimates suggest that fishing rope abrasion alone releases approximately 768 trillion microplastic particles annually, highlighting fishing gear as a substantial and often overlooked source of marine microplastic pollution.
Microplastics in Sediments Originating from Abandoned, Lost or Discarded Fishing Gear (ALDFG) in Coastal Areas of the Valencian Community
Abandoned, lost, or discarded fishing gear (ALDFG) is a pervasive problem in the Mediterranean, and this study directly measured its contribution to microplastic pollution in coastal sediments near Alicante and Benidorm, Spain. Sites with fishing nets on the seafloor had significantly higher microplastic concentrations than net-free control sites, with polymer types matching those used in fishing gear (nylon, polyethylene, polypropylene). The study provides direct evidence linking derelict fishing gear to localized microplastic hotspots, strengthening the scientific case for systematic retrieval programs and stricter regulations on gear loss in sensitive coastal areas.
