| contents | From sea to shore: Estimating used, lost and stranded fishing gear in the Southeastern Bay of Biscay through models and a novel gear identification key. Dusacre, Edgar González-Soto, Nagore Le Bihanic, Florane Galib, Asadulla Hil Boura, Chloé Fuertes, Idoia Ballesteros, Maria Moreno, Clément Lecomte, Sophie P Cajaraville, Miren Cachot, Jérôme Fisheries Environmental Monitoring Bays Plastics Water Pollutants, Chemical Microplastics Lost large pieces of fishing gear (FG) have well-documented impacts on marine ecosystems, yet the environmental risks of their degradation products remain poorly understood. Assessing these risks requires quantifying the microplastics, nanoplastics, and associated chemicals generated by different FG types. However, regional-scale data on FG used, lost, and beached are scarce. Using the Southeastern Bay of Biscay as a case study, we applied models to estimate the quantities of used and lost plastic FG. Additionally, eight beaches were sampled in four seasons during 2023. Fishing-related items were identified by FG origin using a novel identification key specifically developed for this purpose. Once fishing related items were identified by FG origins, their polymers were determined by ATR-FTIR. In total, we estimated that 211 tons of plastic FG were used and 6 tons were lost in 2023. Gillnets (2.7 tons), and longlines (2.5 tons), were the most frequently lost FG. Altogether, 7.6 % of items collected in the beaches were identified as coming from the fishing sector. Of these, 89.8 % of the items were mending pieces, 2.6 % were lines, and 2.5 % were longlines. In total, we estimated that 3 tons of FG were beached in the coastline during the studied period. Regarding polymer composition, polyethylene and polypropylene accounted for 95.1 % of the FG and polyamide for 3.3 %. This study presents a useful methodology and provides new data for the identification and quantification of used, lost, and beached plastic FG, contributing to future assessments of the environmental risk associated with their degradation products. |
