This study represents the baseline of estimation of the potential service provided by fishermen as "cleaners of the sea". The amount, composition and depth distribution of marine litter in fishing grounds of the Northern Adriatic seafloor has been investigated through the fishing for litter (FFL) scheme. Passive FFL campaigns were carried out by trawlers from two of the most important fishing ports in the northern Adriatic, Chioggia and Goro, from May 2020 to May 2021. Over the course of 256 days of fishing, over 6 tons of litter were removed from 265 km of seafloor. Abandoned, lost and derelict fishing gears (ALDFG) were the most represented litter category (48 % of the total litter), and of these 67 % were plastic ALDFG (mostly mussel socks and fishing nets). Fouling on plastic waste was analyzed to determine the fraction of collected litter items that could be destinated to recycling. Only a small percentage of the plastic litter analyzed was "clean" from adherent and/or encrusting organisms. Approximately 2.4 tons of plastic were recovered, but, due to the biological colonization of surfaces, they cannot be recycled by using the technologies present in the area.
本研究代表了对渔民作为“海洋清洁者”所提供的潜在服务进行评估的基线。通过捕捞垃圾（FFL）计划，调查了北亚得里亚海海底渔场中海洋垃圾的数量、组成和深度分布。2020 年 5 月至 2021 年 5 月，来自北亚得里亚海两个最重要渔港——基奥贾和戈罗的拖网渔船进行了被动 FFL 活动。在 256 天的捕捞过程中，从 265 公里的海底清除了超过 6 吨的垃圾。废弃、丢失和废弃的渔具（ALDFG）是最具代表性的垃圾类别（占总垃圾的 48%），其中 67%是塑料 ALDFG（主要是贻贝袜和渔网）。分析了塑料废物上的污垢，以确定可回收的收集垃圾物品的比例。从附着和/或结壳生物中“清洁”出来的塑料垃圾比例很小。大约回收了 2.4 吨塑料，但由于表面的生物殖民化，它们不能通过使用该地区现有的技术进行回收。
