Abandoned, lost, or otherwise discarded fishing gear (ALDFG) is considered a problem of global concern which can cause considerable negative environmental and socioeconomic consequences. Due to use slowly degrading plastic materials in construction, ALDFG remain marine environment for decades. Enclosed environments are particularly vulnerable all types pollution anthropogenic effects, including resulting from ALDFG. However, the extent this often not estimated. We estimated level accumulated semi-enclosed coastal Gulf Riga along areas Baltic Sea susceptible different pollution, based our results on pragmatic approach using existing estimates. The showed potentially amount derelict over last decade, specifically gillnets entangling nets trap (2762 netting sheets (CI: 969–4976) 1379 lost traps 473–2337)). Therefore, study highlights need fisheries management implement adequate monitoring mechanisms subsequent clean-up operations limit continuous ghost fishing.

An index to differentiate megafauna entangled in operational fishing gears from abandoned, lost, or otherwise discarded fishing gears

The Science of The Total Environment, Год журнала: 2025, Номер 971, С. 178950 - 178950

Classifying entanglements of marine megafauna in certain anthropogenic items is challenging because many are found fishing-related items, with the cause being either operational fishing gear (OFG) or abandoned, lost, otherwise discarded (ALDFG). The distinction between OFG and ALDFG essential as each source requires different mitigation remediation strategies. To reduce uncertainty sorting these two distinct threats, we developed Entanglement Source Assessment (ENSA) index. This index integrates a series criteria related to entangling item affected organism. It assess likelihood that an entanglement was caused by using Multi-Criteria Decision Analysis approach. tested on 35 events involving various taxa, video footage photographs recorded Azores Archipelago (NE Atlantic). Overall, 57 % were classified likely (ENSA scoring >60), indicating they resulted from debris. In comparison, 23 interactions ≤40). remaining ambiguous could not be confidently assigned source. ENSA valuable tool expert knowledge, transparently providing clear view steps reasoning behind classification process. will promote standardization when reporting (OFG vs. ALDFG), which for implementing adequate policy measures address at national global scales.

Derelict fishing gear in relation to the characteristics of coastal fisheries in Taiwan

ICES Journal of Marine Science, Год журнала: 2025, Номер 82(4)

Опубликована: Апрель 1, 2025

Abstract Taiwan’s fishing industry is characterized by abundant marine resources and diverse operation modes. However, significant investment in activities has also led to substantial fishing-related waste. This study analyzed 1037 beach cleanup records collected from 2009 2018 across various counties cities Taiwan, focusing on the composition distribution hotspots of debris derelict gear (DFG). The results identified Kaohsiung, Hsinchu, Taichung, Tainan, Keelung—counties located northern western Taiwan—as top five regions with highest quantities debris. Among DFG, floating items were most prevalent (59%), followed (25%) tackle (16%). further revealed that influential factors for all three DFG types average tonnage boats boat number net type (N). quantity reflect specific characteristics each county, such as usage, aquaculture activities, consumer demand products. These findings provide valuable insights into primary their underlying causes different regions, offering a foundational basis development targeted governmental policies address management Taiwan.

An Integrated Approach to Assessing the Potential of Plastic Fishing Gear to Release Microplastics

Water, Год журнала: 2025, Номер 17(10), С. 1439 - 1439

Опубликована: Май 10, 2025

Abandoned, lost, or discarded fishing gear (ALDFG) poses significant environmental threats, namely contributing to microplastic (MP) pollution. However, the release of MPs from ALDFG remains poorly studied, despite its crucial role in understanding plastic pollution marine ecosystems. This study is, best our knowledge, first assess impact as a source MPs, using an integrated approach combining laboratory experiments, situ field trials, and surveys. Laboratory tests showed that presence light sediment, braided polyethylene net released 1 fibre after incubation, demonstrating studied nets had potential MPs. In experiments semi-enclosed environment did not show clear influence submerged on water due high MP contamination selected location (5322 ± 4936 m−3). Nonetheless, at hotspots off northwest Portugal, increased samples compared locations without suggested release. These findings demonstrate act showcase need for further studies, order comprehensively investigate degradation different field. Reducing is critical mitigating preserving

Hydrogen Production from Fishing Net Waste for Sustainable Clean Fuel: Techno-Economic Analysis and Life Cycle Assessment

Опубликована: Янв. 1, 2023

Fishing net waste (FNW) represents more than half of marine debris, posing a substantial challenge to ecosystems. Conventional disposal methods, such as landfills and incineration, contribute environmental pollution overlook valuable material recovery. To tackle this issue, we propose an innovative process converting FNWs into high-purity hydrogen (H2) through pyrolysis under CO2 conditions, integrated with natural gas (NG) reforming process. The resulting undergoes water-gas shift (WGS) reaction NG-reforming syngas, amplifying H2 production yield. High-purity is achieved pressure swing adsorption (PSA). high-temperature flue from oil combustion utilized generate electricity via the steam Rankine cycle (SRC) Furthermore, in liquefied stored carbon capture storage (CCS) Techno-economic evaluation life-cycle assessment (LCA) were performed scrutinize efficiency feasibility proposed This study demonstrated generation 10.66 kmol h-1 fishing process, providing significant step toward sustainable production. Process energy optimization recovered 87.13% wasted energy, additional 539.1 kW power was generated by SRC indicating high efficiency. Although levelized cost (LCOH) slightly higher that methane (SMR) LCA revealed significantly lower greenhouse (GHG) index. Therefore, suggested provides eco-friendly approach for producing clean H2, concurrently addressing recycling FNWs.
