Abstract

IntroductionPlastic pollution at sea is a critical global issue, but despite legislative requirements, scant information is available for the ongoing assessment of this threat. Abandoned, lost, or otherwise discarded fishing gear (ALDFG) significantly contributes to marine litter, ghost fishing, and ecosystem degradation.MethodsA multidisciplinary research effort, carried out in collaboration with small-scale fishers, introduced a new methodological approach implementing sustainable and biodegradable fishing gear. This approach combined experimental field trials with performance monitoring to test pot nets lined with biodegradable and compostable material prototypes, used in artisanal fisheries targeting Plesionika edwardsii.ResultsAccording to our results, these alternative materials deliver artisanal performance comparable to that of traditional plastics, including fishing efficacy, while reducing environmental impact.Discussion/ConclusionEarly-stage trials indicate that biodegradable pots, while requiring further refinement for effective use in fishing, represent a viable option for reducing ghost fishing and plastic pollution, supporting biodiversity conservation. This work demonstrates a replicable framework for testing and validating sustainable fishing gear under real-world conditions, supporting evidence-based decisions in marine resource management.

小型爱德华型Plesionika渔业可持续渔具评价的实地框架

海洋塑料污染是一个重要的全球性问题，但尽管有立法要求，对这一威胁进行持续评估的信息却很少。被遗弃、丢失或以其他方式丢弃的渔具（ALDFG）对海洋垃圾、幽灵捕鱼和生态系统退化起着重要作用。方法与小规模渔民合作开展的一项多学科研究工作介绍了一种实施可持续和可生物降解渔具的新方法。该方法将试验性田间试验与性能监测相结合，测试内衬生物可降解和可堆肥材料原型的锅网，用于针对Plesionika edwardsii的手工渔业。根据我们的研究结果，这些替代材料提供了与传统塑料相当的手工性能，包括捕鱼功效，同时减少了对环境的影响。早期试验表明，可生物降解罐是减少幽灵捕鱼和塑料污染、支持生物多样性保护的可行选择，但需要进一步改进才能有效地用于捕鱼。这项工作展示了一个可复制的框架，用于在现实条件下测试和验证可持续渔具，支持海洋资源管理中的循证决策。

期刊介绍： Frontiers in Marine Science publishes rigorously peer-reviewed research that advances our understanding of all aspects of the environment, biology, ecosystem functioning and human interactions with the oceans. Field Chief Editor Carlos M. Duarte at King Abdullah University of Science and Technology Thuwal is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, policy makers and the public worldwide. With the human population predicted to reach 9 billion people by 2050, it is clear that traditional land resources will not suffice to meet the demand for food or energy, required to support high-quality livelihoods. As a result, the oceans are emerging as a source of untapped assets, with new innovative industries, such as aquaculture, marine biotechnology, marine energy and deep-sea mining growing rapidly under a new era characterized by rapid growth of a blue, ocean-based economy. The sustainability of the blue economy is closely dependent on our knowledge about how to mitigate the impacts of the multiple pressures on the ocean ecosystem associated with the increased scale and diversification of industry operations in the ocean and global human pressures on the environment. Therefore, Frontiers in Marine Science particularly welcomes the communication of research outcomes addressing ocean-based solutions for the emerging challenges, including improved forecasting and observational capacities, understanding biodiversity and ecosystem problems, locally and globally, effective management strategies to maintain ocean health, and an improved capacity to sustainably derive resources from the oceans.
