Abstract

Bycatch, the incidental catch of non-target species, threatens marine megafauna such as sea turtles and sea birds in the Mediterranean region. Identifying bycatch hotspots is essential to guide mitigation measures and target audiences. In the Mediterranean Sea, South Ionian Sea in Greece is a major marine habitat, including critical nesting areas, for sea turtles, and an important breeding and foraging habitat for sea birds. This work combined methodologies to identify bycatch hotspots through a vulnerability assessment and questionnaire surveys utilising both scientific data and local ecological knowledge (LEK). The study determined the major bycatch hotspots for sea turtles and sea birds, evaluated the potential impact on both species, and discussed mitigation measures to reduce the impact of bycatch and effectively protect this economically and ecologically important ecosystem. Our approach and outcomes may well contribute to a science-based and LEK included, adaptive management framework regarding the establishment or revision of Marine Protected Areas in the study area and elsewhere across critical marine habitats for sea turtles and sea birds.

结合关键栖息地和觅食区及其周围海洋巨型动物物种副渔获热点地区的检测方法

副渔获物，即偶然捕获的非目标物种，威胁着地中海地区的海龟和海鸟等海洋巨型动物。确定副渔获物热点对于指导缓解措施和目标受众至关重要。在地中海，希腊的南爱奥尼亚海是海龟的主要海洋栖息地，包括重要的筑巢区，也是海鸟的重要繁殖和觅食栖息地。这项工作结合了各种方法，通过脆弱性评估和利用科学数据和当地生态知识（LEK）的问卷调查来确定副渔获物热点。研究确定了海龟和海鸟的主要副渔获热点，评估了对这两个物种的潜在影响，并讨论了缓解措施，以减少副渔获的影响，有效保护这一经济和生态上重要的生态系统。我们的方法和结果很可能有助于在研究区域和其他海龟和海鸟的重要海洋栖息地建立或修订海洋保护区的科学基础和包括LEK在内的适应性管理框架。

期刊介绍： Marine Environmental Research publishes original research papers on chemical, physical, and biological interactions in the oceans and coastal waters. The journal serves as a forum for new information on biology, chemistry, and toxicology and syntheses that advance understanding of marine environmental processes. Submission of multidisciplinary studies is encouraged. Studies that utilize experimental approaches to clarify the roles of anthropogenic and natural causes of changes in marine ecosystems are especially welcome, as are those studies that represent new developments of a theoretical or conceptual aspect of marine science. All papers published in this journal are reviewed by qualified peers prior to acceptance and publication. Examples of topics considered to be appropriate for the journal include, but are not limited to, the following: – The extent, persistence, and consequences of change and the recovery from such change in natural marine systems – The biochemical, physiological, and ecological consequences of contaminants to marine organisms and ecosystems – The biogeochemistry of naturally occurring and anthropogenic substances – Models that describe and predict the above processes – Monitoring studies, to the extent that their results provide new information on functional processes – Methodological papers describing improved quantitative techniques for the marine sciences.
