This paper analyses the measures adopted by Spain under national, European and international regulations, in the fight against illegal, unreported and unregulated (IUU) fishing. The paper explains how Spain, as a leading European and international fishing power, has been a pioneer in the adoption of said measures. The strategy put into action by Spain against this illicit activity is based on the effective exercise of its jurisdiction as a state, and the application of a broad, rigorous, and powerful sanctioning regime. In this regard, the article shows how the administrative sanctioning process has proved to be highly effective against IUU fishing offences and has demonstrated its deterrent power in the fight against illegal fishing. The article concludes that the reinforcement of coordination and collaboration mechanisms between states, is the best way forward to ensure the coherence and effectiveness of the regional, national and international legal framework, and to avoid loopholes in their implementation to prevent IUU fishing activities. To this end, the Regional Fisheries Management Organizations (RFMOs) play an extremely important role. The European Union, as a member of these organisations, should contribute through its initiatives, to the adoption of more decisive solutions against predatory fishing practices.

本文分析了西班牙根据国家、欧洲和国际法规在打击非法、不报告和不管制 (IUU) 捕鱼方面采取的措施。该文件解释了西班牙作为领先的欧洲和国际渔业大国，如何成为采取上述措施的先驱。西班牙针对这种非法活动采取的战略是基于其作为一个国家的有效行使管辖权，以及广泛、严格和强大的制裁制度的应用。在这方面，文章展示了行政制裁程序如何被证明对 IUU 捕捞违法行为非常有效，并在打击非法捕捞方面显示出其威慑力。文章的结论是，加强国家间的协调合作机制，是确保区域、国家和国际法律框架的连贯性和有效性并避免其实施中出现漏洞以防止 IUU 捕捞活动的最佳途径。为此，区域渔业管理组织（RFMO）发挥着极其重要的作用。作为这些组织的成员，欧盟应通过其倡议为采取更果断的解决方案来打击掠夺性捕捞行为做出贡献。
