  1. The short‐beaked common dolphin is one of the most numerous cetacean species in the North‐East Atlantic and plays a key functional role within the ecosystem as a top predator. However, in 2013, its conservation status for the European Marine Atlantic, under Article 17 of the Habitats Directive, was assessed as ‘Unfavourable‐Inadequate’. Of key concern for this species is fishery bycatch, with pollution also being an issue. There are, however, major knowledge gaps concerning the extent of the effects of such pressures on the species.
  2. Implementation of national observer bycatch programmes and bycatch mitigation measures under EC Regulation 812/2004 has been important. The responsibility for this is currently being transferred to the EU fisheries Data Collection Framework and Technical Measures Framework, the potential advantages and disadvantages of which are discussed. Collection of data and samples through national stranding schemes in some countries has enabled assessments of life‐history parameters, dietary requirements, and the effects of stressors such as pollutants.
  3. Nevertheless, in order to improve the conservation status of the North‐East Atlantic population, a number of key actions are still required. These include the implementation of a species action plan, finalization of a management framework procedure for bycatch, and coordination between member states of monitoring programmes. It is important that there is monitoring of the state of the common dolphin population in the North‐East Atlantic management unit through regular surveys spanning the range of the management unit, as well as continued assessment of the independent and interactive effects of multiple stressors. Above all, conservation status would be improved through application and enforcement of existing legislation in European waters.
  4. This paper provides a summary of the current state of our knowledge of common dolphins in the North‐East Atlantic along with recommendations for conservation management that may also be relevant to the species in the Mediterranean Sea.

常见海豚的保护管理:从东北大西洋中学到的经验教训

  1. 短喙普通海豚是东北大西洋中数量最多的鲸类物种之一,在生态系统中作为顶级捕食者发挥着关键作用。但是,在2013年,根据《人居指令》第17条,其在欧洲海洋大西洋的保护状态被评为“不利-不足”。该物种最关注的是渔业兼捕,污染也是一个问题。但是,有关这种压力对物种的影响程度存在重大知识空白。
  2. 根据EC 812/2004法规实施国家观察员兼捕计划和缓解兼捕措施非常重要。目前,这方面的责任已转移到欧盟渔业数据收集框架和技术措施框架,并讨论了其潜在的优缺点。在一些国家中,通过国家搁浅计划收集数据和样本,使人们能够评估生活史参数,饮食需求以及压力源(如污染物)的影响。
  3. 然而,为了改善东北大西洋人口的保护状况,仍然需要采取一些关键行动。这些措施包括实施物种行动计划,最终确定兼捕的管理框架程序以及在监测计划的成员国之间进行协调。重要的是,应通过跨管理单位范围的定期调查来监视东北大西洋管理单位中海豚的种群状况,并持续评估多种压力源的独立和互动影响。最重要的是,可以通过在欧洲水域实施和执行现有法律来改善保护状况。
  4. 本文概述了我们对东北大西洋常见海豚的了解现状,并提出了与地中海物种有关的保护管理建议。
