This study focuses on the necessary elements to implement strategic mitigation in order to avoid Cuvier's beaked whale (CBW) strandings linked to intense sound sources, such as military active sonars, in the Mediterranean Sea. A careful review of stranding data and the analysis of existing survey results are required to highlight the main characters of the species regional distribution. Focused and repeated surveys are needed to confirm that possible favourable areas, such as the Balearic, Tyrrhenian or Aegean Seas, are really favourable CBW habitats. These surveys should be carried out with sea states 0 to 1 in order to minimize the risk of false absence data. Among the regions of interest, the central Tyrrhenian Sea was surveyed with a 12 m sailboat in 2007 and 2008. With 907 km of effective effort, a mean sighting rate of 1.9 CBW school/100 km was obtained, which is amongst the highest densities recorded in the Mediterranean.
本研究重点关注在避免地中海中与高强度声源（如军事主动声纳）相关的库氏喙鲸（CBW）搁浅所需的必要因素。需要仔细审查搁浅数据并分析现有调查结果，以突出该物种区域分布的主要特征。需要进行集中和重复调查，以确认可能的有利区域，如巴利阿里群岛、第勒尼安海或爱琴海，是否真的是 CBW 的有利栖息地。这些调查应在海况 0 至 1 时进行，以最大程度地降低虚假缺失数据的风险。在相关区域中，2007 年和 2008 年使用 12 米帆船对中第勒尼安海进行了调查。在 907 公里的有效努力下，获得了每 100 公里 1.9 群 CBW 的平均目击率，这是在地中海记录到的最高密度之一。
