1. Marine mammals are indicators of ecosystem health, and thus stranding records are an invaluable information source. The response to marine mammal stranding (RMMS) must be comprehensive, taking into account three components: (i) operations, (ii) research, and (iii) information dissemination. Although RMMS had previously been practised in several coastal locations in Mexico, the recent enforcement of a new regulation for RMMS has posed a challenge to actors as they adapt to it.
2. To understand the functioning of RMMS in Mexico, Bahía Todos Santos and Bahía de La Paz, two localities with over 20 years of experience in RMMS, were selected. To achieve this goal, a document review to identify the actors involved and their functions was undertaken together with a social network analysis to identify relevant actors in each locality and semi‐structured interviews to identify key topics for RMMS.
3. The composition of the involved actors was similar at both locations. Some actors were found to have mandatory functions (i.e. governmental actors), while others (i.e. civil society organizations) performed functions beyond those established in official documents. Governmental agencies, the academic sector, and civil society organizations were the most connected actors and could help disseminate information, facilitate communication within the network, and influence decision‐making.
4. The main topics identified were, in order of relevance: (i) economic constraints; (ii) actors' involvement; (iii) stranding response logistics; and (iv) recognition among actors.
5. In conclusion, several limitations to the RMMS exist at both localities, mainly related to the lack of economic resources, but actors involved in RMMS actions are motivated by their own interests. This study proposes the integration of actors into local networks that take into consideration the biological, physical, and social characteristics of each place.

墨西哥海洋哺乳动物搁浅的反应：经验教训

1. 海洋哺乳动物是生态系统健康的指标，因此搁浅记录是宝贵的信息来源。对海洋哺乳动物搁浅（RMMS）的响应必须综合考虑三个组成部分：（i）操作，（ii）研究和（iii）信息传播。尽管RMMS以前曾在墨西哥的几个沿海地区实施过，但最近对RMMS实施新法规的实施给行为体适应挑战提出了挑战。
2. 为了了解RMMS在墨西哥的功能，我们选择了两个拥有20多年RMMS经验的地区的巴伊亚托多斯桑托斯（BahíaTodos Santos）和巴伊亚德拉巴斯（Bahíade La Paz）。为了实现这一目标，进行了一次文档审查，以确定参与人员及其职能，并进行了社交网络分析，以识别每个地区的相关参与者，并进行了半结构化访谈，以识别RMMS的关键主题。
3. 参与活动的演员在两个地方的组成都是相似的。发现有些行为者具有强制性职能（即政府行为者），而其他行为者（即民间社会组织）所履行的职能超出了正式文件中规定的职能。政府机构，学术部门和民间社会组织是联系最紧密的参与者，可以帮助传播信息，促进网络内部的沟通并影响决策。
4. 按相关性顺序，确定的主要主题是：（i）经济限制；（ii）演员的参与；（iii）搁置响应物流；（iv）演员之间的认可。
5. 总之，两个地方对RMMS都存在一些局限性，主要与缺乏经济资源有关，但是参与RMMS行动的参与者是出于自身利益的动机。这项研究建议将参与者整合到本地网络中，并考虑到每个地方的生物，物理和社会特征。
