Coupled Socio-Ecological Systems (SES) are frequent in the sea where several human activities coexist in a common space, maintaining individual attributes, but also creating inherent characteristics of this spatiotemporal coupling. The governance system, which minimises conflicts through maximizing agreements, offers an opportunity to achieve a balance between sectoral agendas. Establishing effective governance is challenging in the Southern Gulf of Mexico, where the new Energetic Reform (2013) has stressed the historically fragile equilibrium between fisheries and the oil industry. Through a Social Network Analysis (SNA), this work aims to identify the governance network directly involved in the decision-making process over the fishing-oil Socio-Ecological System (FOSES) of the coast of Tabasco. The mapping of 53 key actors (classified in eight functional groups) shows that the cohesion between them is low compared to the number of maximum relationships that could be established in the network. The distribution of the actors can be appreciated in three governance agendas. The energy agenda is ruled by the state oil company (PEMEX) and the Mexican Navy, while the social-fishing and intermediary environmental agendas are dominated by the fishing sector and the state environmental protection agency, respectively.

耦合的社会生态系统（SES）在海洋中很常见，在这里，几种人类活动共存于一个共同的空间中，既保持了各自的属性，又创造了这种时空耦合的固有特征。通过最大化协议来最大程度地减少冲突的治理系统为在部门议程之间取得平衡提供了机会。在墨西哥南部海湾，建立有效的治理具有挑战性，新的能源改革（2013年）在这里强调了渔业与石油工业之间历史上脆弱的平衡。通过社会网络分析（SNA），这项工作旨在确定直接参与塔巴斯科州海岸渔油社会生态系统（FOSES）决策过程的治理网络。53个关键角色（分为八个功能组）的映射显示，与网络中可以建立的最大关系数量相比，它们之间的凝聚力较低。可以在三个治理议程中了解参与者的分布。能源议程由国家石油公司（PEMEX）和墨西哥海军制定，而社会捕鱼和中间环境议程则分别由渔业部门和州环境保护局主导。
