The Pacific sardine fishery is the most important in terms of catch volume in Mexico. Due to their trophic position, small pelagic fishes respond rapidly and abruptly to ocean climate variability at interannual (ENSO) and decadal time scales (PDO), which is why their response to climate change is expected. The present study applied the Rapid Vulnerability Assessment (RVA) designed for Natural Protected Areas to the context of sardine fishery in northwestern Mexico, expecting that the vulnerability of the fishery to climate change will be the same in the two main fishing areas. The results demonstrate that the RVA is a useful and lissome method, integrating all stakeholders knowledge, including the academic perspective, and serves as an adaptive strategic planning tool upon climate change. Also, because of its dynamics, it was shown to promote co management practices due to the collaborative consensus reached. The sardine fishery from the Gulf of California was considered as the most vulnerable to climate change due to the potential exchange of tropical species of lower commercial value; while environmental changes are expected to favor such fishery in the Pacific along Baja California peninsula. We recommend working on adaptation measures to lower the risk presented by overfishing, and address efforts towards the certification of the fishery in the Pacific region.

太平洋沙丁鱼渔业在墨西哥的捕捞量方面是最重要的。由于它们的营养位置，小型中上层鱼类对年际 (ENSO) 和年代际时间尺度 (PDO) 的海洋气候变化做出快速而突然的反应，这就是为什么它们对气候变化的反应是值得期待的。本研究将针对自然保护区设计的快速脆弱性评估（RVA）应用于墨西哥西北部的沙丁鱼渔业，预计渔业对气候变化的脆弱性在两个主要捕捞区是相同的。结果表明，RVA 是一种有用且简洁的方法，它整合了所有利益相关者的知识，包括学术观点，并可作为气候变化的适应性战略规划工具。此外，由于其动态性，由于达成的协作共识，它被证明可以促进共同管理实践。由于商业价值较低的热带物种的潜在交换，加利福尼亚湾的沙丁鱼渔业被认为最容易受到气候变化的影响；而环境变化预计将有利于下加利福尼亚半岛沿岸的此类渔业。我们建议制定适应措施以降低过度捕捞带来的风险，并致力于太平洋地区渔业认证。而环境变化预计将有利于下加利福尼亚半岛沿岸的此类渔业。我们建议制定适应措施以降低过度捕捞带来的风险，并致力于太平洋地区渔业认证。而环境变化预计将有利于下加利福尼亚半岛沿岸的此类渔业。我们建议制定适应措施以降低过度捕捞带来的风险，并致力于太平洋地区渔业认证。
