This article examines the development of marine tenure in the Maullín River, Chile. It starts with the emergence of artisanal red algae (Gracilaria chilensis) gathering and the changes resulting from the governmental ad hoc allocation of small-scale aquaculture concessions. We aim to track this transition, its drivers, effects on the work organization, gender relations, market relations and the sustainability/equity challenges currently confronting the community. We use a feminist political ecology approach to direct our multi-method data collection strategy and to analyse the empirical material. The State by enabling local tenure for the development of marine aquaculture concessions played an influential role in Maullín community attaining de facto territorial tenure. This led to the establishment of residential aquaculture communities while facilitating the integration of women in aquaculture activities. We see both steps as positive economic and social development opportunities in Maullín. While marine tenure has provided livelihood chances, low prices caused by the producers’ disadvantaged market position and the lack of supportive alliance building pose ongoing problems. We conclude that these factors are serious challenges to the sustainability of aquacultural livelihoods at Maullín River. While the case depicts aspects of women’s empowerment such as their engagement in developing potential post-production innovation ideas, entrepreneurial abilities to conduct market transactions as well as their better competence in literacy, math and financial expertise, there is still a long way to reach gender equality in the male-dominated aquacultural sector.

本文探讨了智利莫林河海洋保有权的发展。首先是手工红藻（Gracilaria chilensis）采集的出现以及政府临时分配小规模水产养殖特许权所带来的变化。我们的目标是追踪这一转变、其驱动因素、对工作组织的影响、性别关系、市场关系以及社区当前面临的可持续性/公平挑战。我们使用女权主义政治生态学方法来指导我们的多方法数据收集策略并分析经验材料。国家通过允许地方使用权发展海水养殖特许权，在毛林社区获得事实上的领土使用权方面发挥了重要作用。这导致了住宅水产养殖社区的建立，同时促进妇女融入水产养殖活动。我们认为这两个步骤都是毛林积极的经济和社会发展机会。虽然海洋保有权提供了生计机会，但由于生产者的不利市场地位和缺乏支持性联盟建设而造成的低价造成了持续存在的问题。我们的结论是，这些因素对毛林河水产养殖生计的可持续性构成了严重挑战。虽然该案例描述了妇女赋权的各个方面，例如她们参与开发潜在的后期制作创新想法、进行市场交易的创业能力以及她们在识字、数学和金融专业知识方面的更好能力，但要实现性别平等还有很长的路要走男性主导的水产养殖部门的平等。
