In spite of several policies to promote fisheries management in the Galapagos Marine Reserve (GMR), in the past there has been a collapse or near collapse of the two most important fisheries: the sea cucumber and the lobster fishery respectively. Currently, there is particular concern for the Galapagos Sailfin Grouper (Mycteroperca olfax), a regionally endemic species showing signs of severe decline and targeted by the white-fin fishery, a multi-species coastal fishery of high market value. Within this context, the Galapagos National Park Directorate (GNPD) and local NGOs have designed a policy consistent in a product certification scheme aiming to shift fishing efforts from depleted coastal fisheries to healthier pelagic stocks, whilst supporting artisanal fisher’s livelihoods. Using a discrete choice experiment and accompanying survey data, the goal of this research is to analyze the preferences and tradeoffs made by individuals across attributes when purchasing certified fish in the Galapagos. In particular, we account for pro-environmental attitudes within a WTP space model specification and estimate the expected price premiums that tourists would be willing to pay for yellowfin tuna in the area in light of specific characteristics of its local value chain. We find that tourists visiting the Galapagos hold pro environmental attitudes as measured by the New-ecological paradigm and that there is a considerable increase in consumer’s utility from a certification scheme. Tourists care about the level of bycatch associated with their consumption, food safety, quality, and whether is locally sourced, and would be willing to pay for these attributes. This evidence, driven by location specific characteristics of consumers and tourists, supports the design of market-based mechanisms for sustainable yellow fin tuna fisheries in the Galapagos

尽管有多项促进加拉帕戈斯海洋保护区 (GMR) 渔业管理的政策，但过去两个最重要的渔业：海参和龙虾渔业已经崩溃或接近崩溃。目前，人们特别关注加拉帕戈斯帆斑鱼（Mycteroperca olfax），这是一种区域特有物种，显示出严重衰退的迹象，是白鳍鱼渔业的目标，这是一种具有高市场价值的多物种沿海渔业。在此背景下，加拉帕戈斯国家公园管理局 (GNPD) 和当地非政府组织制定了与产品认证计划一致的政策，旨在将捕捞活动从枯竭的沿海渔业转移到更健康的远洋种群，同时支持手工渔民的生计。使用离散选择实验和随附的调查数据，本研究的目标是分析个人在加拉帕戈斯群岛购买经过认证的鱼类时对不同属性的偏好和权衡。特别是，我们在 WTP 空间模型规范中考虑了亲环境态度，并根据当地价值链的具体特征估计了游客愿意为该地区黄鳍金枪鱼支付的预期价格溢价。我们发现访问加拉帕戈斯群岛的游客持有新生态范式衡量的环保态度，并且从认证计划中消费者的效用显着增加。游客关心与他们的消费、食品安全、质量以及是否本地采购相关的兼捕水平，并愿意为这些属性付费。这个证据，
