Unsustainable wildlife trade affects biodiversity and the livelihoods of communities dependent upon those resources. Wildlife farming has been proposed to promote sustainable trade, but characterizing markets and understanding consumer behavior remain neglected but essential steps in the design and evaluation of such operations. We used sea turtle trade in the Cayman Islands, where turtles have been farm raised for human consumption for almost 50 years, as a case study to explore consumer preferences toward wild-sourced (illegal) and farmed (legal) products and potential conservation implications. Combining methods innovatively (including indirect questioning and choice experiments), we conducted a nationwide trade assessment through in-person interviews from September to December 2014. Households were randomly selected using disproportionate stratified sampling, and responses were weighted based on district population size. We approached 597 individuals, of which 37 (6.2%) refused to participate. Although 30% of households had consumed turtle in the previous 12 months, the purchase and consumption of wild products was rare (e.g., 64-742 resident households consumed wild turtle meat [i.e., 0.3-3.5% of households] but represented a large threat to wild turtles in the area due to their reduced populations). Differences among groups of consumers were marked, as identified through choice experiments, and price and source of product played important roles in their decisions. Despite the long-term practice of farming turtles, 13.5% of consumers showed a strong preference for wild products, which demonstrates the limitations of wildlife farming as a single tool for sustainable wildlife trade. By using a combination of indirect questioning, choice experiments, and sales data to investigate demand for wildlife products, we obtained insights about consumer behavior that can be used to develop conservation-demand-focused initiatives. Lack of data from long-term social-ecological assessments hinders the evaluation of and learning from wildlife farming. This information is key to understanding under which conditions different interventions (e.g., bans, wildlife farming, social marketing) are likely to succeed.
不可持续的野生动植物贸易影响生物多样性和依赖这些资源的社区的生计。野生动物养殖被提议用于促进可持续贸易,但描述市场和了解消费者行为仍然是这种运营设计和评估中被忽视但必不可少的步骤。我们以开曼群岛的海龟贸易为例,研究了消费者对野生来源(非法)和养殖来源(合法)产品的偏好,以及潜在的保护影响。我们创新性地结合了各种方法(包括间接询问和选择实验),于 2014 年 9 月至 12 月通过个人访谈进行了全国性的贸易评估。通过不成比例的分层抽样随机选择家庭,根据地区人口规模对回答进行加权。我们共接触了 597 个人,其中 37 人(6.2%)拒绝参与。尽管 30%的家庭在过去 12 个月中食用过海龟,但野生产品的购买和食用仍然很少见(例如,64-742 户居民家庭食用野生海龟肉[即 0.3-3.5%的家庭],但由于野生海龟数量减少,对该地区的野生海龟构成了巨大威胁)。通过选择实验发现,消费者群体之间存在明显差异,产品的价格和来源对他们的决策起着重要作用。尽管长期以来一直有养殖海龟的做法,但仍有 13.5%的消费者表现出对野生产品的强烈偏好,这表明野生动物养殖作为可持续野生动物贸易的单一工具存在局限性。通过结合间接询问、选择实验和销售数据来调查对野生动物产品的需求,我们深入了解了消费者行为,可以将这些信息用于制定以保护需求为重点的倡议。缺乏长期社会生态评估的数据,阻碍了对野生动物养殖的评估和从中学习。这些信息是了解在哪些条件下不同干预措施(例如,禁令、野生动物养殖、社会营销)可能成功的关键。
