Artisanal fishery activities support the livelihoods of millions of people worldwide, particularly in developing countries. Within these fisheries, distal global drivers can promote switching between alternative target resources. These drivers can promote the rapid development of new, unregulated and previously unexploited fisheries that pose a threat to the sustainability of ecosystems. In this paper, we describe a new artisanal shore gathering activity that targets a previously unexploited resource: the sandhopper (Orchestoidea tuberculata). The activity is driven by aquarium trade demand for food. We used mixed methods to describe the activity, assessed basic socio-economic incentives, and estimated Catches per Unit Effort. Results show that the sandhopper plays an important role for the livelihoods of shore gatherers engaged in the activity. Gatherers have adapted and developed two main extraction methods with different degrees of investment and extraction rates. Furthermore, gatherers have developed local knowledge regarding the ecology and management of the resource. Results show that economic incentives can motivate a rapid expansion of this unregulated activity. Future research gaps and management options to address the development of this fishery are discussed in light of these findings.
手工渔业活动为数百万计的人提供生计，特别是在发展中国家。在这些渔业中，遥远的全球驱动因素可以促进在替代目标资源之间进行切换。这些驱动因素可以促进新的、不受监管和以前未开发的渔业的快速发展，这些渔业对生态系统的可持续性构成威胁。在本文中，我们描述了一种新的手工岸钓活动，该活动以以前未开发的资源为目标：沙跳虾（Orchestoidea tuberculata）。该活动是由水族馆贸易对食物的需求驱动的。我们使用混合方法来描述该活动，评估基本的社会经济激励措施，并估计每单位努力的渔获量。结果表明，沙跳虾在从事该活动的岸钓者的生计中起着重要作用。采集者已经适应并开发了两种主要的提取方法，这些方法的投资和提取率不同。此外，采集者还积累了有关该资源生态和管理的本地知识。结果表明，经济激励可以促使这种不受监管的活动迅速扩张。根据这些发现，讨论了未来研究差距和管理选项，以解决该渔业的发展问题。
