Assessing the current and future sustainability of coral reef ornamental fisheries under different management scenarios.

许多种类的野生海洋观赏鱼和无脊椎动物是从热带珊瑚礁收集的，以供应国际海洋水族馆贸易。今天，估计有2300种鱼类和725种无脊椎动物在交易，其中大部分供应来自印度-太平洋地区，最终销往美国或欧洲。热带海洋渔业具有高度的生物多样性，但缺乏制定国家和国际政策所要求的有效管理协议所需的基础数据。观赏性渔业为来源国的当地社区提供了重要的生计，其货币(约200亿美元/年；King，2019年)和内在价值可用作保护当地珊瑚礁生态系统的激励措施。这一博士学位将建立和发展评估方法，促进小型观赏性珊瑚礁鱼的可持续捕捞，使生物多样性和依赖它们的社会经济系统受益。这项工作将使用预先存在的生活史参数而不是大小谱来完成，这是因为优先以小鱼和幼鱼种群人口统计为目标，并公布了范围数据(FishBase，FishTraits)。此外，来自印度尼西亚的一个案例研究现场的数据，在那里有渔获量的估计(例如，渔民的收据和所采集鱼类的发票)。还将制定在不同管理情景下预测渔业未来可持续性的建模方法。博士学位将有助于更好地了解海洋观赏渔业的种群状况和可持续性。

Many species of wild marine ornamental fish and invertebrates are collected from tropical coral reefs to supply the international marine aquarium trade. Today, an estimated 2300 species of fish and 725 species of invertebrates are traded, with most of the supply originating from the Indo-Pacific region and destined for final sale in the United States or Europe. Tropical marine fisheries are highly biodiverse, but lack the underlying data needed to develop effective management protocols called for in national and international policy. The ornamental fisheries provide important livelihood provisioning to local communities in source countries, and their monetary (~$20 bn /year; (King, 2019)) and inherent value can be used as an incentive to protect local reef ecosystems. This PhD will build and develop assessment methods that promote sustainable harvesting of small ornamental reef fish to benefit both biodiversity and the socio-economic systems that rely on them. This work will be completed using pre-existing life history parameters instead of size spectra, due to preferential targeting of small and juvenile fish skewing population demographics, and published range data (FishBase, FishTraits). In addition, data from a case study field location in Indonesia where estimates of catch (e.g., fishers' receipts and invoices of fish collected) are available. Modelling approaches to predict the future sustainability of fisheries under different management scenarios will also be developed. The PhD will contribute to better understanding of the population status and sustainability of marine ornamental fisheries.
