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

从热带珊瑚礁采集许多野生海洋观赏鱼和无脊椎动物，以供应国际海洋水族馆贸易。今天，估计有2300种鱼类和725种无脊椎动物被交易，其中大部分供应来自印度-太平洋地区，最终在美国或欧洲进行销售。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规程所需的基本数据。观赏渔业为来源国的当地社区提供了重要的生计保障，其货币价值（约200亿美元/年;（King，2019））和内在价值可用作保护当地珊瑚礁生态系统的激励措施。该博士将建立和开发评估方法，促进小型观赏珊瑚鱼的可持续收获，以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，而不是大小谱完成，由于优先针对小型和幼鱼的人口统计数据和公布的范围数据（FishBase，FishTraits）。此外，来自印度尼西亚一个案例研究现场的数据显示，渔民收据及渔获收据）。还将制定模型方法，以预测在不同管理情景下渔业的未来可持续性。博士学位将有助于更好地了解海洋观赏渔业的人口状况和可持续性。

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.
