Data‐limited fisheries assessment methods have great potential to help inform small island communities on the status of their fisheries resources. In this paper, we provide a length‐based assessment of an artisanal fishery that primarily targets spawning aggregations of Shortjaw Bonefish Albula glossodonta at Anaa Atoll in the Tuamotu Archipelago of French Polynesia. We assessed the length‐frequency distribution of the spawning stock across a 3‐year period (2016–2018). During this time, male and female Shortjaw Bonefish were fully recruited to the fishery at age 4 and age 5, respectively. Fishing mortality was over two times the range of natural mortality for this species (i.e., 0.21–0.32), and based on these estimates of natural mortality, the annual spawning potential ratio of the population was between 7% and 20% across the sampling years. The majority of the catch was sexually mature, with 78, 95, and 95% of the annual female catch in 2016, 2017, and 2018, respectively, being equal to or greater than the length of first maturity (i.e., 48 cm FL). However, every fisheries indicator and biological reference point suggested that the fishery was overexploited and in need of management intervention. To this aim, the community of Anaa (1) established an Educational Managed Marine Area, which overlaps with the Shortjaw Bonefish migratory corridor adjacent to Tukuhora village and (2) instated a temporal rahui (a traditional conservation method) inside the Educational Managed Marine Area during the peak months of the spawning season.

基于长度的南太平洋手工藻类渔业的评估：一种数据受限的管理和保护方法

数据有限的渔业评估方法具有很大的潜力，可以帮助向小岛屿社区介绍其渔业资源的状况。在本文中，我们提供了一个手工渔业是主要针对狐鳁的产卵聚集的基于长度的评估阿尔布拉glossodonta在法属波利尼西亚图阿莫图群岛的阿纳环礁。我们评估了三年（2016-2018）期间产卵种群的长度-频率分布。在此期间，雄性和雌性短颚骨鱼分别在4岁和5岁时被完全捕捞。捕捞死亡率是该物种自然死亡率范围的两倍以上（即0.21-0.32），并且根据这些自然死亡率的估计，整个采样年中种群的年产卵率在7％至20％之间。大部分渔获物是性成熟的，分别在2016、2017和2018年分别占年度雌性渔获量的78％，95％和95％，等​​于或大于第一次成熟的长度（即48 cm FL） 。然而，每个渔业指标和生物学参考点都表明渔业被过度开发，需要管理干预。为此，Anaa社区（1）建立了一个教育管理的海洋区域，该区域与毗邻Tukuhora村的Shortjaw Bonefish迁徙走廊重叠，并且（2）在该教育管理的海洋区域内恢复了暂时的rahui（传统保护方法）在产卵旺季。
