Teleost fish that form predictable spawning aggregations and undertake reproductive migrations can be particularly vulnerable to overexploitation. To support community-based management of an artisanal fishery that targets bonefish (Albula glossodonta) spawning aggregations, we used a combination of acoustic telemetry, biological sampling, and remote imagery to reveal the spatiotemporal spawning migrations of bonefish on Anaa Atoll in the Tuamotu Archipelago, French Polynesia. The spawning migrations of bonefish tracked with acoustic telemetry were restricted to the northern section of the atoll, with 99.6% of all detections at offshore spawning habitats occurring on fixed acoustic receivers adjacent to the atoll’s artisanal fish trap complex. Male bonefish undertook spawning migrations more frequently than females and these spawning migrations were common during the Austral winter and fall. The movements of bonefish spawning aggregations coincided with the lunar cycle, as a network analysis revealed an increase in network size and the diversity of habitat use within our acoustic array throughout the duration of the waning moon. Our results highlighted the need for the management of the artisanal trap fishery to prevent the overharvest of bonefish during their peak spawning periods. In response to the spatiotemporal management recommendations derived from this research, the local government established an Educational Managed Marine Area that includes the atoll’s bonefish spawning migratory corridor adjacent to Tukuhora village and a Rahui (i.e., seasonal closure) to improve the sustainability of the fishery.

热带太平洋被开发的 Albulid 的产卵迁移：对保护和基于社区的管理的影响

形成可预测的产卵聚集体并进行繁殖迁移的硬骨鱼特别容易受到过度开发的影响。为了支持以社区为基础的手工渔业管理，以骨鱼（Albula glassodonta）产卵聚集体为目标，我们结合使用声学遥测、生物采样和远程图像来揭示土阿莫土群岛阿纳环礁上骨鱼的时空产卵迁移，法属波利尼西亚。用声学遥测技术跟踪的骨鱼产卵迁徙仅限于环礁的北部，在离岸产卵栖息地的所有检测中，有 99.6% 发生在环礁手工捕鱼装置附近的固定声学接收器上。雄性骨鱼比雌性更频繁地进行产卵迁徙，这些产卵迁徙在南方冬季和秋季很常见。骨鱼产卵聚集体的运动与月球周期相吻合，因为网络分析显示，在整个亏月期间，我们的声学阵列中网络规模和栖息地使用的多样性都有所增加。我们的研究结果强调了管理手工捕捞渔业的必要性，以防止在产卵高峰期对硬骨鱼进行过度捕捞。为了响应从这项研究中得出的时空管理建议，当地政府建立了一个教育管理的海洋区，其中包括与 Tukuhora 村和 Rahui 相邻的环礁的骨鱼产卵洄游走廊（即，
