| description | The optimal design of reserve networks and fisheries closures depends on species occurrence information and knowledge of how anthropogenic impacts interact with the species concerned. However, challenges in surveying mobile and cryptic species over adequate spatial and temporal scales can mask the importance of particular habitats, leading to uncertainty about which areas to protect to optimize conservation efforts. We investigated how telemetry-derived locations can help guide the scale and timing of fisheries closures with the aim of reducing threatened species bycatch. Forty juvenile speartooth sharks (Glyphis glyphis) were monitored over 22 months with implanted acoustic transmitters and an array of hydrophone receivers. Using the decision-support tool Marxan, we formulated a permanent fisheries closure that prioritized areas used more frequently by tagged sharks and considered areas perceived as having high value to fisheries. To explore how the size of the permanent closure compared with an alternative set of time-area closures (i.e., where different areas were closed to fishing at different times of year), we used a cluster analysis to group months that had similar arrangements of selected planning units (informed by shark movements during that month) into 2 time-area closures. Sharks were consistent in their timing and direction of migratory movements, but the number of tagged sharks made a big difference in the placement of the permanent closure; 30 individuals were needed to capture behavioral heterogeneity. The dry-season (May–January) and wet-season (February–April) time-area closures opened 20% and 25% more planning units to fishing, respectively, compared with the permanent closure with boundaries fixed in space and time. Our results show that telemetry has the potential to inform and improve spatial management of mobile species and that the temporal component of tracking data can be incorporated into prioritizations to reduce possible impacts of spatial closures on established fisheries.

Para explorar cómo el tamaño del cierre permanente se comparaba con un conjunto de cierres con áreas y tiempos alternativos (es decir, donde las áreas se cerraron a la pesca en diferentes momentos del año) usamos un análisis de clúster para agrupar los meses que tuvieron arreglos similares a las unidades de planeación seleccionadas (informadas por el movimiento de los tiburones durante ese mes) en dos cierres de tiempo-área. Los tiburones fueron consistentes en el tiempo y dirección de sus movimientos migratorios, pero el número de tiburones marcados generóunagran diferencia en la ubicación del cierre permanente; se necesitaron 30 individuos para capturar la heterogeneidad del comportamiento. Los cierres de tiempo-área de la temporada de secas (mayo–enero) y la de lluvias (febrero–abril) abrieron a la pesca un 20% y 25% más de unidades de planeación, respectivamente, en comparación con el cierre permanente con barreras fijas en el tiempo y el espacio.

Con la herramienta de apoyo para la toma de decisiones Marxan, formulamos un cierre de pesquerías permanente que priorizó las áreas usadas con frecuencia por los tiburones marcados y que consideraba a las áreas percibidas como altamente valiosas para las pesquerías. Para explorar cómo el tamaño del cierre permanente se comparaba con un conjunto de cierres con áreas y tiempos alternativos (es decir, donde las áreas se cerraron a la pesca en diferentes momentos del año) usamos un análisis de clúster para agrupar los meses que tuvieron arreglos similares a las unidades de planeación seleccionadas (informadas por el movimiento de los tiburones durante ese mes) en dos cierres de tiempo-área. Los tiburones fueron consistentes en el tiempo y dirección de sus movimientos migratorios, pero el número de tiburones marcados generóunagran diferencia en la ubicación del cierre permanente; se necesitaron 30 individuos para capturar la heterogeneidad del comportamiento. Los cierres de tiempo-área de la temporada de secas (mayo–enero) y la de lluvias (febrero–abril) abrieron a la pesca un 20% y 25% más de unidades de planeación, respectivamente, en comparación con el cierre permanente con barreras fijas en el tiempo y el espacio. Nuestros resultados muestran que la telemetría tiene el potencial para informar y mejorar el manejo espacial de las especies móviles y que el componente temporal de los datos de rastreo puede ser incorporado a las priorizaciones para reducir los posibles impactos del manejo sobre las pesquerías establecidas.
保护区网络和禁渔区的最佳设计需要依赖物种出现信息以及人为影响与相关物种互作的知识。然而，在 适当的时空尺度下调查移动且隐秘的物种仍是ー项挑战，它可能会掩盖特定生境的重要性，导致难以确定应保 护哪些地区以获得最大的保护成效。本研究分析了遥感获得的位点如何帮助指导禁渔范围和时间，以减少对受 胁迫物种的误捕。我们利用植人声波发射器和一批水下声波接收器对四十只露齿鲨(glyphis glyphis)的亚成体 进行了22个月的监测。利用决策支持工具Marxan软件，我们制定了ー个永久性禁渔计划,优先考虑了标记鲨鱼 个体频繁利用的区域，同时也兼顾了对渔业发展有高价值的区域。为了比较永久禁渔和时间-区域禁渔(即每年 不同时间在不同区域禁捕)的替代方案，我们用聚类分析法，在选定规划单元内根据每个月鲨鱼活动情况将有相 似规划的月份分为了两个时间-区域禁渔区。结果显示，鲨鱼在迁徙的时间和方向上是一致的，但是标记盆鱼的 数量对永久禁渔区的位置设置影响很大，至少需要三十个个体来记录行为异质性的信息。旱季(五月到一月)和 雨季(二月到四月)的时间-区域禁渔区相比于有固定时空边界的永久禁渔区，分别多开放了20%和25% 的规划単元 用于渔业发展。我们的结果表明，遥测技术有望为移动物种的空间管理提供信息和帮助，而追踪数据的时间成 分可以纳人优先保护规划中，以减少管理对现有渔场的可能影响。</abstract><cop>United States</cop><pub>Wiley</pub><pmid>30963642</pmid><doi>10.1111/cobi.13328</doi><tpages>12</tpages><orcidid>https://orcid.org/0000-0003-1136-5489</orcidid></addata></record> |
