The deep-sea blue and red shrimp Aristeus antennatus is a valuable fishing resource in the Northwestern Mediterranean Sea, currently under a local co-management plan in the port of Palamós (Spain). The management measures, although effective, might benefit other ports due to the dispersal patterns of the species pelagic larvae. Gathering information about A. antennatus larval distribution is a key step to describe these patterns, towards the establishment of well-dimensioned management measures. After a first detection of its larvae as the dominant species in the decapod community in Blanes submarine canyon, this broader approach tackles the entire management area along the Eastern Spanish Mediterranean coast (Geographic Subarea 6; GSA 6). Zooplankton sampling was carried out at 101 stations in surface waters (0.5–1 m) and in 8 stations in stratified vertical sampling (0–1200 m) during July–August 2016. Over 6500 A. antennatus larvae of all known stages were found, the first protozoea (PZ I) representing over 95% of the total. This is the first study taking into account the vertical migration of A. antennatus larvae, and we observed a broad distribution of PZ I throughout the water column. Plankton observations of the species larval distribution were supported by an Individual-Based Model suggesting aggregations in the northern submarine canyons, influenced by cold waters from the Northern Current and the geomorphology of the Ibiza Channel. The present study proposes a division of the GSA 6 in three zones to improve fishery management measures.

深海蓝红虾Aristeus Anteus是地中海西北部宝贵的渔业资源，目前在帕拉莫斯港（西班牙）的当地共同管理计划下。管理措施虽然有效，但由于远洋幼虫物种的扩散模式，可能会使其他港口受益。收集有关A.天线的信息幼虫分布是描述这些模式的关键步骤，以建立规范的管理措施。在第一次检测到其幼虫是 Blanes 海底峡谷十足目动物群落的优势物种后，这种更广泛的方法解决了西班牙东地中海沿岸的整个管理区域（地理分区 6；GSA 6）。2016 年 7 月至 8 月期间，在地表水 (0.5-1 m) 的 101 个站点和分层垂直采样 (0-1200 m) 的 8 个站点中进行了浮游动物采样。 发现了 6500 多只所有已知阶段的触角触角幼虫，第一个原生动物 (PZ I) 占总数的 95% 以上。这是第一项考虑到触角 A.垂直迁移的研究幼虫，我们观察到 PZ I 在整个水柱中的广泛分布。浮游生物对物种幼虫分布的观察得到了基于个体的模型的支持，该模型表明北部海底峡谷中的聚集受到来自北方洋流的冷水和伊维萨海峡地貌的影响。本研究建议将 GSA 6 划分为三个区域，以改进渔业管理措施。
