Nephrops Underwater Television Survey Functional Units

Nephrops Functional Units represent geographic area management and reporting units for Nephrops Underwater Television (UWTV) surveys. The Irish Functional units 30 divisions were based on ICES Statistical Rectangle boundaries. The prawn (Nephrops norvegicus) are common around the Irish coast occurring in geographically distinct sandy/muddy areas were the sediment is suitable for them to construct their burrows. Nephrops spend a great deal of time in their burrows and their emergence from these is related to time of year, light intensity and tidal strength. Functional units include the Aran Grounds, the Irish Sea, Celtic Sea and Porcupine Bank. Functional units for reporting purposes were created in 2002. Functional units created from merging existing ICES Statistical rectangles. Functional units created to support area management and reporting of the Nephrops shellfish marine resource. Nephrops Functional Units created by the fisheries science survey team of the Marine Institute (Ireland). Functional units completed for Nephrops UWTV reporting purposes.挪威海螯虾（Nephrops）功能单元是挪威海螯虾水下电视（Nephrops Underwater Television, UWTV）调查的地理区域管理与报告单元。爱尔兰挪威海螯虾功能单元下设30个分区，其边界均基于国际海洋考察理事会（International Council for the Exploration of the Sea, ICES）统计矩形的划定范围。挪威海螯虾（Nephrops norvegicus）广泛分布于爱尔兰周边海域，栖息于沉积物条件适宜其构筑洞穴的地理分隔型沙质/泥质海区。挪威海螯虾多数时间都栖息在洞穴中，其出穴活动与季节、光照强度及潮汐强度密切相关。该功能单元涵盖阿兰渔场、爱尔兰海、凯尔特海及波丘派恩浅滩。用于报告用途的挪威海螯虾功能单元于2002年设立，此类功能单元通过合并现有ICES统计矩形构建而成，旨在支撑挪威海螯虾这一海洋贝类资源的区域管理与报告工作。挪威海螯虾功能单元由爱尔兰海洋研究所（Marine Institute, Ireland）的渔业科学调查团队编制完成，专为挪威海螯虾UWTV调查报告工作打造。
