DAERA Annual Estuarine Fish Survey 2009

The DAERA estuarine fish survey is an annual assessment of fish communities in seven river estuaries in Northern Ireland. Data is collected primarily for the purposes of reporting to Water Framework Directive (WFD), although a subset of the data is reported to the MERMAN database for inclusion in the Clean Seas Evidence Group (CSEG) work programme.北爱尔兰农业、环境与农村事务部（DAERA）河口鱼类调查是针对北爱尔兰境内7条河流河口的鱼类群落开展的年度评估。该调查采集的数据主要用于向水框架指令（Water Framework Directive，WFD）提交报告，不过其中一部分数据子集会被提交至MERMAN数据库，以供纳入清洁海洋证据小组（Clean Seas Evidence Group，CSEG）的工作方案。
