Data Collection Regulation Survey, Qtr 1 (FSS: DCRDC)

Six surveys of a series to collect biological data on fish stocks in support of the EU Data Collection Regulation (DCR). Fishing was undertaken using a Portuguese High Headline Trawl (PHHT) and 4m Beam Trawl, using a subset of the station grid previously fished on Cefas Celtic Sea Groundfish Surveys. The station grid was not a fixed target and was deviated from as dictated by weather, catch rates and/or sampling needs.为支持欧盟数据收集规定（DCR），本系列调查共进行了六次，旨在收集有关鱼类资源的生物数据。调查采用葡萄牙高领头拖网（PHHT）和4米波束拖网进行捕捞，所使用的站位网格为先前在Cefas凯尔特海底鱼资源调查中已捕捞的子集。站位网格并非固定目标，其位置根据天气、捕捞率和/或采样需求的变化而调整。
