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.本系列六次调查旨在收集有关鱼类资源的生物数据，以支持欧盟数据收集法规（DCR）。调查采用了葡萄牙式高网目拖网（PHHT）和4米测网进行捕捞，并选取了之前在Cefas Celtic Sea底栖鱼类调查中已捕捞过的站点网格。该站点网格并非固定目标，根据天气、捕获率和/或采样需求进行调整。
