2006 - 2006 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Survey : CORY 5/06 (part of North West Groundfish Survey, Qtr 3 (FSS: NWGFS))

This survey was undertaken by Cefas as part of the North West Groundfish Survey, Qtr 3 (FSS: NWGFS); Station, catch, length (all species) and biological data (selected species) for each of the annual surveys in the Irish Sea and Bristol Channel using research vessels and 4m beam trawls. Data mainly used to create indices of abundance in support of EU data regulations and as part of an ICES funded research program. Additional aims include collection of benthic, litter, water temperature and salinity and acoustic data. Survey took place between 14/09/2006 and 07/10/2006 on Corystes Equipment used during this survey : - Beam Trawl 4m steel commercial 3/5 link mat flip up 75mm CE 40mm liner AFT - Water sampled for caesium analysis Survey operations were undertaken on 119 stations 166 different species were caught on this survey本调查由环境、渔业与水产养殖科学中心（Cefas）作为西北底层鱼类第三季度调查（FSS: NWGFS）的一部分实施。 该数据集涵盖爱尔兰海与布里斯托尔海峡年度调查中各站位的渔获数据、所有物种的体长数据以及选定物种的生物学数据，调查采用科研船舶与4米桁拖网（beam trawl）开展。本数据主要用于构建种群丰度指数，以满足欧盟数据法规要求，同时作为国际海洋考察理事会（ICES）资助的研究项目的组成部分。本次调查的附加目标还包括采集底栖生物、海洋垃圾、海水温度、盐度与声学数据。 本次调查于2006年9月14日至2006年10月7日在“科里斯特斯号”（Corystes）科考船上进行。 本次调查使用的设备如下： - 4米钢制商用桁拖网：采用3/5节链垫翻转结构，网孔75mm，带有CE认证，内衬40mm防护网，船尾作业（AFT） - 采集海水样本用于铯元素分析 本次调查共完成119个站位的采样作业。 本次调查共捕获166个不同物种。
