2004 - 2004 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Survey : CEND 10/04 (part of North Sea Groundfish Survey, Qtr 3 (FSS: IBTS3E; NSGFS))

This survey was undertaken by Cefas as part of the North Sea Groundfish
Survey, Qtr 3 (FSS: IBTS3E; NSGFS);

75 core trawl stations are completed annually, to provide distribution and
stock composition estimates for fish species. Station, catch, length (all
species) and biological data (selected species) are collected using research
vessels and GOV trawls. Benthic catches are also recorded. These annual
surveys (ongoing) are carried out in support of EU data regulations and as
part of the International Bottom Trawl survey. Additional aims include
collection of water temperature, salinity and litter data.

Survey took place between 04/08/2004 and 06/09/2004 on CEFAS Endeavour

Equipment used during this survey :

- Benthic Sampling Gear Jennings 2m Beam Trawl Standard spec.
- Otter Trawl GOV 34 45 SWest IBTS Spec No Bridle Kite RockHoppers
- Otter Trawl GOV Long Wing 36/47 Standard IYFS Spec.

Survey operations were undertaken on 235 stations

164 different species were caught on this survey

本调查由Cefas（英国食品标准局海洋科学中心）负责实施，作为北海底栖鱼类调查第三季度（FSS: IBTS3E; NSGFS）的一部分；年度内完成75个底栖拖网站点的调查，以提供鱼类种群的分布和组成估计。通过科研船只和GOV拖网收集站点、捕获量、长度（所有物种）以及生物数据（特定物种）。同时记录底栖捕获物。这些年度调查（持续进行中）旨在支持欧盟数据法规，并作为国际底栖拖网调查的一部分。此外，调查目标还包括收集水温、盐度和垃圾数据。调查于2004年8月4日至2004年9月6日在CEFAS Endeavour号上进行。本次调查使用的设备包括：
- Jennings 2米梁式底栖采样设备标准规格
- GOV 34 45 SWest IBTS规格无缰绳风筝岩跳蚤拖网
- GOV长翼36/47标准IYFS规格拖网
- Swansea规格Van Veen抓斗。调查在235个站点进行，捕获了164种不同的物种。
