1992 - 1992 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Survey : CIRO 9/92 (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 14/08/1992 and 10/09/1992 on Cirolana

Equipment used during this survey :

- Bottle Casts Nansen bottles Reversing surface and bottom
- Otter Trawl GOV Long Wing 36/47 Standard IYFS Spec.

Survey operations were undertaken on 150 stations

81 different species were caught on this survey

本次调查由Cefas（英国海洋科学中心）发起，作为北海底层鱼类调查（Qtr 3，FSS: IBTS3E; NSGFS）的一部分；每年完成75个核心拖网站位调查，旨在为鱼类种群提供分布和组成估计。通过研究船和GOV拖网收集站位、捕获量、长度（所有物种）以及生物数据（特定物种）。同时记录底栖生物捕获情况。这些年度调查（持续进行中）旨在支持欧盟数据法规，并作为国际底拖网调查的一部分。此外，还旨在收集水温、盐度和废弃物数据。调查于1992年8月14日至1992年9月10日在Cirolana进行。调查中使用的设备包括：瓶式投放的Nansen瓶，用于翻转表层和底层的观测；GOV长翼36/47标准IYFS拖网。调查在150个站位进行。本次调查共捕获81种不同的物种。
