Survey : HUXL/63/1905 (part of CEFAS Historic surveys)

This survey was undertaken by Cefas as part of the CEFAS Historic surveys;

Station and biological data collected during research surveys carried out by
Cefas (formerly Directorate of Fisheries) in seas around the UK, mostly in the
North Sea, since 1902. The survey hauls are not laid out systematically as a
grid, as in current International Bottom Trawl Surveys (IBTS) and are widely
distributed over (especially) southern and central North Sea areas. Gears and
protocols were not standardised throughout, due to the long term nature of the
series. Surveys took place in each season. Data are lacking for the periods of
both World Wars. In some periods (e.g. the early 1900s), all species caught
were recorded, whereas in other periods (e.g. 1920s-30s), only the key
commercial species (e.g., Plaice, Sole and Cod) were recorded systematically.
Note that some surveys targeted particular species (notably Plaice).

Survey took place between 06/09/1905 and 14/09/1905 on Huxley

Equipment used during this survey :

- Otter trawl Codend catch

Survey operations were undertaken on 8 stations

17 different species were caught on this survey

本项调查由Cefas（前身为渔业管理局）组织实施，作为CEFAS历史调查项目的一部分。自1902年起，Cefas在英国周边海域（尤其是北海）开展了研究性调查，收集了站点和生物数据。调查的渔获并非如当前国际底拖网调查（IBTS）那样系统性地布局成网格状，而是广泛分布在北海的南部和中部地区。由于该数据系列的长期性，渔具和协议并未在整个过程中实现标准化。调查在每个季节均有所开展。两次世界大战期间的数据缺失。在某些时期（例如20世纪初），记录了所有捕获的物种，而在其他时期（例如1920年代至1930年代），仅系统地记录了关键的商业物种（例如鳎鱼、鳎鱼和鳕鱼）。请注意，某些调查针对特定物种进行（尤其是鳎鱼）。1905年6月6日至9月14日，在Huxley号上进行了调查。本次调查所使用的设备包括：

- 集鱼网鳕鱼捕捞
调查操作在8个站点进行，共捕获了17种不同的物种。
