Title

Survey : HUXL/70/1906 (part of CEFAS Historic surveys)

Abstract

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 22/03/1906 and 29/03/1906 on Huxley Equipment used during this survey : - Grimsby style otter trawl Codend with mesh 6.8cm - Lowestoft smack beam trawl 43ft 13.1m Survey operations were undertaken on 6 stations 47 different species were caught on this survey

Quality and validity

Lineage

Surveys range from 1902 until the 1970s. Over the decades, at least 11 different Research Vessels (RVs) carried out surveys using different gear deployments and catch sampling protocols over time. Early, steam-powered vessels towed the trawl at a speed of approximately 2 knots, whereas in current, diesel-powered vessels this is standardised at 4 knots. The data constitute a highly valuable information source, however, owing to the above, data analysis and interpretation requires caution. Species and Gear code lists are available via the additional information source field.
