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 04/09/1964 and 11/09/1964 on Platessa
Equipment used during this survey :
- Prawn trawl 60 75 mesh with 55mm Codend Baiting cover catch
- Prawn trawl 60 75 mesh with 55mm Codend Belly cover catch
- Prawn trawl 60 75 mesh with 55mm Codend Bottom codend cover catch
- Prawn trawl 60 75 mesh with 55mm Codend Codend catch
- Prawn trawl 60 75 mesh with 55mm Codend Top codend cover catch
- Prawn trawl 60 75 mesh with 55mm Codend Wing cover catch
Survey operations were undertaken on 24 stations
22 different species were caught on this survey

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.
