Summary

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 04/07/1974 and 16/07/1974 on Cirolana

Equipment used during this survey :

  • Otter Trawl Semi Pelagic GOV NOP rig, Cirolana Spec.

Survey operations were undertaken on 83 stations
