Raw data from unpublished historical 'Statistical Charts' held at the Centre
for Environment, Fisheries and Aquaculture Science (Cefas), Lowestoft, UK.
These charts provide annual and monthly fisheries statistics at a fine spatial
scale for the period 1913-81 (excluding both World Wars). More specifically,
they show the annual and monthly landings and catch rates per fish species,
and the fishing effort for various components of the British commercial
fishing fleet. These values are indicated separately for each rectangle of 1°
longitude by 30' latitude (equivalent to International Council for the
Exploration of the Sea [ICES] rectangles) as well as for the entire area
charted (generally equivalent to ICES fishing areas).
