14.3.1.1 ICES Rectangles ICES rectangles are the smallest spatial unit used for the collation of fisheries data by
9.
Member States. The boundaries of offshore ICES rectangles cover approximately 900nm2 and align to 1˚ of longitude and 30’ of latitude. It is however unlikely that fishing activity is evenly distributed throughout the sea area covered by an ICES rectangle.
10. Vessels of over-10m are required to submit daily European Commission (EC) log
sheets, whereas those under-10m are not obliged to do so, although voluntary submissions can be made. In addition, local fisheries officers undertake dockside checks on the under-10m fleet, as well as allocating data collected from other sources, such as monthly shellfish returns, into specific ICES rectangles.
14.3.1.2 Marine Management Organisation (MMO) Surveillance Sightings Fisheries surveillance sightings within the UK Exclusive Economic Zone (EEZ) are
11.
recorded by fishery protection aircraft and surface craft as a means of policing fisheries legislation. Fishing vessels of all sizes and nationalities are recorded. These data are used within this report to give an indication of the distribution of fishing activity by method and nationality: the data cannot be used for quantitative assessments of activity due to the low frequency of surveillance over-flights.
14.3.1.3 Fisheries Statistics Fisheries statistics and Vessel Monitoring System (VMS) data were requested from
12.
the relevant national fisheries agencies. Statistics were provided by all national agencies with the exception of France. Despite requests to Le Ministère de l’Agriculture, de l’Alimentation, de la Pêche, de la Ruralité et de l’Aménagement du Territoire, the requested fisheries statistics and VMS data have not been forthcoming. Reports produced by the Comité National des PêchesMaritime et des Elevages Marins (CNPMEM) and L’Institut Français de Recherche pour l'Exploitation de la Mer (IFREMER) summarising French fishing vessel activity and values within Round 3 Zones and the East Anglia Zone were available and have been included in the baseline.
13.
The principal datasets used relate to fishing values and effort (days fished) to evaluate:
species targeted; fishing methods used;
vessel categories (under-10m, 10m-15m, over-15m); annual variations;
