This data set provides summaries of fishing activity for UK commercial fishing vessels of 15m and over in length that are deemed to have been fishing within a specified calendar year. These summaries have been categorised into aggregated gear groups that have relevance to their potential impact on the seabed, environment, or biota. Positional data have been extracted from GPS-derived Vessel Monitoring Data. At the highest resolution, equal to 0.05 degree sub-rectangle, the following data items are provided aggregated between vessels using passive gear types or mobile gear types separately:
1. For internal requests for information only, the number of 15m and over vessels involved in each gear type,
2. Time fishing (minutes),
3. From 2011 data onwards, effort in KW Hours (calculated by multiplying the time associated with each VMS report in hours by the engine power of the vessel concerned at the time of the activity)
4. Quantity (tonnes) of live weight fish landed with gear type,
5. Value (sterling) of live weight fish landed with gear type.
