Fishing Activity for UK Vessels 15m and over 2009

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.本数据集提供了指定日历年度内被认定开展捕捞作业的15米及以上英国商业渔船的捕捞活动汇总数据。本次汇总数据已按照与作业对海床、环境或生物群落的潜在影响相关的渔具类别进行分类聚合。位置数据提取自基于GPS的船舶监控数据。在最高空间分辨率层级（对应0.05度子矩形网格）下，本数据集分别针对使用被动渔具类型和机动渔具类型的船舶，提供以下聚合数据项： 1. 仅用于内部信息查询：各渔具类型对应的参与作业的15米及以上渔船数量 2. 捕捞时长（单位：分钟） 3. 2011年起新增作业量（单位：千瓦小时，计算方式为：将每份船舶监控报告对应的作业时长以小时为单位，乘以作业发生时对应船舶的主机功率） 4. 各渔具类型对应的上岸活鱼总重量（单位：吨） 5. 各渔具类型对应的上岸活鱼总价值（单位：英镑）
