Fishing intensity

The datasets on fishing intensity in the EU waters were created in 2020 by Cogea for the European Marine Observation and Data Network (EMODnet). It is the result of the elaboration of the International Council for the Exploration of the Sea (ICES) data on: i) Spatial distribution of average annual fishing effort (mW fishing hours) in the Greater North Sea and Baltic Sea during 2015-2018, by gear type (Beam trawls, Bottom otter trawls, Bottom seines, Dredges, Pelagic trawls and seines, Static gears). Fishing effort data are only shown for vessels >12 m having vessel monitoring systems (VMS); ii) Average annual subsurface (top) and surface (bottom) disturbance by mobile bottom contacting fishing gear (bottom otter trawls, bottom seines, dredges, beam trawls) in the Greater North Sea and Baltic Sea during 2015-2018, expressed as average swept-area ratios (SAR). Due to data confidentiality issues, VMS/logbook data are anonymized and aggregated in a 0.05x0.05 degree grid prior to submission to ICES, using the C-square geocode system (polygons). The dataset is updated yearly and as soon as new data from ICES are released.

欧洲海洋观测与数据网络（EMODnet）所采用的欧盟水域捕鱼强度数据集，由Cogea于2020年创建。该数据集系对国际海洋探索理事会（ICES）所提供数据之精炼成果，具体包括：一）2015-2018年间，在北海及波罗的海地区，以捕捞器械类型（如拖网、底拖网、底围网、疏浚船、浮游拖网及围网、静态渔具）为划分，对平均年度捕鱼强度（以马力小时计）的空间分布进行分析；捕鱼强度数据仅限于拥有船舶监测系统（VMS）且船体长度大于12米的船舶；二）2015-2018年间，在北海及波罗的海地区，由移动式接触海底的捕鱼器械（如底拖网、底围网、疏浚船、拖网）引起的平均年度水下（表层）及水面（底层）扰动，以平均扫海面积比（SAR）的形式表达。鉴于数据保密性问题，VMS/日志簿数据在提交至ICES之前，已采用C-square地理编码系统（多边形）进行匿名化处理并汇总至0.05x0.05度网格中。该数据集每年更新，并随ICES新数据的发布而及时更新。
