Mapping fishing effort: Combining fishermen's knowledge with satellite monitoring data in English waters

摘要

We describe and analyse data on fishing effort collected by interviewing 1914 fishermen between 2007 and 2010. Combining socio-spatial data collected through a voluntary mapping project called "FisherMap" with UK and European vessel satellite monitoring data provides high resolution, national-scale maps of distribution and relative intensity of fishing for six gear types. The effort maps show, for the first time, a large scale and holistic approach to mapping fishing effort by including the under-reported, yet significant, inshore fishing fleet (85% of registered vessels <15 m). The data from this study have been used to facilitate the planning, management advice and subsequent designation of 38 inshore Matine Conservation Zones. The authors conclude that, effective management of the inshore marine environment requires up-to-date, high resolution and holistic maps of fishing effort that can be obtained only through validated interpretation of inshore vessel monitoring system data.
