Global atlas of AIS-based fishing activity: challenges and opportunities
2019
Taconet, M. | Kroodsma, D. | Fernandes, J.A.
With the advances in information technology, it is becoming possible to create a global database of fishing effort by gear type with an unprecedented spatial and temporal resolution. Such a database has the potential to assist with fisheries management and research around the globe. When initiating this publication, FAO intended to present this potential by reviewing AIS-based data in context of global and regional knowledge on fisheries, and to communicate the main findings as well as strengths and limitations of these data and current processing methodology. The aim of this document, hereafter referred to as the Atlas, is to enable stakeholders to understand the opportunity and challenges of mapping and analysing fishing activity with AIS data. For each FAO Area, based on AIS data, this Atlas presents the number and percentage of vessels broadcasting AIS, the spatial patterns of presence and intensity of fishing activity, and an analysis by gear type. For these data, the Atlas includes detailed methods, case studies, and comparisons with outside data. These comparisons, explanatory text, and caveats are presented with the goal of helping member countries understand how this new dataset can be applied. To ensure the accuracy of the conclusions, over 50 fishery experts from around the world reviewed and assessed the maps, charts, and supporting text produced by the authors and editorial team.
