Fine scaled estimates of fishing effort are necessary in order to provide relevant information for resources management and to characterise the potential impacts of fishing on species and habitats.
Knowledge on the fishing activities with high-resolution, from spatial, temporal and quantitative points of view, is a challenge for professional fishing and for the implementation of specific public policies.
To address this, Geo4Seas proposes a set of solutions to identify fine-scale fishing areas and characterize the intensity of fishing using heterogeneous data (Le Guyader, 2012, Le Guyader et al., 2017):
- regulatory information
- key informants’ data,
- AIS data,
- landings data,
- …
