Résumé
Indicators are essential tools for policy making, public communication and the provision of scientific advice. In the fisheries realm indicators have been increasingly used to advising on fish and shellfish stock management, especially since the precautionary approach to fisheries management was developed. They are now becoming a cornerstone of the wider ecosystem approach to the management of all human activities. In this section we provide some recent examples of methods we developed for creating and selecting pressure indicators and ecological indicators derived from different types of information (scientific survey data, commercial fisheries data) for a range of ecosystems, covering pelagic, demersal and deep-water systems.
