Abstract
Considerable research has been conducted in the past 15 years around the
Eastern English Channel ecosystem. Data collected since the 1970s on the
biotic and abiotic compartments have been collated and mapped out in the
mid-2000. This spatially explicit information formed a sound basis to
improve knowledge on, and model, the functioning and dynamics of key
ecosystem compartments, with a focus on fl atfi sh species and fi sheries and
their interactions with other sectors of activity (aggregate extractions,
maritime traffi c). The more recent ongoing works are dedicated to the
integration of those processes into several complementary end-to-end
ecosystem models.

Introduction
The English Channel concentrates a rich ecosystem along with intense and diverse human activities. At the same time, the Channel is a relatively
well-circumscribed geographical area, “a world
within Europe”, which makes it an appropriate
site for investigating the complex interactions
between intensive and diverse human activities
and this ecosystem.
The English Channel is fi rst a productive ecosystem coupling high and diversifi ed pelagic and
benthic productivity. It is home to many commercial species, encompassing their spawning and
nursery areas and migratory routes.
