Despite the economical importance of wild European sea bass, little is known concerning its spatial structure and dynamics. Yet, in a context of climate change, significant recruitment variability and a northward distribution shift of Northeast Atlantic sea bass have been observed over the past two decades. In the present study, we used coupled models (simulating hydrodynamics, transport and bioenergetics) over a period to investigate the impact, on nursery settlement, of contrasted hydroclimatic conditions in the Northeast Atlantic. Maps of larval dispersal as well as connectivity matrices between spawning grounds and coastal/estuarine nurseries showed significant spatio-temporal transport and growth variability whose relation to environmental factors is explored.
