Tuna
behavior and ecology:
tropical tuna fisheries in the Indian Ocean, their impacts on the high seas
ecosystems and how they interplay with the physical and biogeochemical
environment. These various interactions are used to develop an ecosystem
approach to tuna fisheries.

Mesoscale
studies (study
area: Mozambique Channel): how mesoscale eddies and turbulence affect the
distribution of phytoplankton and marine top predators (tuna, seabirds), and
its role in the connectivity between distant ecosystems. This research work is
based on shipborne observations (including physical oceanography, experimental
fishing and electronic tagging of tuna and billfish), satellite data (SST, sea
colour, altimetry) and ocean/ecosystem models products.
