EN-8. The ecosystemic approach to fisherie : how to reconcile preservation and exploitation of marine resources
Philippe Cury presents the basis of the ecosystem approach to fisheries, which enables to maintain the biodiversity, the catches and the jobs. He comes back to the main steps which punctuated the creation of this approach.

EN-9. Management of an emblematic species: the bluefin tuna
With Jean-Marc Fromentin, we discover the bluefin tuna. It is fished since Antiquity, but it is subjected to strong pressure for almost three decades, which is responsible for a large decline of the populations. He evidences the scientific, political and social aspects which enabled to better preserve this emblematic species.

Continental biodiversity: rivers and forests - Introduction
In this third part, you will discover the biodiversity of the terrestrial and continental aquatic environments. Those environments are extremely diversified and are subjected to very specific dynamics, like intermittent rivers or ecological successions of the forest environments. Some of those environments present important physicochemical variations, like the rivers, from the spring to the estuary. The biodiversity is very rich in those environments, and several preservation prospects are presented.
