Ecosystem objectives in fisheries management usually flow from high-level national policies or strategies and international agreements. Consequently they are often broadly stated and hence are difficult to incorporate directly in management plans.

Practical Approaches to Ecosystem - Based Fishery Management

Ecosystem-based Management of Coral Reef Fisheries

To date, this assumption has never been proven; and spillover is generally measured as movement of ...

Ecosystem services: from theory to implementation.

The challenge is to turn this recognition into incentives and institutions that will guide wise investments in natural capital, on a large scale. Advances are required on three key fronts, each featured here: the science of ecosystem production funct...
