Spatial changes in the sensitivity of Atlantic cod to climate-driven effects in the plankton
International audience Recent strategies to sustain fish stocks have suggested a move towards an ecosystem based fisheries management (EBFM) approach. While EBFM considers the effect of fishing at the ecosystem level, it generally struggles with climate-driven environmental variability. In this stud...

International audience Recent strategies to sustain fish stocks have suggested a move towards an ecosystem based fisheries management (EBFM) approach.
