Acoustic telemetry as a tool for cod stock assessment
All around the world, fish stocks have declined tremendously during the last decades. Multiple causes can be addressed, working on different levels of the ecosystem: overfishing, habitat destruction and modification, pollution, disease and climate change. To restore stocks, a better understanding of...

All around the world, fish stocks have declined tremendously during the last decades. Multiple causes can be addressed, working on different levels of the ecosystem: overfishing, habitat destruction and modification, pollution, disease and climate change.
