'Mobile marine reserves' needed

Mobile marine reserves are needed to protect ocean species, say scientists.

The idea that only fixed areas of ocean can be designated as no-catch zones is out-dated, and does not reflect the very dynamic behaviour of some ocean creatures, they argue.

The spur for this new thinking is the avalanche of data coming from tagging projects.
