| Comprehensive view of the status of Atlantic bluefin tuna Posted: 09 Dec 2011 02:19 PM PST Bluefin populations on both sides of the Atlantic Ocean have declined precipitously since 1950, according to a new study.

The new model is revolutionary in its ability to account for population overlap (mixing) of this highly migratory animal on the North Atlantic foraging grounds.  |
