They were disappointed.

The International Commission for the Conservation of Atlantic Tuna (ICCAT), the organization that tracks and manages Atlantic bluefin, did not find that populations had recovered when it released the results of its annual stock assessment last month.

Yet the same scientists who reached that conclusion also recommended allowing catches of eastern Atlantic bluefin to increase by 52 percent. Western Atlantic bluefin catches could grow by 25 percent. By 2020, annual quotas for eastern Atlantic bluefin could rise to 36,000 metric tons a year – a record high, according to conservationists.
