Two Tales of Bluefin Tuna
Following up on yesterday's post about the fishermen's strike in Japan:
Russ Parsons of the L.A. Times blogs about how strikes and high fuel costs are affecting the availability of tuna and other fresh seafood in the U.S. He also quotes Jesse Marsh of our Seafood Watch fisheries research team on the possible long-term impacts if fuel prices remain high.
Our Stanford University colleagues in Barbara Block's research lab are also blogging, this time about their success in placing electronic data tags on Pacific bluefin tuna during last week's expedition out of San Diego. They put 112 new tags on bluefin, for a total of nearly 550 tagged bluefin in the Pacific since their Tag-A-Giant program began. (Monterey Bay Aquarium partners with Stanford on the program.)
As data come back documenting the migrations of these Pacific fish, we'll begin to get a better picture about their migrations across the ocean. Similar work by the Block lab in the Atlantic has resulted in more than 1,000 tags on giant bluefin over the past decade -- and a comprehensive picture of their travels through the Western Atlantic, the North Atlantic, Mediterranean and Caribbean.
There's data enough to support a dramatic reduction in fisheries quotas -- if the International Commission for the Conservation of Atlantic Tunas can muster the political will to impose it. Sadly, the commission seems unable to do more than preside over a collapse more dramatic than the 90 percent decline it's already suffered.
Calls for a moratorium on bluefin tuna fishing in the Atlantic were ignored last year. Since then, the European fishery was closed early and European chefs have begun to boycott bluefin tuna. ICCAT has another chance this November. We'll be watching.
