Oceana, the organization tasked with protecting the world's oceans, has recently launched a new ad campaign to preserve bluefin tuna.
The 30-second spot features Adrian Grenier (Entourage, The Devil Wears Prada) free-diving with schools of bluefin tuna, while his voiceover informs us of their plight.
Eating sustainable seafood may sound like a full-time job, but it doesn't have to be that difficult. True, there are a lot of middle-of-the-road fish---those where it would be better to avoid, but its not quite as imperative. If you're just starting, ignore those for now. Focus on eliminating the fish truly in danger of being wiped out, or, in some cases, where the bycatch from them does incredible harm.
Bluefin tuna falls into this category. They mature a little slower than their tuna brethren, so are often caught before they have spawned. Recently, the gulf oil spill has threatened one of only two spawning sites for Atlantic bluefin tuna.
These are amazing fish, and make for really tasty sushi. I encourage you to lay off for a bit, let them repopulate and allow world agencies to devise a plan to catch them sustainably, then we can all enjoy them responsibly for many many years.
