Hi Vera,

I don't eat sushi all that much, but you definitely still see bluefin tuna on the lists locally, so I would say a) don't eat at those places, and b) call them to tell them that you're not going to eat there because they have an endangered species on their menu and it's unacceptable. If you say something like "I really like sushi and would love to eat at your restaurant but I refuse to support any business who puts endangered species (or overfished species, or unsustainably caught species, etc.) on their menu, that might catch their ears. No one wants to hear that they are losing potential business, but people who boycott places for certain reasons may also not necessarily tell those businesses, in which case they may stay oblivious to the problem indefinitely. Give managements a reason and an incentive to change old habits. I want to stop frequenting a ton of restaurants who all use styrofoam to-go boxes (and sometimes even styrofoam plates for every meal served!!) but I know it will do no good unless I complain about it to them directly and tell them that I won't come back until they stop using it.

Good luck!
Elena
