It’s a rare occurrence that a black-and-white choice presents itself in the complicated world of ethical seafood buying. The conscientious diner striving to save depleted cod stocks might choose a farmed tilapia for his fish and chips only to learn that his tilapia may have been grown in China and high doses of antibiotics and toxic antifoulants could have been administered on the farm. A shrimp lover might eschew farmed shrimp because of the damage shrimp farming can do to mangrove forests, only to learn that shrimp caught in the wild often result in significant bycatch of unmarketable fish and sea turtles.

It is a choice made not at the fresh seafood counter but in that humdrum aisle where the cans are kept. Canned salmon or canned tuna? Which is better?

But in spite of all of this noise in the marketplace, there are actually a few very clear choices. One of them presents itself each time we step into a large supermarket. It is a choice made not at the fresh seafood counter or even in the frozen section. It is made in that humdrum aisle where the cans are kept. The choice is there before us: canned salmon or canned tuna? Which is better?
