April 29, 2008 | On the subject of seafood, I'd always been well intentioned but underinformed. It's not that I didn't care, didn't hear the dispatches about avoiding Chilean sea bass or the antibiotics in shrimp, but I felt overwhelmed by a stream of investigative reports and gloomy forecasts. Overwhelmed is how a lot of us feel these days, as food-related crises proliferate in the news -- potentially contaminated beef from sick cows, possibly toxic crop spraying in California, food riots in Haiti. The bleak onslaught can make eating ethically seem like a daunting, if not impossible, goal. It was with this sense of doom that I began Taras Grescoe's "Bottomfeeder: How to Eat Ethically in a World of Vanishing Seafood." But by the time I was done, I found myself holding court in the canned fish aisle explaining to fellow shoppers the difference between skipjack and albacore tuna.

Grescoe, a Canadian nonfiction writer and respected food and travel journalist, takes us on an international tour of controversial cuisines -- shark fin soup in China, whale sashimi in Japan, monkfish tail in New York City -- meanwhile offering an overview of the corrupt practices that have put the oceans (and our health) in danger. The portrait he paints is grim: oceanic dead zones that, because of pollution and overfishing, can no longer support organic life; salmon farms polluted by pesticides and disease; ruthless bottom trawlers with nets that can destroy entire ecosystems.

A warning is not a death sentence, however. The book empowers consumers to ask the right questions -- if the halibut is from the Atlantic or Pacific, for instance, and whether the lobster pasta is actually made from monkfish, which is endangered. And asking these questions will make it possible to enjoy seafood for years to come. Eating has become about a lot more than mere nutrition or pleasure these days; it carries the burden of being environmentally and economically aware. Which means that we need to be not just well intentioned but informed as well. The future of seafood relies on knowing where -- and even if -- your salmon used to swim.

Salon spoke with Grescoe on the phone from his home in Montreal.

How did you first start caring about sustainable seafood?

I was getting sick of food writing and of writing food porn. I thought the form was shot. There are the Anthony Bourdains having these "to die for" meals and having a great time, but no one's really talking about what's at the end of the fork and where it comes from. There's this food-writing convention where you're not supposed to think about the origins of your food and suspend any judgment against people who eat endangered songbirds, or whatever. It's been a real privilege to be able to write articles about this kind of thing. But after a while, you know what? You're contributing to the impoverishment of the world. In a way this is a bit of a "Fuck you" to the food-writing world.

You think food writers have an ethical responsibility to discuss sustainability?

Yes, they do, and for the last 10 to 15 years people haven't been shouldering that responsibility. We've lived through a strange time where there were great expense accounts, but in the context of food riots around the world, how much time do you want to spend writing food porn? If you don't start looking at where your food comes from, you're just being irresponsible.

What about the rest of us? Why should we bother learning about our seafood?

Cultures where people do care about where their food comes from have richer lives because the supply chains are shorter. Spanish people, even the ones who live in Madrid, pride themselves on knowing a farmer.

North Americans are quite conscious about their health, and fish is amazing for your health. There are theories out there right now that early hominids' brains were able to grow because they had a source of omega 3 [fatty acids] in their diet that is only possible with a shore-based diet. In North America we consume a lot of fish, but we eat the bad fish. Eating these fish disrupts the food chains in the ocean and creates a situation where there are all these strange trophic cascades. All of a sudden there are more jellyfish in the ocean, more bottom feeders. We're changing the very nature of the oceans.

What's the most important thing fish eaters should take away from your book?

The message is contained in the title. You should probably stay away from fish at the top end of the oceanic food chain right now. Big fish like tuna, swordfish, shark -- these are traditionally middle-of-the-plate proteins in the world's best restaurants, and they're actually a lot of the riskiest ones in terms of having things like mercury and, in the case of salmon, persistent organic pollutants. If you really want to do some good for the oceans, start exploring the pelagic fish -- whiting, for example; the schooling fish like sardines and anchovies; things that we don't even really cook right now but are quite popular in other countries.

OK, so we can eat sardines, anchovies ...

Oysters, pollock -- it's got a terrible name, but that's the stuff that goes into [McDonald's] Filet-O-Fish sandwiches. It's very abundant. There's trout, which isn't a bad fish. Sablefish and Arctic char are currently quite abundant. I love herring, and there's herring off the Pacific Coast as well. Try to the best of your ability to buy things locally.

And which big fish are we supposed to stay away from?

Avoid big predator fish -- shark, swordfish, Chilean sea bass, tuna, with the exception of skipjack, which is pretty abundant light tuna. Avoid farmed carnivorous species like shrimp, salmon and bluefin tuna. Avoid imported farmed seafood because domestic standards are a lot higher. The exception to that is [domestically farmed] salmon, which is terrible.

Can you explain what's so bad about salmon farms?

Salmon from these farms tends to be full of persistent organic pollutants, [some of which] are highly carcinogenic. Salmon farmers grind up smaller fish like anchovies, sardines and anchoveta to make the pellets -- all of which should be going to feed humans, not making deluxe fish, especially in the context of food riots -- and salmon farms have been proven to spread disease and parasites like sea lice to wild fish populations, among them sea trout in Ireland and wild salmon in British Columbia.

Some farmed fish aren't so bad: trout and Arctic char, which are raised inland so there's no risk of spreading parasites to wild fish; tilapia and carp, which are herbivorous species; and of course oysters and mussels, which actually help clean the oceans of their excess plankton.

So is there a way we can safely enjoy salmon?

If you want to make a canned salmon sandwich or something like that, look for any can that has Alaska stamped on it. They should be all over. It's fantastic for you, and it's really clean protein. Don't buy Atlantic salmon. That's definitely farmed, because Atlantic salmon is commercially extinct right now. Those that appear in streams and rivers are actually escaped fish from salmon farms. Chinook and certain runs of salmon in California and Oregon are doing really badly this year. Nobody's quite sure what's going on -- it could be dams, fertilizer, ocean conditions. In British Columbia, they're not doing as well either, but Alaskan stocks are pretty good. And there's organic farmed salmon. I want to give those guys some credit. If you go to a restaurant and the menu says "organic farmed salmon," then the fish was raised under higher standards and it's probably better for you. The question is whether the fish are still spreading parasites to other fish. You can eat that in sort of "half-conscience." It's important to realize that right now about 45 percent of the seafood we get is farmed. And this is having a huge impact on the livelihood and well-being of people in other cultures. In the book I talk about how salmon farms affect native people in British Columbia and people who are affected by shrimp farms in India.
