Navigating the Seafood Menu
Ask your local fishmonger about Boston mackerel. That's the advice of the New York Times' Marian Burros, who researched and compiled a list of "guilt-free" fish for the paper's Dining section. What's nice about her list (which draws from resources like Oceans Alive and the Monterey Bay Aquarium) is that it looks at the both the health consequences of eating certain fish (exposure to toxins like mercury, PCBs, dioxins, etc) and the consequences for the future of certain fish stocks of being eaten (namely, collapse or extinction). On the other hand, not all the fish are readily available. Ask your fishmonger about Boston mackerel and, in most parts of the country, you're bound to be met with a blank stare -- at least until it catches on.
