Our planet’s oceans are in peril. Fish populations are collapsing from decades of overfishing. Some researchers estimate that there will be no seafood left in just 30 years.

Climate change is touching the seas, too. Rising water temperatures and acidification from dissolved carbon dioxide are already threatening delicate coral ecosystems, and fish may be next.

Suggested solutions range from the extreme (dumping iron or calcium carbonate into the sea) to the ordinary (cutting back on fishing quotas). And here we are in the middle of this, the bewildered shoppers wandering around the grocery store, unsure of which fish to eat.

Wild fish. Farmed fish. Line-caught fish. Rod-and-reel fish. Mercury-tainted fish and rich-in-beneficial-omega-3-oil fish. Amid conflicting and confusing advice, it is hard to decide what to bake, broil or stew for dinner. This interactive examines some popular seafood choices, combining data from the Monterey Bay Aquarium Foundation, the FDA and the USDA. Bon appetit.
