For example, say you live in the Northeast. Here's a trimmed-down version of that area's guide:

Crab: Dungeness, Stone
Lobster: Spiny (US)
Salmon (Alaska wild)+
Scallops: Bay (farmed)
Trout: Rainbow (farmed)
Tuna: Albacore (troll/pole)
Yellow (Meaning: Not great, so try to minimize)
Black Sea Bass
Haddock (hook and line)
Scallops: Sea (wild)
Shrimp (U.S., Canada)
Tuna: Bigeye, Yellowfin (troll/pole)
Red (Meaning: Avoid)
Chilean Sea Bass/Toothfish*

And to get even fussier, they provide a "Super Green" list as well. This list takes the larger list of sustainable seafood and picks the ones that are healthiest for you because they tend to contain the least environmental contaminants and the most omega 3s. That Northeasterner will find Super Green options like farmed mussels, oysters, rainbow trout and Coho salmon, as well as wild albacore tuna, Pacific sardines and Alaskan salmon.
See, it's just that easy.
