That would hardly be a test. There are other commonly served fish such as Orange Roughy, Chilean Seabass (Patagonian Toothfish) and Atlantic Cod that are rapidly being depleted. There are also farmed fish that are plentiful but are raised in environmentally damaging conditions such as Latin American Tilapia and Asian Shrimp.

There are competing lists regarding sustainable and environmentally sound seafood, each with different methodology. Even worse, there are some seafoods that are sustainable and environmentally sound but only when sourced from certain regions.

There are reasonable crowd pleasers available such as line caught Alaskan wild salmon, but how would you know that it is line caught Alaskan wild salmon? It could be net caught or farmed Atlantic salmon. U.S. west coast Dungeness Crab is sustainable but others are not. Some farmed bivalve shellfish actually benefit the environment but some wild ones are disappearing.
