I don't know if anyone else has this quandary, but I spend way too much time trying to pick out a fish for dinner. I desperately try to remember which is good, which is bad and what is actually terrible. I know some basics: farmed salmon-bad... okay, that's pretty much the extent of it. It definitely takes considerable concentration (and a smartphone) to be steered in the right direction. Here is a new list I found with 12 fish you should avoid along with their explanations. This list is new to me, but looks great. In the past I have always found the Monterey Bay Aquarium to be a good source as well. Now with their handy phone app, maybe I won't have to spend so much time pondering my fish options after all!
