Most everything farm raised is horrible. There are some farm raised that's not bad, you have to check your source. This is a large part of my brother's field, he is a research professor at a University and has lead many studies on fish/shrimp farming among other aquaculture studies and there are ways to mitigate the problems. Obviously many companies will take the quick/cheap route. A lot of farm raised seafood comes from Thailand, which is wrought with no aqua farm regulations.
