Are they serving you a healthy fish?

When I read stuff like this, it makes me very angry! Who comes up with such unethical ideas and how they don't see connection between what they are injecting in the fish and what their children and future generations will be eating.  Reminds me again to only go to restaurants that I trust. I do prefer home cooking on most days.
