I’ve had that crap, too - and I do use the word “crap” advisedly. Good saltwater white fish has been incresingly expensive and hard to find, however. The world’s factory fishing fleets are quickly vacuuming up whatever’s in the oceans, and the size and catches of fish like halibut, haddock and cod are not even close to what they once were. It’s a shame, but as big as the oceans are they can’t provide fish for everyone who would like to have some.
It's just going to get worse. I read just recently that the popular Chilean Sea Bass available in restaurants now could be 85 years old. Yes, an 85 year old fish!
