Less expensive fish being passed off as higher priced fish, overfished species mislabeled as sustainable ones When it's so easy to get away with it, there's a lot of cheating going on. Caveat emptor.

Whenever the Florida tv stations run out of ideas for other investigative reporting, it's pretty common for them to do another round of 'Is your grouper sandwich really grouper?' using those kinds of lab tests. Which ends up interesting in the sense that some places you'd tend to assume were trying to pass off le chat Vietnam as grouper or mahi are selling the real deal and others that you'd thought were reputable turn out to be serving something it wasn't either intentionally or because their wholesaler was scamming them.
Oddly, the most common state seafood labeling complaint in Florida is from Asian restaurants calling something crab when it's really krab.
