Consumer Reports sent fresh and frozen fish samples from the Northeast to be tested in a lab, and the results were dramatic.

The magazine purchased 190 pieces of seafood at restaurants and stores in New York, New Jersey and Connecticut and found that more than 20 percent was mislabeled as different species of fish or misidentified by employees, according to an article in its upcoming December issue.

Consumer Reports said all of the 10 of the "lemon soles" and 12 of the 22 "red snappers" proved to be other species.
