Supermarkets across New York are pulling the old bait-and-switch on unsuspecting fish fans, according to a recent investigation by acting Attorney General and fish pun fanatic Barbara Underwood.

On Friday, her office released the results of their “Fishy Business" study, which outlined the "rampant mislabeling" of seafood species at supermarket chains across the state. The report found that more than a quarter of fish specimens are falsely packaged, often replaced with alternatives that are cheaper to raise and less environmentally sustainable.

The fish-dupe was most widespread in New York City, where a full 43 percent of sampled fillets were found to be an entirely different fish. Lemon sole, red snapper, and grouper were the most common targets for deception, in some cases swapped with a species containing much higher mercury levels. Twenty-eight percent of packaged "wild salmon" was also determined to be farmed salmon, despite being sold at a significantly higher cost.

Overall, nearly two-thirds of supermarket chains surveyed by the attorney general’s office had at least one instance of fish fraud. Five chains in particular—Food Bazaar, Foodtown, Stew Leonard’s, Uncle Giuseppe’s, and Western Beef—were allegedly mislabeling their fish at a rate of more than 50 percent.

“It’s clear that seafood fraud isn’t just a fluke—it’s rampant across New York,” outgoing attorney general and aspiring tabloid writer Barbara Underwood said in a statement. "Supermarkets are the last line of defense before a phony fish ends up as family dinner, and they have a duty to do more."

The report was prompted by a similar investigation undertaken by a marine conservation organization in 2012, which found a staggering amount—like, literally 100 percent—of sampled New York City sushi restaurants were guilty of fish foolery.

The attorney general promised enforcement action to ensure quality control at seafood counters. In the meantime, this authentic seafood clothesline isn't looking so bad anymore, is it?
