THE BRONX - A new study says there's something fishy going on at grocery stores and restaurants across New York City.

According to the conservation group Oceana, fish is being mislabeled 39 percent of the time. It says some businesses are selling a less expensive fish, but labeling it as a higher-grade fish.

Oceana is calling it a "bait-and-switch tactic" to rip off consumers, and has requested that Congress intervene.
