BROOKLYN - A study done by the conservation group Oceana revealed that fish is being mislabeled 39 percent of the time in markets all over New York.

According to the study businesses are selling a less expensive fish, but labeling it as a higher-grade fish.

Beth Warren, a nutritionist, says in order to avoid this problem it's a good idea to shop at a local farmers market and to develop a friendly relationship with the seller.

Oceana is calling this the "bait-and-switch tactic" to rip off consumers. They have requested that Congress intervene.
