The Ocean Perch Story
Atlantic ocean perch are not actually perch. They're rockfish that travel in large schools. They are called redfish in New England and eastern Canada and should not be confused with redfish from the Gulf of Mexico, which are drums.
Ocean perch is a leading retail product in the Midwest, where the name "perch" is an easy sell because of its freshwater connotation. Atlantic ocean perch are found in offshore waters of the Atlantic from southern Labrador to the Gulf of Maine and on the other side of the Atlantic off Germany, Denmark, Iceland and Norway.
Most Atlantic ocean perch are trawl-caught and weigh up to 5 pounds, though market weights typically range from 1 1/2 to 2 pounds.
