What is the fish listed as "scrod" in New England restaurants?

The name comes from a Middle Dutch word "schrode" meaning a strip or shred.

In New England scrod may be immature cod or haddock weighing 11/2 to 21/2 pounds.

Sometimes the term is applied to cusk of about the same weight, or to pollock weighing 11/2 to 4 pounds.

When fishermen use the word, they are usually referring to gutted small haddock.
