Catch-22 vocabulary

a small cod or haddock, and sometimes other whitefish, used as food. It is usually served as a fillet, though formerly it was often split instead.

In the wholesale fish business, scrod is the smallest weight category of the major white fish. From smallest to largest, the categories are: scrod, market, large, and whale. In the U.S., scrod haddock or cusk weighs 1.5–3 lbs.; scrod cod 1.5–2.5 lbs.; and scrod pollock 1.5–4 lbs. The exact weight categories are somewhat different in Canada.

Scrod is common in many coastal New England and Atlantic Canadian fish markets and restaurants, although using the name 'scrod' without the species is in principle mislabeling.
