Scrod or schrod (/ˈskrɒd/) is 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 whitefish. From smallest to largest, the categories are scrod, market, large, and whale. In the United States, scrod haddock or cusk weighs 1+1⁄2–3 pounds (0.7–1.4 kg); scrod cod 1+1⁄2–2+1⁄2 lb (0.7–1.1 kg); and scrod pollock 1+1⁄2–4 lb (0.7–1.8 kg). The exact weight categories are somewhat different in Canada.
