COD. Syn. Ga′dus Mor′rhua (Ph. L.), Mor′rhua vulgaris (Linn.), Asel′lus (Pliny), L. A fish common in the seas of the northern hemisphere, from about 40° to 75° of latitude. The flesh forms a most wholesome and excellent article of food. The best fish are very thick about the neck; and, when fresh, are marked by the redness of the gills, freshness of the eyes, and the whiteness and firmness of the flesh. The fish so largely imported from Newfoundland (Newfoundland fish) are cod beheaded, split open, gutted, and salted. They are caught by millions on the ‘Grand Bank.’ Cod-sounds are pickled in brine and also made into isinglass. The spawn is made into CAVIARE, and the liver is both pressed and boiled for its oil (see below).
Cod is generally cooked by boiling it, but is sometimes baked, or cut into slices and broiled or fried. Cod’s head and shoulders with oyster sauce is a favorite dish. Shrimp and anchovy sauce are also good additions.
COD-LIV′ER OIL. Syn. Mor′rhuæ o′leum, B. P.; O′leum jecor′is Asel′li, L.; Huile de Morue, Fr. The oil obtained from the liver of the common cod (oleum e jecore comparatum).
