Cod, the Common, or Gadus Morhua, L. an inhabitant of the. ocean, which is from two to four feet long, and weighs from 12 to 20lbs.: it is found only in the northern parts of the world, between the latitudes of 66 and 50 degrees. The principal fishery for cod, is on the banks of Newfoundland, where they are caught in numbers sufficient to furnish employ for nearly 15,000 British seamen, and to afford subsistence to a still more numerous body of people at home, who are engaged in the various manufactures, which so extensive a fishery demands.
The food of the cod consists of small fish, worms, crabs, etc.: their digestion is so vigorous, as to dis-solve the greatest part of the shells they swallow. Hence they are extremely voracious, and catch at any small object they perceive agitated by the water, even stones and peb-bles, which are frequently found in their stomachs. Of the salted roe of this fish, not less than fifteen ship-loads are said to be annually exported from Norway to France ; whose fishermen employ that substance for the taking of anchovies in the Mediterranean. From the liver of cod, a very good train-oil is obtained; and the tongues, when salted, are esteemed a great delicacy, and therefore often imported from Newfoundland. Isinglass is also prepared from their air-bladders, by the fishermen of Iceland ; a process which peculiarly merits the attention of the inhabitants of the north of Scotland, where these fish are caught in great abundance. - See Isinglass.
