Chapter XIII The Common Carp
Cyprinus Carpio.—This, as well as the goldfish, Cyprinus auratus, is not a native of our country, but has been introduced from Europe, and naturalists have supposed that there is no native carp of any size in this country. I have seen a fish called the Western Carp, which, although I had no chance to more than sketch its head, was certainly a true carp, and of four or five pounds weight. It had large scales, and all the fin-rays soft, except the first anal, which was robust.
The common carp, which has increased with amazing rapidity till it is found everywhere in the Hudson River, has a small mouth, fleshy lips without teeth, large scales, three branchial rays and teeth on the pharyngeals; has the first ray of the dorsal and anal fin serrated behind, has two barbels at the angle of the mouth, and a smaller one above on each side, small eyes, large nostrils, a high back and radiating striæ on the gill-cover. The color is a golden olive, lighter underneath.
These delicate fish, having become acclimated, and finding the Hudson River suitable to their wants, are increasing rapidly in size and numbers; but none that I have seen equal the western carp or are properly game fish.
