Is, in Icthyology, the English name of a common fish of the Asellus kind, called by some Asellus Mollis, and by others Asellus Albus, or Merlangus. It is certainly, according to the Artedian system, one of the Gadi; distinguished by that author by the name of Gadus with three fins on the back; without beards, with a white body; the upper jaw longer than the lower. The Whiting, or Gadus Melangus of Linnæus, has a very elegant form: its eyes are large, its nose sharp; the teeth of the upper jaw are very long, and appear above the lower when closed. The first dorsal fin has fifteen rays, the second eighteen, and the last twenty. The head and back are of a pale brown colour; the lateral line white and crooked; the belly and sides silvery; the sides being marked lengthways with yellow. They appear in the sea, by large shoals, in the spring, keeping at the distance of about half a mile to that of three miles from the shore. They are the most delicate and wholesome of any of the genus, and seldom grow to more than ten or twelve inches in length. A DISCOURSE OF FISH AND FISH-PONDS, BY The Hon. ROGER NORTH. A DISCOURSE OF FISH AND FISH-PONDS. _Of the Situation and Disposition of the principal Waters._ One great point in the conduct of fish, is, to have them at command; another is, to have perpetual recruits, to supply your stock as you draw it off. This is not to be done without a certain order and method; and with it, nothing is more practicable and easy. Your method must be, to have some great waters, which are the head-quarters of the fish, from whence you may take, or wherein you may put, any ordinary quantity of fish. Then to have stews, and other proper auxiliary waters, so as you lead the fish from one to the other, whereby you never shall want, and need not abound; and, which is more, lose no time in the growth of the fish, but employ the water, as you do your land, to the best advantage. This will appear more distinctly in the sequel of this discourse, which shall begin with the situation and disposition of the principal waters, whereupon you must depend for the raising and feeding the greatest part of the stock. First, you must examine the grounds, and find some fall betwixt two hills, as near a flat as may be, so as there be a sufficient current for the water. If there be any difficulty in judging of such, take an opportunity after some sudden rain, or the breaking up of a great snow in winter, and you shall see plainly which way the ground casts; for the water will take the true fall, and run accordingly.
