THE VENDACE.
The very remarkable fish called the Vendace is to be found but in one place in the three kingdoms,—the Castle Loch of Lochmaben, a parish to the south of Dumfriesshire in Scotland. The Vendace, it is said, derives its name from Vendois in France, and was brought to this country by one of the James's. This, however, is mere conjecture, and, from its habits, highly improbable—because they die the moment they are either touched or exposed to the air.
According to Mr. Stewart (Elements of Natural Hist.), the Vendace belongs to a species which he calls Salmo albula, or the "Juvangis."
"This species," he adds, "is found in Lochmaben in Scotland, and nowhere else: it is said to have been carried thither from England in the time of Robert the Bruce."
Mr. Stewart describes the fish, but from his description it is evident he has never seen it. The following one is exact:—
"This beautiful fish measures from four to six inches in length, and tapers gradually to the tail. When taken out of the water, it has a bright silvery white appearance, with a slight tendency to a light blue along the back and part of the sides. In size it resembles a small herring or par, but particularly the former, not only in the mouth and external appearance, but also in the anatomical structure. Upon the top of the head there is a very distinct shape of a heart, covered with a transparent substance of a brownish colour, resembling a thin lamina of mica slate, through which the brain is visible. This peculiar mark proves it to be as yet a distinct and undescribed species. Nothing is ever found visible to the naked eye in the stomach of the Vendace. They are extremely delicate, and are allowed to be the most pleasing to the taste of all fish. The general mode of catching them is with a net, as there is no instance known of their having been caught either with bait or the artificial fly. The pike, with which this lake abounds, is their greatest enemy. It has been frequently stated that no fewer than fifteen distinct species of fish, fit for the table, have been found in the Castle Loch."
Dr. Knox, sometime Lecturer upon Anatomy in Edinburgh, states:
"That he has not only discovered the food of the Vendace, but actually exhibited it before the Members of the Royal Society, and offers suggestions for the stocking of the various lakes in Britain with this exquisite fish; pointing out first the necessity of locating its natural food, without which it cannot live."
Allowing, however, that some neighbouring lake could be covered with some of these invisible and "incredibly minute entomostraceous animals," which the learned lecturer says constitute their food, we should still find a difficulty in transferring the fish; as every attempt to do so, though conducted with the greatest possible care and nicety, has failed.
