Origin of Name
The English name "grayling" is doubtless derived from its appearance in the water, where it glides along like a swiftly moving gray shadow. In Germany it is called asche, from its gray or ash color in the water. One of its old names in England on some streams was "umber," a name of like significance.
As a Game- and Food-Fish
As a game-fish, the grayling is considered by those who know it best, both in this country and England, when of corresponding size, equal to, if not superior to, the brown trout of England, the brook trout of Michigan, or the red-throat trout of Montana; while as a food-fish it is also better, its flesh being firmer, more flaky, and of greater sweetness of flavor. Likewise one can relish the grayling for many consecutive meals without the palate becoming cloyed, as in the case of the more oily trout. It never has a muddy or weedy taste.
In England there is a prevalent opinion that the grayling has a tender mouth and must be handled very gingerly when hooked; there is no truth in this notion, however, as its mouth is as tough as that of the trout; but as smaller hooks are employed in grayling fishing they are more apt to break out under a strain. For this reason the angler should not attempt to "strike" at a rising fish, but allow it to hook itself, which all game-fishes will do nine times out of ten. The only object in striking is to set the hook more firmly.
Grayling Fishing
Grayling fishing is fair during summer, but is at its best in autumn; and where the streams are open it is quite good in winter. Mr. Dugmore, who made the admirable photograph illustrating this article, did his fishing late in August, in the West Fork of the Madison River, and in Beaver Creek in the upper cañon of the Madison, in Montana. The upper Madison is an ideal home for grayling, the stream being clear and swift with a bottom of black obsidian sand.
