The Dolly Varden Trout (Salvelinus parkei)
The Dolly Varden, or bull-trout, sometimes erroneously called "salmon-trout," is the only red-spotted trout native to Western waters. It belongs to the same genus as the Eastern brook trout, but grows much larger. It is found only on the Pacific Slope, in both lakes and streams, growing to twelve or fifteen pounds under favorable conditions. In the streams it is a gamer fish than in lakes, though the larger fish are rather lazy and logy. Compared with its Eastern relative it is hardly so vigorous on the rod, when of similar weight, and not quite so good for the table.
It takes the fly readily, also any kind of natural bait, and in lakes or broad streams succumbs to the trolling-spoon. It is not so great a favorite as the other Western trouts, except in Alaska, where it is abundant in all lakes and streams.
The Brown Trout (Salmo fario)
The brown trout is the brook trout of Europe, and was introduced to the United States from England and Germany, under the auspices of the United States Bureau of Fisheries. Those from Germany (the eggs), were donated by Von Behr, and his name was unfortunately applied to the fish as "Von Behr trout," also "German trout," two most unfortunate and ridiculous names. It is the "brook trout" of Europe and "brown trout" of Great Britain. In Germany it is "bach forelle," which means brook trout. Among English-speaking people it has been known since before the day of Walton and Cotton as "brown trout," and brown trout it should be world without end. To rob this fine fish of its good name and substitute the misnomers mentioned was both unwise and absurd.
Absurd Names
I sincerely hope that those names, together with the equally absurd name of "black-spotted trout," as applied to the red-throat trout, will soon be relegated to the shades of oblivion, never to be mentioned in polite angling society. If the fish mentioned was the only black-spotted trout inhabiting its native waters, it would be a good and suitable name, but unfortunately its congeners, the rainbow and steelhead trouts, are also "black-spotted" as before mentioned. The name originated, I think, about the same time as "Von Behr." When the first eggs were taken East and hatched the fry were called Rocky Mountain trout and California trout, the former name being more applicable than the latter, but neither were very suitable. Our technical knowledge of the Western trouts must have been sadly deficient, however, when they were displaced for "black-spotted trout."
As a Game- and Food-Fish
The brown trout has both reddish-brown and black spots, of a larger size than those of its American cousins. Altogether it is a fine fish, much prized in Great Britain, but in American waters it is hardly so gamy, and not quite so good a food-fish as our native trouts. It grows to a larger size than our brook trout, and will thrive in warmer water. A variety of the brown trout, the Loch Leven, was introduced into Firehole River, in the Yellowstone National Park, some years ago, and it is remarkable how well they thrive in the warm geyser water. They must have been planted in some stream in the Park tributary to the Yellowstone River also, for I know of two being taken near Livingston, Montana, one weighing more than ten pounds, the other about twelve. In a pond near Bozeman, Montana, some brown trout fry were planted, and at the end of four years two were taken weighing six pounds each, both of which were weighed by myself.
