By some this is deemed a mere variety of Brook Trout, improved and developed by sea voyaging. Salmon-Trout are higher flavored and deeper colored than either Brook or Lake Trout. They frequent the St. Lawrence River and its tributaries, and many smaller streams that empty into the ocean from Long Island and the Eastern States. Like Salmon, these fish run up to fresh-water river-heads and shallows during spawning time. Usual weight from two to five pounds. Salmon-Trout are greedy feeders and make havoc among minnows and other small fish. Unlike Salmon, their stomachs are, normally, gorged with food. When in full season, and tolerably fresh from the sea, Salmon-Trout are bright; but as autumn spawning-time approaches, the fish lose their brilliancy and acquire a reddish or blackish tinge. For angling use rod from ten to twelve feet; line of two hundred feet with click-reel ; leader of silk-worm gut;. Salmon hooks Nos. 3 and 4; flies of various colors, particularly red or orange ones.
