Salmo trutta
The wariest trout in the river and the one that grows into a night-hunting predator. Big browns eat mice, chubs, and other trout — catching one on purpose is a merit badge.
Fish bigger, darker, and later than you would for rainbows. Browns hold in the heaviest cover of the pool and feed in low light — streamer and jerkbait fishing shines.

Use these field marks and context clues to separate brown trout from similar fish before logging or keeping one.
Match a rig to Brown Trout with the Setup Builder, or browse all setups.
Float rivers casting streamers to the bank — cover miles.
Same float game, quieter; anchor above prime pools at last light.
Small-stream stalking or big-river bank walking at dusk.
Cold rivers and tailwaters nationwide, plus Great Lakes tributaries; tolerate slightly warmer water than other trout.
Browns are butter-gold with red-haloed spots and few or no tail spots.
Brookies have light spots on dark background and white-edged fins — the reverse of a brown's dark-on-light.
Size limits, bag limits, seasons, and gear rules change every year and differ by state (and often by individual water). Always verify with the official source before keeping fish.
