Brown trout are the trout that keep experienced anglers humble. Introduced from Europe, they are the most wary and the most predatory of our common trout, and they hold over from year to year better than the others, so the browns in a given water are often the biggest, smartest fish in it. Fooling a good brown is one of freshwater's genuine accomplishments.
How to identify them
Brown trout are golden-brown to buttery bronze with black and red or orange spots, many of them ringed with pale halos, and few or no spots on the tail. Compare with the brook trout (dark with pale worm-like markings and blue-haloed red spots) and the rainbow (pink stripe, heavily spotted tail). That halo-ringed spotting is the brown's signature.
Where they live
Browns thrive in rivers, streams, ponds and lakes across New England, both stocked and, in some waters, holdover or wild. They favor cover and structure, undercut banks, log jams, boulders, deep pools, and the biggest fish are famously nocturnal and structure-bound. A big brown does not get big by being careless.
Tip The best browns bite in low light. Fish the first and last hour of the day, and overcast or stained water, when big, wary browns drop their guard and hunt, especially for a streamer swung near cover.
How to catch them
Fly
Browns are a premier fly-rod target. Nymphs fished deep (see nymphing for trout), streamers stripped and swung near cover for the predatory big fish, and dry flies during a hatch all take browns. A 5-weight setup covers most of it.
Spin
Inline spinners, small spoons, jerkbaits and, for stocked fish, bait all produce. Big browns will eat a good-sized minnow or swimbait.
Handling
Wild and holdover browns are a resource worth protecting. Use barbless hooks where you can, keep the fish wet and in the net, handle it as little as possible, and revive it fully, particularly in warm water, when trout are most fragile.
