Currier & Ives, Brook Trout, 1868, chromolithograph, Library of Congress.
If you fly fish, sooner or later you hear two things:
- You idiot. Brook Trout aren’t a trout.
- Brook trout have been driven out of their native range.
The first, that brook trout aren’t a trout, isn’t so much spoken as declaimed. Those aren’t trout! Those are char! What’s actually being said is that brook trout, Salvelinus fontinalis, are taxonomically closer to members of the genus Salvelinus, commonly called char, than they are to brown trout, Salmo trutta, always called trout. Of course that begs the question of why rainbow trout, Oncorhynchus mykiss, get a pass on trouthood when they’re taxonomically closer to Pacific salmon than to brown trout. And that begs the question of why Atlantic salmon (Salmo salar) are a salmon when they’re taxonomically closer to brown trout than to Pacific salmon.
These are probably the sorts of existential questions that trout ponder, but for me at least there’s some irrelevance to it. One supposes that all that taxonomic relativity means something scientifically, but common usage is common usage, and it’s brook trout, not brook char. One also supposes that the taxonomic classification of beetles is just as confusing as the various fishes, but likely as not every time you say June bug no one says that’s not John but Paul.
Questions about brook trout range are much more interesting. There was a time, roughly coinciding with somewheres in the Pleistocene to 1883, when brook trout were the only river trout in eastern North America. They ranged from Georgia to as far west as Michigan and north into Canada. By the 19th Century the Catskills were the destination fishery for New York, like now New Zealand and Iceland and Christmas Island and Kansas are the destination fisheries for modern anglers, and without cars or even trains the Catskills weren’t much easier to get to than Christmas Island. When in 1830 you fished the Catskills for trout you fished for brook trout, and I suspect that no officious busybody butted in to to tell you that’s not a trout it’s a char.
Brook trout first declined in much of their native range because of over-fishing and habitat degradation. Meanwhile innovators were beginning to raise hatchery brown trout, and the browns were adaptive and more heat and environmentally tolerant. Brown trout were first introduced into Michigan, but their introducers quickly took them east. Rainbows from the west coast were also introduced. While being crowded out of the east, brook trout meanwhile were carried west, and, along with their cousin the lake trout, brook trout are now an invasive species in cutthroat habitat. Poor cutthroat. They catch it from everybody.
By the way, lake trout (Salvelinus namaycush) are not a trout but a char.
There are efforts by the the Eastern Brook Trout Joint Venture, a coalition of states, local governments, and private entities, to restore brook trout populations and habitat in their native range and to preserve the rivers and lakes where brook trout populations are healthy. the following Joint Venture map is dated, but it indicates where to fish for native brook trout. Maine. Go to Maine. And northern New Hampshire.
Hey! We’re on our way to northern New Hampshire!
Brook trout, which are members of the char family, spawn in the autumn beginning in their second year. I came across this peculiarly lurid description of brook trout spawning on a U.S. Fish and Wildlife website:
Pre-spawning courtship of the brook trout begins with the male attempting to drive a female toward suitable gravel habitat to facilitate spawning. A receptive female chooses a spot and digs a redd. While the female brook trout is digging, the male brook trout continues his courtship activity, darting alongside the female and quivering, swimming over and under her and rubbing the female with his fins.

Dang. These are your government employees at work. Pretty salty stuff.
And speaking of salt, like rainbows brook trout can move into the ocean (in which case they’re called salties). They return to freshwater to spawn.
If there’s a creature that a brook trout can put in their mouth, they’ll eat it. They feed by sight, so they’re daytime feeders. They’re short-lived, commonly living three to four years. Their size varies based on habitat.
Man they’re pretty. They’re also not a trout, but a char.
Four to eight pound brook trout are trophies. All of the IGFA tippet class records for brook trout are from Canada, and range up to about 10 pounds. The all tackle record is a bit more than 14 pounds. Weirdly all of the women’s records are vacant except for two pound tippet, which is for a 2 lb 8 oz fish. Kris really does need to get busy.
