Brook Trout

Salvelinus fontinalis

Also known as

  • Brookie US
  • Speckled Trout US
  • Squaretail US
  • Brook Char US
  • Salter US
  • Coaster US

Identification

Compact small-stream char built for tight pocket-water hunting. Stream residents stay slender and rarely exceed 30cm; sea-run (salters) and lake-form (coasters) fish grow far heavier. Spawning males develop a vivid orange-red belly.

  • Pale worm-like vermiculations across olive-green back and back fin
  • Red spots ringed with blue halos scattered along the flanks
  • Pink-to-orange lower fins and belly intensifying at spawning
  • White leading edges with a black stripe behind on the lower fins
  • Small adipose fin between back fin and tail

Where it holds

  • Rivers
  • Lakes
  • Estuaries

Behaviour

An aggressive opportunistic coldwater predator and one of the most willing strikers of all salmonids — famously eager to attractor flies and small spinners. Diet centres on drifting insects, terrestrials, and small baitfish; lake and sea-run forms add scuds, sculpins, and smelt. Peak 10-16°C (50-61°F); bite drops sharply over 18°C (64°F); fish retreat to spring seeps over 22°C (72°F). Dawn and last-light dominate stream feeding; lake coasters cruise shallow shorelines through cool seasons.

Diet: Aquatic Insects, Terrestrial Insects, Baitfish, Crustaceans, Salmon Eggs

How it's caught

Fly Fishing

Dry Fly

The signature method. Cast attractor and hatch-matcher dries upstream into pocket water, plunge-pool tailouts, and undercut banks; let them drift drag-free through feeding lanes. Brook trout are the least selective of the trouts — accuracy and stealth in tight quarters matter more than imitation. Hopper and ant patterns shine summer through autumn. Light wrist-snap hooksets only on these soft-mouthed fish.

Nymphing

Drift small bead-head nymphs under an indicator or as a dropper below a buoyant dry through pool tailouts, riffle heads, and pocket water. Tight-line Euro-rigs are deadly in deeper plunge pools. Set fast on any pause or twitch — brook trout often hold the fly briefly before rejecting.

Wet Fly

Swing soft-hackles and traditional wets across and downstream through pools and runs. Mend to control depth; takes come on the hang at the end of the swing. Especially productive in cool early-season water and on pressured streams where dry-fly response thins.

Streamer

Strip small streamers along undercut banks, deep pool heads, and lake drop-offs to target larger fish — sea-run salters and lake-dwelling coasters are the prime audience. Sink-tip lines for lake work; floating with weighted streamer in streams.

Line Fishing

Spinning

Ultralight cast inline spinners (Panther Martin, Mepps size 0-2), tiny spoons (1-3g Kastmaster, Thomas Buoyant), and small jerkbaits to pools, pockets, and beaver-pond shorelines. Cast across-and-down with steady retrieves; brook trout strike hard and immediately. Light line and stealth approach on small streams.

Float Fishing

Slip-bobber a worm, salmon-egg cluster, or small piece of PowerBait through pools and over weedy lake shelves. Set bait 30-60cm off bottom with light split-shot. The simplest highly effective method on stocked ponds and easy-access streams — well-suited to beginners.

Ice Fishing

Jig small tungsten jigs and tiny spoons tipped with waxworms or salmon eggs over lake shelves, weed edges, and inflows. Brook trout suspend in the upper water column under ice — work the top third before dropping deeper. Run a tip-up with a live minnow on the second hole.
