Salvelinus fontinalis
A hard-biting, non-native char that tolerates cold, thin water and is often targeted for harvest to protect native species.
Brook trout feed hard from ice-out through early summer, then again in fall as they stage to spawn, typically September into October. Fall fish are aggressive and often at their fattest before spawning. Winter is also prime time in BC. Brook trout handle cold, low-oxygen water under the ice better than rainbows, making them one of the most reliable ice fishing targets in the province.
Early morning and dusk produce the most consistent action in open water, especially on overcast days when fish move shallow to feed. Through the ice, brook trout often stay catchable across the whole day, including midday.
In small lakes and ponds, still-fishing bait under a slip float near drop-offs and inlet/outlet creeks is hard to beat, and slow trolling small spoons or spinners covers water well. In streams and beaver ponds, work upstream with spinners or drift nymphs through pocket water and undercut banks; brookies hold tight to cover and hit fast. Through the ice, jig a small spoon or jig tipped with bait just off bottom in 2.5 to 3.5 metres of water and be ready for an aggressive strike.
Look for cold, clean water: headwater creeks, beaver ponds, spring-fed streams, and small high-elevation lakes. Brook trout are an introduced species in BC, established through decades of stocking, and they persist in waters that are often too cold or low in oxygen for rainbow trout to thrive. In lakes, target shoal edges, inlet and outlet creeks, and weed-line drop-offs.
