Brook Trout (Salvelinus fontinalis) lives in lake Superior across Eastern North America. It feeds on insects and crustaceans. Its conservation status is Least Concern.
Fascinating facts about the Brook Trout
- Coaster brook trout can grow over 2 feet long and tip the scales at 6.8 kg (15 lb), while their short-lived cousins, the salters, stay between 6 and 15 inches and weigh only 0.5-2.3 kg (1-5 lb). This size gap reflects their different life strategies: coasters linger in large lakes, whereas salters sprint to the sea and return to streams to spawn. The contrast shows how a single species can split into dramatically different ecological roles.
- The biggest brook trout ever recorded was a 6.57 kg (14 lb 8 oz) monster snagged on the Nipigon River in Ontario in July 1916, still listed as the IGFA world record. That single fish dwarfs the typical 0.3-3 kg range.
- Brook trout can live much longer than most people think: while most individuals die by age 5-8, some California introductions have been documented at 15 years old, and wild specimens can reach seven years or more.
- A female brook trout can lay up to 5,000 eggs in a gravel "redd", which then incubate for 4-6 weeks before hatching. Although usually a single male fertilises the clutch, occasional multiple-male fertilisation occurs.

About the Brook Trout
In the crystal clear waters of its native streams, the brook trout dances with effortless elegance, its mottled brown and green scales blending seamlessly with the dappled shade of the riverbed. With each flick of its tail, it darts and weaves through the submerged vegetation, a fleeting glimpse of bronze and silver as it chases the ephemeral currents in search of sustenance. As it glides through the water, its very presence seems to embody the essence of the wild, a symbol of resilience and adaptability in the ever-changing landscape of its aquatic world.
