Brown Trout

Predatory fish
Brown Trout

Brown trout is the native European trout of cold, clean rivers. Has a spotted pattern with red dots ringed in blue. Reaches weights of 15 kg.

Feeds on insects (both aquatic and terrestrial), larvae, crustaceans, and fry. Larger specimens become fully committed fish predators.

Most active at 6–16 °C. Requires cold, oxygen-rich water. Peak activity in spring and autumn. Becomes lethargic during summer heat. Feeds better in overcast weather and light drizzle.

Holds on riffles, behind boulders in current, and under overhanging vegetation. Each trout defends its own territory.

Caught on fly fishing (dry and wet flies), crankbaits, spinners, and worms. Fly fishing is the classic trout method. Spinning with micro-lures is also effective.

For trophy brown trout: large streamers and crankbaits (7–12 cm), fish at dawn and dusk. Big trout hold in deep pools below riffles. Stealth and delicate presentation are critical.
